AI-Powered Autonomous Payments for Open-Source Contributors
GrantBot is an autonomous payment agent that monitors GitHub repositories for merged Pull Requests and instantly pays contributors in USDC — without any manual approval, invoicing, or wallet popups.
How It Works
Maintainers register their repo and define payout rules (e.g., 5 USDC per merged PR, with a daily spending cap).
MetaMask Smart Account delegation is granted once via ERC-7715 — giving GrantBot permission to spend within set limits, without ever holding the maintainer's private keys.
When a PR is merged, a GitHub webhook fires, and Venice AI reasons about the event — checking contributor eligibility, payout rules, and spending caps — then decides whether and how much to pay.
If approved, 1Shot's Permissionless Relayer executes the USDC transfer on-chain via EIP-7710, with gas abstraction handled automatically — no signup, no pre-funded paymaster.
Contributors get paid within seconds of their PR being merged — fully autonomously.
Why It Matters
Open-source maintainers want to reward contributors quickly, but manual payouts are slow, awkward, and often forgotten. GrantBot turns "merged PR" into "instant payment" — a real-world demonstration of agentic Web3 in action.

Fundraising Status
GrantBot is currently self-funded and built as part of the MetaMask Smart Accounts Kit x 1Shot API x Venice AI Dev Cook-Off hackathon. We are not currently raising external funding. If GrantBot gains traction with open-source maintainers post-hackathon, we would consider pre-seed funding to expand support for multi-chain payouts and additional automation features.
