#KRAIN: Infrastructure for the AI Economy

Whitepaper v2.1 — Work in Progress · Revised after community review

⚠️ This is a working draft, not a final document. It is published openly so the community can read it, pull it apart, and help shape the final version. Specific dates, contract addresses, and final parameters will be confirmed prior to mainnet. Nothing herein constitutes an offer to sell securities.

🗣️ We're still reading your feedback. v2.1 reflects what the community and our partners told us during the v2.0 review period. We're keeping the loop open — tell us what's strong, what's unclear, and what you'd change. Discuss it in the dedicated feedback channels: #whitepaper-v2 on Discord · Join the discussion on Telegram

#You said → we changed (v2.0 → v2.1)

We ran the v2.0 whitepaper as an open draft and read everything. This revision is the result. Highlights of what changed in response to the community and our partners:

• We made the "total community picture" explicit. The direct community airdrop is not the only way the community shares in KRAIN — see §5.2.
• We said the vesting terms up front, in plain language, so nobody is surprised at TGE (§5.3).
• We hardened the vesting trust design — smart-contract custody, a longer inactivity window, a clear definition of "active," no claim-slashing, and a named fate for unclaimed tokens (§5.3). (Thanks to @ebubedikefx, @scarrius, @cryptorovia for the detailed spec.)
• We separated TGE from listing. At TGE, $KRAIN is for use on supported apps — there is no market and no price; a listing comes later, only when conditions support a fair opening value (§5.9). (Thanks to @zackcamuh for pushing on demand drivers.)
• We addressed Key Holders / Founders Key directly (§5.2). (Thanks to @novel64 for keeping this on the table.)
• We tied team and founder vesting to milestones, not the calendar — no team release before mainnet, and the rest unlocks only as the protocol hits real milestones (§5.3). (On our market-maker partner's recommendation.)
• We added the launch sequence so the order of events is clear: each milestone gates the next, and each date is announced when that milestone is real (§6).
• We answered the recurring eligibility, wallet, and account-linking questions in one place (§5.2).

Some calls — the headline community percentage, the season split, and the exact XP-to-token math — are still open and will be set with the community ahead of the snapshot. We'll keep showing our work.

#1. Executive Summary

KRAIN is the infrastructure layer for the AI economy. The project began as a consumer-facing AI app portal and has grown into a stack that now spans three layers:

1. The KRAIN Marketplace — a live discovery, reputation, and quest platform with a community of more than 150,000 across X, Telegram, and Discord. This is the product layer users interact with today.
2. The KRAIN Protocol — an AI-native L2 blockchain (EVM-compatible optimistic rollup) designed so that autonomous agents can execute, transact, and be priced as first-class economic actors.
3. The $KRAIN token — a fixed-supply utility and governance token whose value accrues from three on-chain revenue streams: sequencer margin on inference transactions, a 0.05% agent tax on x402 micropayments, and a 1% protocol fee on Initial Agent Offering (IAO) bonding curves.

Most AI x crypto projects sit on one side of a divide. Infrastructure-only projects raise large rounds but ship no product. Token-first projects accumulate market cap with no end-user surface. KRAIN combines a live product with the underlying agent execution layer that product needs as it scales.

Traction. The marketplace is live today with an engaged community of 150,000+ across X, Telegram, and Discord, an active quest and review system, and ambassador and creator programs running. (We deliberately lead with engagement rather than raw registration counts, which over-state real activity.)

Funding. KRAIN is bootstrapped to date and is currently raising a pre-seed round. Fundraising updates are shared through official channels.

This paper specifies the architecture, the token, and the path from today's marketplace to a fully on-chain agent economy. Value is made, not allocated — the economics in §5 are designed so that real usage, not a headline number, is what gives $KRAIN its worth.

#2. The Problem

The AI ecosystem in 2026 has three structural gaps that the open internet alone cannot close.

Discovery and trust are fragmented. New AI apps and agents are launched daily. Quality, performance, and safety are difficult to compare. There is no neutral, structured directory with verified review data, performance metrics, and an incentive system that rewards honest curation rather than promotion budget.

AI inference is opaque. When a user calls a hosted model, they cannot verify that the model executed the prompt they sent, that the output was generated by the model they paid for, or that compute was billed honestly. This is acceptable for casual use. It is unacceptable for high-value agent workflows — financial agents, medical workflows, autonomous trading, governance decisions — that depend on auditable execution.

Agents have no native economic layer. Today's agents call APIs, settle payment in fiat through aggregators, and cannot easily own assets, transact directly with other agents, or be tokenized in a way that aligns incentives between agent developers and end users. The plumbing for an agent economy exists in fragments — wallets, identity standards, payment protocols — but no single chain has assembled them into a coherent execution environment.

KRAIN addresses all three. The marketplace solves discovery and trust at the application layer. The protocol solves verifiable inference and agent economics at the infrastructure layer.

#3. The KRAIN Marketplace

The KRAIN Marketplace is the live product layer of the ecosystem. It is built around three pillars.

Structured discovery. AI apps and agents are listed in a searchable directory categorized by use case, model family, and performance. Discovery is natural-language-first: users can search in plain language — "agents for automating invoicing," "crypto compliance bots" — and receive personalized recommendations based on use case, model family, and prior activity, rather than navigating rigid category trees alone. Every listing supports verified reviews, structured performance data, and quest tasks that route users into hands-on evaluation rather than passive browsing.

Reputation and rewards. Users earn quest points for verified reviews, daily streaks, referrals, governance participation, and platform engagement. The points system has been operational since launch and currently underpins the airdrop allocation framework. Quest design favors signal over volume — low-effort engagement is capped, and review quality is weighted by accuracy and depth. Community signals — verified reviews and upvotes — feed a ranking that surfaces the highest-quality agents, so the best tools rise on merit rather than promotion budget. (Eligibility and anti-farming detail is in §5.2.)

Ambassador and creator programs. A multi-tier ambassador track recognizes long-term contributors. Creator programs route ecosystem grant funds to high-quality reviewers, content producers, and community moderators. Earned community roles (such as Ambassador, OG, and Kartel roles) are recognized within the contributor framework described in §5.2.

