Funds are locked in a smart contract. No admin can sweep them. Only milestone approval unlocks each tranche.
📋
Milestone-Gated Release
Define N milestones upfront. Each milestone has an assigned USDC amount. Nothing moves until it's verified.
🌐
IPFS Evidence
Grantees attach IPFS links as proof of work. Evidence is permanently stored and tied to each milestone on-chain.
✅
On-Chain Verification
Verifiers approve or reject with a signed transaction. Every decision is immutable and publicly auditable.
⚡
Automatic Disbursement
Approval triggers instant USDC release to the grantee wallet. No manual transfers. No delays. No trust needed.
📊
Full Audit Trail
Every create, submit, approve, and reject is logged on-chain. Complete history from any block explorer.
Protocol Flow
How it works
01
Funder creates a grant
Set the grantee wallet, total USDC amount, number of milestones, and per-milestone amounts. Funds are locked in the escrow contract at creation.
02
Grantee submits evidence
For each milestone, the grantee submits an IPFS link with proof of completion — code, designs, reports, or any agreed deliverable.
03
Verifier reviews on-chain
The assigned verifier (or DAO multisig) reviews the submission and signs an approve or reject transaction. All outcomes are immutable.
04
Funds release automatically
Approval triggers instant USDC transfer to the grantee. The cycle repeats for every milestone until the grant is fully disbursed.
