AgentVisa

AgentVisa is a privacy preserving authorisation infrastructure for AI agents and humans

AI agent can prove that it is backed by an approved human and authorised for a constrained action, without revealing the human’s identity. A smart contract checks the proof before funds move.

It works like this:

1. An approved human creates a private identity commitment.

2. AgentVisa adds that commitment to an approved-operator Merkle group.

3. The human delegates a constrained session to an agent.

4. The agent generates a BN254 Groth16 membership and authorization proof.

5. A relayer submits the proof to an immutable gate contract.

6. The gate checks an accepted root, scope, expiry, action limits, and a scoped nullifier.

7. A demo vault executes the permitted action.

8. Replays, expired proofs, retired roots, and over-limit actions fail on-chain.