The marketplace today aggregates user demand. Once the protocol is live, the same user base becomes the natural entry point into the on-chain agent economy: each listed agent can graduate from a hosted listing into a fully tokenized, on-chain Smart Agent without the user having to learn a separate brand or interface.

#4. The KRAIN Protocol

The KRAIN Protocol is an AI-native L2 blockchain. In plain terms: it is a Layer-2 chain (it settles to Ethereum for security and lower cost) whose execution environment is purpose-built for AI — it can run and verify machine-learning work directly, instead of only recording the results of AI that ran somewhere else. It is the substrate that lets agents execute verifiably, transact natively, and be priced as economic actors.

#4.1 Architecture overview

KRAIN Protocol is an EVM-compatible optimistic rollup with a dual virtual machine:

• EVM for Solidity contracts: tokens, DeFi primitives, factories, bridges.
• WASM (Rust-based) for Smart Agents and the AI Virtual Machine (AIVM), giving agent code direct access to tensor primitives.

The chain settles to Ethereum L1 and uses a separate data availability layer for inference execution traces. The specific L1 partner and DA configuration will be selected based on cost, security, and ecosystem alignment.

            +----------------------+
            |     Ethereum L1      |   <- settlement
            +----------+-----------+
                       |
            +----------+-----------+
            |     KRAIN L2         |
            |  EVM + WASM (Stylus) |
            |  AIVM precompiles    |
            |  opML bisection      |
            +----------+-----------+
                       |
            +----------+-----------+
            |  Data Availability   |   <- execution traces
            +----------------------+

#4.2 The AI Virtual Machine (AIVM)

The AIVM is a set of tensor operations exposed to the WASM runtime as host functions. Smart Agents call them directly, the same way a normal smart contract calls keccak256 or ecrecover.

The first set of precompiles includes:

• matmul — dense matrix multiplication
• relu, sigmoid, tanh, softmax — activation functions
• conv2d — convolutional inference for vision workloads
• attention — scaled dot-product attention block

Tensor precompiles are the difference between an L2 that "supports AI" by hosting GPU billing wrappers and one that lets AI execution be expressed in contract code with deterministic gas costs.

#4.3 Smart Agents

A Smart Agent is the on-chain representation of an autonomous AI agent. Each agent has:

• A contract (Rust/WASM via Stylus) that defines its behavior.
• A wallet (ERC-6551 Token Bound Account) that lets the agent hold assets, sign transactions, and pay other agents.
• An identity (compatible with ERC-8004 trustless agent identity standards) that supports on-chain reputation.
• Optional content provenance (ERC-7007) so outputs produced by the agent can be cryptographically attributed.

The AgentFactory contract lets a developer deploy a new Smart Agent in a single transaction. Templates cover common patterns: research agent, trading agent, customer-support agent, content agent, data-pipeline agent.

#4.4 Optimistic Machine Learning (opML)

Running heavy ML inference on-chain is impractical today. KRAIN uses an optimistic verification model. This is in active development and runs on the KRAIN devnet — it is not yet a production mainnet system. The design works as follows:

1. A solver node runs the inference off-chain on real hardware (GPU) and posts the result on-chain together with a bond and a hash of the execution trace.
2. The full execution trace is published to the DA layer.
3. A configurable challenge window (default: two hours for high-value calls, instant for low-value calls) allows any watcher node to dispute the result.
4. Disputes are resolved via a bisection game: the chain narrows the disagreement to a single instruction step and adjudicates that step on-chain. The losing side forfeits its bond; the winning side is rewarded.

Honest solvers always win. Fraudulent solvers are slashed. This is the same model that secures fraud-proof rollups today, adapted to neural-network inference. The approach is grounded in published opML research and matches the verification philosophy of optimistic rollups already securing tens of billions in TVL.

#4.5 The IAO Factory (Initial Agent Offering)

The IAO Factory is a permissionless launchpad for tokenized AI agents.

A developer deploys a Smart Agent and an Agent Token in one transaction. The Agent Token is sold against ETH or USDC on a bonding curve. (A bonding curve is a smart contract that sets the token's price by formula as supply is bought or sold — early buys are cheaper, later buys cost more — so price discovery is automatic and rule-based, with no privileged early access and no separate exchange needed.)

When the bonding curve reaches its graduation threshold (default: ~80% of supply sold, targeting roughly $500K market cap), the contract automatically:

1. Halts further bonding-curve trades.
2. Seeds a Uniswap V3 pool with the remaining tokens and accumulated reserves.
3. Locks the LP NFT in the factory contract so liquidity cannot be withdrawn.

Protocol fee: 1% of trade value on every bonding-curve buy or sell, paid to the KRAIN treasury. Developer fee: 1% of trade value, paid to the agent's creator wallet.

Agents that earn real revenue post-graduation can opt in to a fee distributor contract that streams a share of inference earnings back to Agent Token holders. This converts an agent token from pure speculation into a revenue-sharing instrument when the underlying agent is productive.

#4.6 The x402 Payment Gateway

x402 is the open standard for HTTP-native micropayments: when an agent requests a resource, the responding server can reply with HTTP 402 and a payment instruction. KRAIN routes x402 payments through a settlement contract that takes a 0.05% protocol fee (the "agent tax") on each transfer. The remaining 99.95% reaches the recipient agent.

Batch settlement reduces per-transaction gas cost so that micropayments down to fractions of a cent remain economically viable. The fee rate is set deliberately below typical payment processor margins so that agent-to-agent commerce is not bottlenecked by KRAIN's economics.

#4.7 The Inference Router

The Inference Router is the facade that routes an inference request to the right solver. It considers cost, latency, model availability, solver reputation, and slashing history. Solvers register, stake, and earn reputation over time; persistently dishonest solvers lose bond and reputation.

This is the same role a load balancer plays in a Web2 cloud — except that solver performance and honesty are observable on-chain.

#5. The $KRAIN Token

The $KRAIN token is the single native economic asset of the KRAIN ecosystem. It is a utility and governance token, not a gas token (gas on KRAIN L2 is paid in ETH, consistent with standard optimistic rollup design).

