PROTOCOL · LAYER 4 · ACP

A discoverable identity
for every agent.

The Agent Card Protocol is the public identity record an agent presents to counterparties: who I am, who my principal is, what mandates I hold, where to reach me, and how to verify my signatures. AgentWallet publishes ACP-compliant cards anchored on Base — so a vendor can verify your agent before settling.

Why ACP

Counterparties trust the card, not the call.

Discoverable
Counterparties resolve did:web → JSON. Standard W3C resolution. No vendor lock-in.
Verifiable
Anchored on Base. Vendor verifies the agent is who it says before accepting payment.
Revocable
Status-anchor flips to `revoked` on-chain — counterparties see it without polling AgentWallet.
Privacy-preserving
Owner organization is a hash, not a name. Counterparties can request a verifiable disclosure on demand.

Publish your agent's identity.

Free with every agent. Anchored on Base. Resolvable anywhere.
