GrantOS
GrantOS is the first onchain grant protocol that enforces milestone delivery with cryptographic proofs not trust, not screenshots, not committee opinion. The contract verifies. The code runs.

描述
GrantO is the onchain grant enforcement layer DAOs have needed for years.
Every major DAO distributes millions in grants through the same broken process: funds leave the treasury, a spreadsheet gets posted, and enforcement becomes social. Builders who miss milestones face a forum post. They keep the money.
GrantOS v3 replaces that entirely. When a builder submits milestone proof, they do not paste a URL. They click Generate Proof, Noir ZK Coprocessor genarates the prove against the GitHub API and produces a cryptographic proof that a specific PR exists, is merged, and is authored by the builder's wallet-linked account. The WebProofVerifier contract on Arbitrum One reads that proof in the same transaction. The math either checks out or the transaction reverts.
On top of this: ZK Identity Binding permanently links wallets to verified GitHub accounts Sybil attacks are dead. Proof-Gated Slashing enforces cryptographic due process no onchain warning means no slash possible, enforced at the contract level. Streaming Milestone Payments send USDC per second via Superfluid, builders earn exactly what they earned, to the millisecond. An AI Milestone Verifier writes Gemini verdicts into EAS attestations advisory only, the ZK proof enforces. Builder Reputation Scores are derived entirely from onchain attestation history no admin can touch them.
13 routes. 4 user roles. Live on Arbitrum One today.
本次黑客松进展
GrantOS was built entirely during the hackathon period.
Starting from an empty Next.js directory, we shipped:
- 13 application routes across 4 user roles (Builder, Committee, DAO Admin, Public Observer)
- ZK Proof Milestone Submission — builders generate cryptographic web proofs via Noir ZK Coprocessor. The smart contract verifies the proof onchain in the same transaction. No human reads anything.
- ZK Identity Binding — one-time permanent cryptographic link between a wallet address and a verified GitHub account. Deployed to GrantIdentityRegistry.sol on Arbitrum One.
- Proof-Gated Slashing — committee members cannot slash without a 24-hour onchain warning EAS attestation. WarningRequired() enforced at the contract level.
- Streaming Milestone Payments — approved milestones stream USDC per second via Superfluid. Cancellable and slashable at any point.
- AI Milestone Verifier — Gemini reads PR diffs and writes verdicts into EAS attestations. Advisory only.
- Builder Reputation Score — tamper-proof onchain score derived entirely from EAS attestation history. Zero admin control.
- Full treasury dashboard, notification system, and public grant explorer no wallet required.

融资状态
Bootstrapped. No external funding raised.
GrantOS was built independently during the hackathon with no venture backing, no grants received (ironic), and no outside capital. The project is self-funded by the founding team.
We are actively exploring grant opportunities from Arbitrum and the Ethereum Foundation given the direct alignment with their grant program infrastructure needs. GrantOS solves a problem every major DAO faces today and the tooling (Noir ZK Coprocessor, EAS, Superfluid) is live on Arbitrum right now.
Open to conversations with DAOs looking to replace spreadsheet-based grant enforcement with cryptographic proof verification.