What drives demand for $KRAIN. Beyond staking and governance, sustained demand comes from real protocol activity: agents and users spend on supported apps and services; premium marketplace features and listing promotion are payable in $KRAIN; the IAO launchpad charges a fee in protocol terms; x402 routing and solver collateral consume the token's economic surface; and protocol revenue funds a buyback (§5.6). These are usage-driven, not narrative-driven. This is the core idea of the token design — value is made through use, not assigned by a number.

#5.1 Supply and core parameters

#5.2 Distribution

The total community picture. The 8% line above is the direct community airdrop — it is not the whole of what the community receives. Community members and contributors also draw from the 30% Ecosystem & Developer Fund (grants, hackathons, builder and creator programs, retroactive rewards) and, where applicable, from the contributor recognition described below. The headline percentage is one channel, not the total upside. (The exact direct-airdrop percentage and the season split remain open and will be set with the community ahead of the snapshot — see §5.4 and the roadmap.)

The allocation profile is in line with established L2 precedent (Arbitrum, Optimism). Team allocation is slightly lower than Arbitrum's 27% to reflect a lean founding team and to bias more supply toward ecosystem growth.

Pre-Formation Contributor Recognition Programme

KRAIN operates a standing Pre-Formation Contributor Recognition Programme for individuals and teams who contributed to the project before the protocol's formal formation — including early contractors, moderators, ambassadors, creators, and other operators. This is the project's standard, discretionary programme.

Pool. A fixed allocation of 10,000,000 $KRAIN — 1% of total supply — is reserved for this programme, drawn from the Team & Founders and Ecosystem & Developer allocations above. This creates no additional dilution.

Allocation rule. Allocations are determined by contribution units, calculated as:

Tier weight × months of verified active contribution, capped at 24 months.

Tier weights reflect the nature and extent of contribution at the project's discretion:

An individual's allocation is: (your contribution units ÷ total contribution units across all recognised contributors) × 10,000,000 $KRAIN

Vesting. Allocations are distributed in $KRAIN under standard contributor vesting terms.

Discretion. This programme is wholly discretionary. Whether, when, to whom, and in what amount any allocation is made remains at the project's sole and absolute discretion. $KRAIN is a utility token: allocations under this programme carry no guaranteed monetary value, are not redeemable for fiat, and are not compensation denominated in any currency. Tier assignments and verified months for each recognised contributor are determined at the project's sole discretion.

Key Holder / Founders Key. KRAIN recognizes Founders Key / Krain Pass holders. v2.1 confirms the commitment is honored; the precise mechanics — whether the Key allocation sits inside or outside the community airdrop percentage, the status of the holder multiplier, and the distribution timing — are being finalized and will be published ahead of the snapshot through official channels.

Eligibility, anti-farming, and fairness. Eligibility is based on verified contribution across the program phases (Origin, Intract Alpha, Catalyst, and ongoing marketplace activity). Quality is weighted over volume: low-effort engagement is capped, AI-generated or inauthentic reviews are filtered, and loyalty/recency signals reward sustained genuine participation over short-burst farming. The final eligibility detail — including whether a minimum participation threshold applies — will be published with the snapshot.

Phase weighting. Season 1 combines all pre-TGE phases (Origin, Alpha/Intract, Catalyst, and testnet). Earlier phases are weighted to recognize early support, and both time-and-effort contribution and capital contribution are recognized — the design is deliberately non-zero-sum, not a choice between the two. The explicit per-phase weights and the Season 1 / Season 2 split will be published ahead of the snapshot, and may be put to a community vote once the guardrails are set.

XP → $KRAIN conversion. The conversion from quest points/XP to $KRAIN, a worked example, and the snapshot and wallet-linking process will be published ahead of distribution. The conversion ratio is not yet finalized — please treat any community-circulated ratio as unofficial until we publish it.

Account connectivity and wallets. Eligibility and point accrual are currently based on wallet activity across Origin, Intract Alpha, and Catalyst. If you cannot connect a required account (for example, X/Twitter linking, email, or a Solana wallet) due to a technical issue, this does not by itself forfeit your eligibility — open a support ticket with evidence of participation and the team will assist. Email connection is an upcoming feature still in development. For contributions originally earned under a Solana address, the team provides a path to link an EVM wallet for $KRAIN (an EVM token) distribution; guidance is available through the app and support.

KYC and jurisdictions. Identity verification (KYC) may be required for some distributions or jurisdictions; the scope, if any, will be set out in the final airdrop terms and subject to legal review. A list of excluded/prohibited jurisdictions will be published ahead of distribution via official channels and the Airdrop Terms so that participants have advance notice.

#5.3 Vesting

Plain-language summary for the community airdrop: community airdrop recipients receive 25% of their $KRAIN at TGE, and the remaining 75% vests linearly over 6 months. Yes — the community airdrop vests; this is stated up front so there are no surprises at TGE.

