RelAI
An ETHGlobal project with a team of five: a decentralized reputation registry for AI agents, so trust is portable instead of trapped in one vendor’s dashboard.

The problem
Once agents can pay and act, you need more than a chat log. You need a record of who the agent is, what it has done, and whether that record can be trusted outside one company’s database. Off-chain scores are easy to fake. Cloned identities are easy to spin up.
RelAI is our attempt at a registry: reputation anchored on-chain, payments attached, governance in the plan. I built this with a team of five at ETHGlobal. The screenshot above is a conceptual registry UI for the idea, not a live production console.
What shipped in the hackathon
ReputationManager.soldeployed on Hedera as the canonical registry.- x402 payments so agents can settle microtransactions instead of sharing API keys.
- Coinbase Wallet integration for custody and user-to-agent or agent-to-agent interaction.
- DAO governance, Chainlink Functions, and cross-chain sync were designed, not finished. Those are still on the roadmap.
How I talk about it
Foreman answers “is this agent allowed to act as this user, right now?” RelAI answers “which agent is this, and what is its track record?” Together they are the two controls I want in any agent platform: identity at action time, and a registry you can certify, pause, or slash.
That mapping is spelled out in the ADLC write-up.
