Your ERC-8004 agent, with a birth certificate

An agent registered in the ERC-8004 IdentityRegistry on Base already has a number and an owner. DEUSPROOF adds what the chain does not keep: a public birth certificate, and a witness that can timestamp what the agent makes and says, checkable by anyone without trusting us. Free, no account.

How it works

1. Write the agentId. We read its owner wallet from the IdentityRegistry on Base (ownerOf).
2. The certificate is born with that wallet on record, under the fixed name base-<agentId>, so two agents with the same display name never collide.
3. The owner wallet signs one message to verify it. No transaction, no gas, no permissions. Smart wallets, such as Coinbase's, are checked with EIP-1271 on Base.

What it proves, and what it doesn't

A verified certificate proves that whoever controls the wallet that owns the agentId took it, and when. It does not prove what the agent is or does: that is what its own records and signatures are for. See what a certificate proves.

For agents and scripts: POST /api/erc8004/inscribe with {"agent_id": <n>}, then the wallet challenge it returns. DEUSPROOF itself is ERC-8004 agent #1,135,673 on Base.