• Community airdrop (80M): 25% at TGE, 75% linear over 6 months. Custody is by audited smart contract that releases vested tokens programmatically without further team approval — not a team-held wallet. Vesting can pause for sustained inactivity (see below) and resumes when the participant returns.
• What counts as "active": ordinary app sign-in / interaction (using the platform). Activity is not defined as paying gas fees or grinding artificial tasks.
• Inactivity window: vesting pauses only after 60–90 days of inactivity (widened from an earlier 30-day proposal in response to community feedback).
• No claim-slashing: there is no additional slashing penalty layered on top of vesting.
• Unclaimed tokens: allocations left unclaimed after the claim window are directed to a Season 2 community loyalty pool or burned — they are not quietly returned to a general fund. The exact treatment will be confirmed ahead of TGE.
• Vesting has upside, not just a lock: vested allocations carry governance weight and are eligible for staking-style fee participation, so holders are not merely waiting (this addresses the "what's the benefit of vesting?" question directly).
• Team and founders (180M): milestone-based release, not a calendar vest. Team and founder tokens are released only as the protocol hits real, verifiable milestones — aligning the team's upside with shipping a working network and with sustained protocol usage, rather than with the passage of time. This reflects feedback from KRAIN's market-maker partner that team release is best optimized to milestones rather than time-vesting.
• No team release before mainnet. A hard floor: zero team or founder tokens unlock until the chain is live on mainnet. The team carries delivery risk first.
• Milestone-gated tranches. After the mainnet floor, the remaining team allocation releases in tranches, each unlocked by a defined protocol milestone tied to the launch sequence (§6) and to concrete protocol traction. A sensible default structure — the exact milestone→percentage split will be confirmed by the project ahead of mainnet:
• Mainnet live (production chain operational) — first tranche unlocks.
• TGE / distribution and $KRAIN spendable on supported apps — next tranche.
• Protocol traction: a target number of supported apps integrated and actively spending $KRAIN — next tranche.
• Sustained protocol-revenue threshold maintained over a defined window (real fee revenue routed through §5.6) — next tranche.
• Primary exchange listing (conditions-gated, §5.9) — final tranche.
• Time as a floor, not a trigger. Where a milestone could in principle be gamed by pulling it forward, a minimum-elapsed-time floor may also apply so milestones can only delay, never accelerate, release. Total allocation is unchanged at 18% / 180M.
• Investors (150M): Pre-seed has a 12-month cliff with a 25% unlock at month 13 and a 24-month linear tail. Future seed rounds use a shorter cliff with a 24-month tail.
• Ecosystem and developer fund (300M): 40M is released monthly-linear (~6.7M/month) over the first six months for grants and hackathons. The remaining 260M is released quarterly by DAO vote over approximately three years.
• Treasury (250M): No automatic unlock. Deployed only by DAO vote.

#5.4 Airdrop seasons

• Season 1 (pre-TGE): combines all existing phases — Origin, Alpha/Intract, and Catalyst (plus testnet participation) — into one TGE allocation. Earlier phases are weighted more, but all phases count. The explicit weights and the Season 1 / Season 2 split will be published ahead of the snapshot.
• Season 2+ (post-TGE): new seasons reward governance, building, staking, and continued network usage, in the multi-season model used by leading L2s.

#5.5 Revenue streams

KRAIN captures revenue from three independent on-chain activities:

1. Sequencer margin on every transaction processed by the L2, with a target margin in the 15–25% range over L1 data-posting cost. The protocol takes 40% of sequencer revenue after operating costs; the sequencer operator keeps 60%.
2. Agent tax of 0.05% on every x402 micropayment settled through the gateway.
3. IAO launchpad fee of 1% on every bonding-curve trade.

These are independent: agent tax revenue does not depend on bonding-curve activity, sequencer revenue does not depend on agent-to-agent payments, and so on. The token's value accrual is therefore robust to which mode of agent activity dominates first.

#5.6 Revenue routing and the buyback flywheel

All protocol revenue flows through a fixed split:

Protocol revenue
        |
        +-- 20% --> Staker reward pool        (paid in ETH, weekly)
        |
        +-- 40% --> $KRAIN buyback & burn     (deflationary)
        |
        +-- 40% --> Protocol treasury         (DAO-governed)

The 40% buyback creates a mechanical link between compute throughput and circulating supply: more inference, more agent payments, more launches → more revenue → more buybacks → less circulating $KRAIN. The 20% staker pool gives long-term holders real ETH yield from real fees, not inflationary token emissions. (Note: the buyback's effect on market price applies once a market exists — see §5.9 on TGE vs. listing.) This routing is modeled on revenue-routing proposals already adopted or under active discussion across major L2s.

#5.7 Staking

$KRAIN holders can stake on KRAIN L2 to earn a share of protocol fees.

Rewards are paid in ETH because that is the currency in which the underlying protocol fees are collected. This preserves the fixed supply of $KRAIN and avoids the dilution dynamics common to inflation-funded staking models.

#5.8 Quest multipliers

$KRAIN holders earn boosted quest points on the marketplace. Tier thresholds and multipliers reward sustained holding:

Tier is determined by a 7-day trailing average of holdings (staked or unstaked), preventing snapshot-timing attacks. Staked $KRAIN counts toward tier — users do not lose multiplier benefits by staking for yield. (Tier thresholds, including the top Protocol tier, are under review based on community feedback and may be adjusted before TGE.)

#5.9 From TGE to listing: utility first

KRAIN follows a utility-first sequence, and it is important to distinguish two separate events:

• TGE (Token Generation Event): $KRAIN is generated and distributed, and becomes spendable for use on supported apps and services. At TGE there is no exchange market and no market price — the token's first role is utility, not trading. Think of it like an in-ecosystem credit that real usage gives meaning to.
• Listing event (later, conditions-gated): once utility-driven demand has built, the market-maker seeds liquidity and a primary listing happens — but only when conditions support opening at a fair value justified by proven demand. There is no committed listing date; listing follows utility, not a calendar.

This is what we mean by value is made, not allocated. Rather than promising a price at launch, the design builds real usage first — spending on supported apps, agent payments, IAO activity, staking yield from real fees, and the buyback flywheel — and lets the market discover value from that usage. The float, liquidity, and any price discussion attach to the listing event, not to TGE.

#5.10 Anti-dump design

Sustained value depends on managing post-listing sell pressure. KRAIN combines several mechanisms:

• Activity-aligned vesting. The community airdrop vests 25% at TGE, 75% over six months, in an audited smart contract, with the inactivity and unclaimed-token terms described in §5.3.
• Milestone-gated team release. Team and founder tokens unlock only as the protocol hits real milestones, with no team release before mainnet (§5.3) — the team's supply enters circulation in step with delivered network progress, not on a fixed calendar.
• Staking yield as opportunity cost. Real ETH yield on staked $KRAIN gives long-term holders a yield floor independent of price.
• Two-season structure. Season 2 rewards continued participation, governance, and staking.
• Quest multipliers. Holders earn more points; tier benefits reward holding.
• Utility-first launch. Because TGE precedes any market (§5.9), there is no day-one trading event to dump into; demand is built before liquidity is seeded.
• Bridge rate limits. When bridging opens, initial L2→L1 bridge limits cap per-address daily withdrawals (500K $KRAIN/day in week one, 2M $KRAIN/day in weeks two through four, unlimited after day 30) with a 1% bridge fee in the first 30 days that flows into the buyback contract.
• Exchange-listing allocation is separate. Community contributor allocation is not pooled with, nor competed against, any exchange-listing allocation — listing-program participants do not reduce the community's share.

#6. Roadmap

KRAIN is shipping in phases. The current phase is foundation and pre-mainnet engineering. The timelines below are rough targets, not commitments — directional guidance to show the intended pace.

#Where the protocol stands (September 2026)

• Devnet built. The KRAIN devnet has been stood up on our own GPU hardware; it is where protocol features are proven before they reach a public network.
• Verifiable inference demonstrated. The opML fraud-proof flow has been demonstrated end to end across two independent hardware vendors (NVIDIA and AMD): a solver posts an inference result, a watcher re-executes it, and a wrong answer can be challenged.
• On-chain inference demo. An MNIST model is wired through the full devnet cycle (transaction in, inference, result on-chain); a recorded walkthrough is next.
• Contract suite built. The protocol's Stylus contracts build on a current toolchain; deployment of the suite to the Arbitrum Sepolia test network is the next step toward public testnet.

#Launch sequence (the order of events)

Testnet  ->  Mainnet  ->  Snapshot  ->  TGE  ->  Listing

Each milestone must complete before the next begins:

1. Testnet — public testing of the protocol.
2. Mainnet — production launch of the chain.
3. Snapshot — the eligibility snapshot for distribution; the snapshot date is announced after mainnet launches, through official channels.
4. TGE — token generation and distribution; $KRAIN becomes spendable on supported apps (no market/price at this stage — see §5.9).
5. Listing — a primary exchange listing, conditions-gated with no committed date, once utility-driven demand supports a fair opening value.

Dates for each milestone are announced through official channels, not pinned in this document.

#Phases

**Phase 0 — Foundation — now.** Protocol architecture finalized. Core contracts implemented and under test. Solver node operational with GPU support. Open-source repositories live. This whitepaper. Strategic partnerships and grant applications in progress.

**Phase 1 — Testnet — next. Public testnet at testnet.krain.ai. SDK alpha (TypeScript) and SDK beta (Python). Developer documentation. Incentivized testnet program. First wave of agent template launches. The testnet has both developer and non-technical community participation paths** — you do not need a programming background to take part in community testnet activities.

Phase 2 — Developer adoption. Developer grant program funded from the ecosystem allocation. Framework integrations (LangChain, CrewAI, ElizaOS, and other widely-used agent stacks). First hackathon. Ambassador program expansion. Preview of the "Build to Earn" retroactive rewards model.

Phase 3 — Mainnet and TGE. Mainnet launch. $KRAIN TGE via the distribution process described in §5. Staking live. x402 settlement live. "First $1,000" builder program (post-funding deployment, details in agent-templates-spec.md). (The TGE date is announced through official channels once mainnet is live.)

Phase 4 — Growth. Primary and additional exchange listings as conditions support them (see §5.9). Permissionless solver node set. DAO governance transition. Conference presence. Retroactive Builder Rewards program (Optimism RetroPGF-inspired).

Phase 5 — Maturity. Decentralized sequencer. Cross-chain agent operations. Full DAO governance. Tier-1 exchange listings.

Phase numbering and order are firm; timing depends on security review, audit timelines, and partnership readiness. Exact dates are confirmed in formal release notes rather than in this document.

#7. Open Source and Governance

KRAIN is being built as an open ecosystem.

Core repositories. The agent SDK, node implementation, CLI, example agents, and contract source are public. Licenses are MIT for SDKs and templates and Apache 2.0 for the contract suite. AIVM internals are released under BSL 1.1 with a scheduled conversion to Apache 2.0 within 24 months, following the BSL pattern used by other infrastructure projects to balance early protection with eventual open access.

Governance evolution. Governance starts with a benevolent-dictator model under the founding team and a small core committers group. A Technical Steering Committee is added once the protocol stabilizes. Full DAO governance is the destination once the validator and solver sets are decentralized enough to make governance attacks impractical.

Governable parameters. Sequencer margin range, protocol/sequencer revenue split, revenue routing percentages (staker pool, buyback, treasury), IAO bonding-curve parameters, grant release schedule, and emergency circuit breakers are all DAO-controlled with timelocks (48-hour for routine changes, longer for treasury deployments and protocol upgrades).

Project ownership and funding. KRAIN is operated by its core team and is bootstrapped to date, currently raising a pre-seed round. Fundraising progress is shared through official channels rather than fixed in this document.

#8. Risks, Disclosures & Legal

#8.1 Risk factors

Regulatory uncertainty. Token classification, staking treatment, and airdrop/distribution rules continue to evolve in major jurisdictions. $KRAIN is designed and intended as a utility and governance token for use within the KRAIN ecosystem. It is not a security and is not offered as one. Final terms are subject to legal review. The legal and regulatory status of blockchain technologies and tokens varies by jurisdiction and is subject to change; future regulatory action may affect the use, value, transferability, or availability of $KRAIN. It is each participant's responsibility to ensure compliance with the laws and regulations applicable to them.

No market and no market price at TGE. $KRAIN launches spend-first. At the Token Generation Event (TGE) the token is generated and distributed and becomes usable on supported apps and services; at TGE there is no exchange market and no market price. Any market for $KRAIN — and therefore any market price — would arise only at and after a future, conditions-gated listing event that may or may not occur. Where any value does arise, it may be highly volatile and may fluctuate significantly, and the token may have little or no market value. Schedules, listing windows, and the existence of any secondary market are targets and possibilities, not guarantees (see §5.9).

Smart-contract and technology risk. Blockchain technology is inherently subject to risks including network failures, congestion, smart-contract bugs, vulnerabilities, exploits, hacking, denial-of-service attacks, and fraud. All contracts are intended to be audited by qualified firms prior to mainnet, and bug bounties will run continuously, but no audit eliminates all risk. Transactions on-chain are generally irreversible. Participants are solely responsible for securing their wallets, private keys, and seed phrases; lost, stolen, or compromised tokens or credentials cannot be recovered or replaced by the project.

Solver and centralization risk during bootstrap. Early phases run a permissioned solver set and KRAIN-aligned operators for the sequencer, validator, and solver roles to ensure performance and stability. The decentralization roadmap (Phases 4–5) is explicit and committed but not yet delivered; opML is in development / on devnet, not a production mainnet system. Users and developers should weight current centralization appropriately in their risk model.

Market, timing, and project risk. Mainnet timing, exchange listings, and bridge openings depend on conditions outside the project's control. The success, functionality, performance, and continued operation of the KRAIN platform, protocol, and token are not guaranteed. Competing platforms, technological change, business challenges, lack of adoption, or development delays could reduce or eliminate the utility or value of $KRAIN. Participants assume all such risks and accept the potential for total loss.

Tax. Participants are solely responsible for determining and satisfying any tax obligations arising from receiving, holding, using, or transferring $KRAIN or any benefit, in any jurisdiction. The project does not provide tax, legal, or financial advice and recommends consulting qualified professionals.

#8.3 Forward-looking statements

This Document contains forward-looking statements — including projections, goals, roadmaps, timelines, allocations, mechanisms, and anticipated outcomes. Several parameters are explicitly marked as open and will be set later (for example, the headline community allocation percentage, the Season 1 / Season 2 split, the XP-to-token conversion, and certain tier thresholds). All such statements are speculative and subject to significant risks and uncertainties; actual results may differ materially. Schedules are targets, not commitments. The Issuer undertakes no obligation to update forward-looking statements except as it may choose to do through official channels.

#8.4 No investment, legal, financial, or tax advice

Nothing in this Document, and nothing said by any contributor, team member, agent, moderator, ambassador, or other person, constitutes investment, financial, legal, accounting, or tax advice or a recommendation to acquire, hold, or dispose of any digital asset or other product. Any analysis, commentary, or output produced by KRAIN AI agents is informational only and inherently may contain errors or omissions; use it at your own risk. Conduct your own research and consult qualified professional advisors before making any decision. You are solely responsible for your own decisions and any resulting gains or losses.

#8.5 Eligibility, jurisdiction & compliance

Participation in KRAIN programs (including any airdrop, giveaway, sale, or distribution) is limited to eligible persons and is void where prohibited. By participating you represent and warrant that you are of legal age and capacity; that you are not a U.S. Person and not a resident, citizen, or person located in any prohibited or comprehensively sanctioned jurisdiction (including, without limitation, jurisdictions subject to OFAC or comparable sanctions); and that you are not a Restricted Person on any applicable government, sanctions, or watchlist. The project may use geo-location, IP, and other checks and may require identity, residency, source-of-funds, or other documentation for KYC/AML/CTF compliance; circumventing geographic restrictions (e.g., via VPN/proxy) or providing false information may result in disqualification and forfeiture. The project may refuse, suspend, modify, or terminate participation, and void participation by prohibited persons, at its discretion and to the extent permitted by law.

#8.6 Nature of $KRAIN distributions — discretionary, non-monetary, no entitlement

This subsection governs all $KRAIN distributions, including distributions to people who were promised or allocated tokens (contributors, role and key holders, early supporters, and the community).

• No monetary value; not compensation. $KRAIN tokens carry **no guaranteed monetary value, are

not redeemable for fiat, and are not compensation, wages, salary, or a payment denominated in any currency or owed in any amount. Any reference to a token amount, points total, tier, "value," or estimate is informational only and is not a promise of value, payout, or return.** As stated in §5.9 and §8.1, $KRAIN has no market and no price at TGE.

• Discretionary distribution. Whether, when, to whom, and in what amount any $KRAIN is issued

or distributed is at the project's sole and absolute discretion; the project may modify, substitute, delay, condition, or decline to make any distribution, and may elect not to issue any token at all, to the extent permitted by law and consistent with its published terms.

• No equity, security, ownership, or entitlement. Receiving, being promised, or being allocated

$KRAIN confers no equity, ownership, profit-sharing, dividend, security, or investment-contract right, and no entitlement or vested claim to any token, amount, or benefit. Tokens are a utility asset, tradeable only if and when a listing occurs (§5.9), acquired and used for utility and not as an investment, with no expectation of profit. Distributions require no purchase or payment (other than any applicable gas or third-party fees, which are the recipient's responsibility) and confer no consideration-based right.

• Discretionary recognition, not an obligation. Where the project recognizes contribution or

support with $KRAIN, such recognition is a discretionary, contribution-based distribution — not a debt, wage, or sum owed — and is subject to the published Contributor & Ambassador Terms and the no-oral-promises and entire-agreement provisions in §8.7.

#8.7 Binding terms control; contributor status; no oral promises

This whitepaper is a high-level description — it is not a contract and not the project's binding legal terms. Participation in any KRAIN program is governed by the project's separately published, counsel-reviewed terms, which control in case of any conflict with this Document:

• Terms of Service — general terms governing use of KRAIN sites, apps, and services.
• Privacy Policy — what data is collected and how it is used, retained, and disclosed.
• Airdrop Terms — eligibility and prohibited-jurisdiction exclusions; AML/KYC; risk

acknowledgements; "as is" / no-warranty and no-market-value language; limitation of liability (capped, e.g., at gas fees incurred); indemnification; binding individual arbitration; class-action waiver; one-year limitation period; force majeure; amendment and severability.

• Founders Key Terms — Founders Key NFT sale and benefits; **"acquired for use, not investment;

no expectation of profit"; no equity/IP transfer; eligibility/KYC and U.S./sanctioned-person exclusion; "as is" / no-warranty; limitation of liability (capped at amount paid); release; binding arbitration; jury-trial waiver; class-action waiver; the project's discretion to modify, substitute, or delay benefits; no oral information or advice creates any obligation.**

• Giveaway Rules — sweepstakes terms; "no purchase necessary"; eligibility/age/KYC;

non-transferable, no-cash-redemption prizes; value-change disclaimer; release and limitation of liability; arbitration and class-action waiver; publicity consent.

• AI Agent Terms — agent outputs are informational, not investment advice, "as is," no

warranties, limitation of liability, indemnification, acceptable-use and IP terms.

• Promoter & Ambassador Terms — promoter obligations; disclosure/compliance; IP licensing;

confidentiality; anti-bribery; force majeure; fee-capped liability; and independent-contractor status (no employment, agency, partnership, or joint venture).

• Contributor & Ambassador Terms (new for v2.1) — see below.

Contributors are independent contractors. All contributors, ambassadors, moderators, creators, freelancers, contractors, and other persons who provide services to or for KRAIN ("Contributors") do so solely as independent contractors. Nothing in this Document, and nothing in any contribution, role, title, reward, points balance, or token allocation, creates an employment, agency, partnership, joint-venture, or employer-employee relationship. Contributors are not entitled to wages, salary, benefits, or employment protections, are responsible for their own taxes and any applicable invoicing, and set their own means and methods of work. Any compensation, where offered, is only as separately and expressly agreed in writing.

No oral promises; only signed writings bind. No statement, representation, promise, estimate, or assurance — whether made verbally or in Discord, Telegram, direct message, social media, email, or any other channel, and whether made by a founder, officer, contractor, moderator, ambassador, or any other person — creates any binding obligation, token entitlement, allocation, or guarantee. Only terms set out in a written agreement signed by an authorized representative of the project are binding. Any prior or contemporaneous oral or written understanding regarding token allocations, rewards, recognition, or compensation is superseded by, and has no force except to the extent expressly set out in, such a signed writing.

#8.8 Living document; revisability; copyright

This Document is a living specification and a work in progress. Token parameters, allocation details, mechanisms, and timelines are subject to refinement based on legal review, audit findings, and community input, and several parameters remain explicitly open (see §8.3). The Issuer reserves the right to modify this Document and any program at any time, without notice, to the extent permitted by law; the published binding terms govern the effect of any changes on participants. The contents of this Document are Copyright © 2026 KRAIN. All rights reserved.

#9. Summary

KRAIN combines three things that no other AI x crypto project has assembled into one stack: a live consumer product with an existing user base, an AI-native L2 with verifiable inference, and a fixed-supply token whose value accrues from real protocol revenue rather than from speculative narrative.

The marketplace is operating today. The protocol is in pre-mainnet engineering. The token's economics are designed so that every unit of inference, every agent-to-agent payment, and every agent launch contributes mechanically to $KRAIN value accrual through fee-funded buybacks and real staking yield — value is made, not allocated.

The remainder of the work is execution.

#Help shape the next revision

This whitepaper is a work in progress, and the next revision will reflect what the community and our partners tell us. The open questions we most want your read on are the ones still marked open above: the headline community allocation percentage, the Season 1 / Season 2 split, and the XP-to-$KRAIN conversion approach.

Head to the dedicated feedback channels and tell us what you think. Every voice counts, and we will adjust as the input warrants.

#Appendix A — Changelog

This changelog summarizes what changed between major revisions of the KRAIN whitepaper. It is written for readers, not engineers: it covers substance, not formatting. Specific parameters and timelines remain subject to refinement; nothing here is an offer to sell securities.

• V1 — original GitBook whitepaper (krain.gitbook.io/krain).
• V2 (v2.0) — full rewrite, published 2026-05-30.
• v2.1 — current revision, 2026-06-21, folding in community and partner feedback.

#V1 → V2

V2 is a ground-up rewrite. V1 described a consumer AI-app platform (portal, token launchpad, app hosting) with an unspecified token. V2 repositions KRAIN as a three-layer stack — live marketplace, AI-native L2 protocol, and a fully specified token — and replaces "to be announced" tokenomics with a complete economic model.

Added

• The KRAIN Protocol — an entirely new layer: an AI-native, EVM-compatible optimistic-rollup L2 that settles to Ethereum, with a dual EVM + WASM (Stylus) runtime.
• AI Virtual Machine (AIVM) — tensor precompiles (matmul, activations, conv2d, attention) so AI execution can be expressed directly in contract code.
• Smart Agents — on-chain agents with their own contract, wallet (ERC-6551), identity (ERC-8004), and optional content provenance (ERC-7007), deployable via an AgentFactory.
• Optimistic Machine Learning (opML) — verifiable off-chain inference with solver bonds, a challenge window, and a bisection fraud-proof game.
• x402 Payment Gateway — HTTP-native agent-to-agent micropayments with a 0.05% agent tax.
• Inference Router — reputation-and-cost-aware routing of inference requests to solvers.
• Full tokenomics (V1 said "to be announced"): fixed 1,000,000,000 $KRAIN supply; a six-bucket distribution (Ecosystem 30%, Treasury 25%, Team 18%, Investors 15%, Community 8%, Liquidity 4%); vesting schedules; and three revenue streams (sequencer margin, agent tax, IAO fee).
• Revenue routing / buyback flywheel — fixed 20% staker pool (paid in ETH) / 40% buyback-and-burn / 40% treasury split.
• Staking for real protocol-fee yield in ETH, with governance weighting.
• Quest multipliers — holding-tier point boosts (None → Protocol).
• Anti-dump design — two-season airdrop, activity-gated vesting, staking opportunity cost, bridge rate limits.
• Open-source & governance section — public repos, licensing (MIT/Apache/BSL), and a path from benevolent-dictator to full DAO.
• Risks & Disclosures section.
• Living-draft / community-feedback framing with dedicated Discord and Telegram channels.

Changed

• Positioning: "infrastructure for the AI economy" is retained, but the three pillars shift from App Portal / Token Launch System / App Hosting to Marketplace / Protocol / Token.
• AI App Portal → KRAIN Marketplace: the searchable directory, reviews, ratings, categories, ambassador and creator programs all carry forward, now framed as the live product layer feeding the on-chain economy.
• Token Launch System → IAO Factory: the bonding-curve launch model is retained and generalized into a single permissionless launchpad; agent tokens graduate to a Uniswap V3 pool with a permanently locked LP NFT.
• Liquidity model: V1's "Guaranteed Liquidity Pools (5-year lock)" are replaced by IAO graduation into a permanently locked LP — a stronger lock by a different mechanism.
• Deployment story: V1's standalone "App Hosting" product is reframed as Smart Agent deployment plus the solver/inference infrastructure.
• Token utilities: governance, staking, buyback/deflation, and performance rewards all carry forward in stronger form (real-fee yield, mechanical buyback).

Removed

• The "KDEX" token and Infinite Liquidity Pools (ILP). KRAIN consolidates to a single token ($KRAIN); the second token and the ILP mechanism are dropped.
• Tiered launch packages (Social / FastPass / VIP). Replaced by one permissionless, formula-driven IAO bonding curve with no privileged tiers.
• "Orion Protocol" naming. The agent-autonomy concept survives as Smart Agents; the brand name is dropped.
• Time-bound operational program details (specific airdrop point values, monthly ambassador-mission rewards, honor-system dates) — these live in program terms, not the whitepaper.

#V2 → v2.1

v2.1 is a feedback-driven revision, not a rewrite. The technical architecture (§4) is essentially unchanged. The changes concentrate on the token, distribution, vesting, and launch sequence — the areas the community and partners pushed hardest on — and on plain-language clarity. A visible "You said → we changed" summary near the top of v2.1 maps community asks to changes.

Added

• "You said → we changed" summary — a top-of-document changelog crediting named community contributors and partners.
• TGE-vs-listing separation (new §5.9, "utility first"). A major structural clarification: at TGE, $KRAIN is generated, distributed, and spendable on supported apps, with no market and no price; a primary exchange listing comes later and is conditions-gated, with no committed date. This carries the "value is made, not allocated" thesis.
• "Total community picture" explainer (§5.2). The 8% direct airdrop is not the whole of what the community receives — community members and contributors also draw from the 30% Ecosystem & Developer Fund and from contributor recognition.
• Plain-language definitions for "AI-native L2" (§4) and "bonding curve" (§4.5), for non-technical readers.
• Demand-driver callout (§5). Names the mechanisms that create sustained demand beyond staking and governance (spending on apps, IAO fees, x402 routing, solver collateral, buyback).
• Traction and funding lines (§1). Engagement-led traction framing (150,000+ community), and a statement that KRAIN is bootstrapped to date and currently raising a pre-seed.
• Key Holder / Founders Key recognition (§5.2). Confirms the commitment is honored; exact mechanics to be finalized through official channels.
• Eligibility, anti-farming, account-linking, KYC, and jurisdiction guidance (§5.2). One place answering the recurring questions: quality-over-volume eligibility, wallet-based accrual across Origin/Intract Alpha/Catalyst, support path if account-linking fails, Solana→EVM mapping, conditional KYC, and a prohibited-jurisdiction list to be published ahead of distribution.
• Phase-weighting transparency and Discord-role recognition (§5.2). Earlier phases weighted more; both time-and-effort and capital contribution recognized; earned roles (Ambassador, OG, Kartel) recognized within the contributor framework.
• Launch-sequence overview (§6): Testnet → Mainnet → Snapshot → TGE → Listing, each milestone gating the next, with the snapshot announced after mainnet.
• "Legal & Terms" pointer (§8). States the whitepaper is not the binding legal surface and points to the Terms of Service, Privacy Policy, Airdrop Terms, Founders Key Terms, and Contributor & Ambassador Terms.
• Testnet accessibility note (§6). Both developer and non-technical community participation paths.

Changed

• Team & founder vesting → milestone-based. Replaces the V2 calendar vest (12-month cliff, 25% at month 13, linear tail) with a milestone-gated release: a hard floor of no team release before mainnet, then tranches unlocked by real protocol milestones (mainnet live → TGE → supported apps integrated and spending $KRAIN → sustained protocol revenue → primary listing). Total allocation unchanged at 18% / 180M.
• Vesting trust hardening (§5.3). Community-airdrop vesting (25% at TGE, 75% over 6 months) is now stated up front, held in audited smart-contract custody (not a team wallet), with "active" clearly defined (ordinary app use, not gas-paying or task-grinding), an inactivity window widened from 30 days to 60–90 days, no claim-slashing, and a named fate for unclaimed tokens (Season 2 loyalty pool or burn).
• Timing is milestone-gated (replacing the "late summer / summer" phrasing): each phase starts when the previous one is complete, and dates are announced through official channels, not pinned in this document.
• Listing language throughout (§5.6, §5.10, §6) tied to the listing event rather than TGE, consistent with the new utility-first sequence.
• Ecosystem-fund first-six-months release clarified as monthly-linear (~6.7M/month).
• Liquidity allocation repurposed for market-making at the listing event (was "at TGE").
• opML framing. Explicitly described as in active development and on devnet — not a production mainnet system (§4.4, §8).
• Anti-dump section (§5.10) reorganized around the new vesting, milestone-gated team release, and utility-first launch, and adds that community allocation is not pooled with or competed against any exchange-listing allocation.

Removed

• The "selling Season 1 tokens reduces Season 2 eligibility" mechanic. The most-criticized anti-dump rule from V2 is removed; sell-pressure management now relies on vesting and staking opportunity cost instead.

Still open (called out in v2.1)

• The headline community allocation percentage, the Season 1 / Season 2 split, the XP-to-$KRAIN conversion ratio, certain quest-tier thresholds, and the $KRAIN smallest-sub-unit name remain explicitly open and will be set with the community ahead of the snapshot.

Version v2.1 — Working draft, 2026-06-21. This document is a living specification and is provided for informational purposes only. It is not a contract and not the project's binding legal terms; the separately published, counsel-reviewed terms (linked from the krain.ai footer) control. Nothing in this document constitutes an offer to sell securities, an offer of any regulated financial instrument, or investment, legal, financial, or tax advice. $KRAIN is a utility and governance token with no guaranteed monetary value and, at TGE, no market and no market price (§5.9). Several parameters (headline community allocation percentage, Season 1 / Season 2 split, XP-to-token conversion, and certain tier thresholds) remain explicitly open and will be set ahead of the snapshot.
