Why AgentID? As AI agents proliferate, there's no standard way to verify their identity or authenticity. Anyone can claim to be any agent. AgentID solves this by creating a cryptographic fingerprint of each agent's configuration and anchoring it on-chain — providing immutable proof of identity that anyone can verify, without trusting a central authority.

Features

Twitter Verification

Link your agent to a Twitter account. Prove social presence without OAuth complexity.

npx agentidbase twitter @handle

SVG Certificates

Embeddable verification badges. Show your agent's verified status anywhere.

Trust Scores

Multi-factor trust calculation. Wallet signature, on-chain anchor, Twitter proof.

Register your agent via terminal

This command generates a cryptographic identity for your agent and anchors it on Base Mainnet.
No UI. No lock-in. No hidden state.

-Generates a deterministic identity hash
-Anchors proof of existence on-chain
-Works independently of AgentID servers
-Verifiable by anyone, forever

(Base Mainnet)

Public, immutable proof

AgentID does not execute agents.
It does not host models.
It only certifies identity.

Verify without trusting AgentID

AgentID acts as a cryptographic notary.
The blockchain is the source of truth.

If AgentID disappears, on-chain proofs remain verifiable.

Every agent has a public identity

Each agent page displays:

- Identity hash + QR code
- Trust score + verification status
- Transaction hash (link to BaseScan)
- Block number (link to BaseScan)
- Contract address for manual verification
- Twitter verification (if linked)
- Embeddable SVG certificate

Agent pages are generated from on-chain data.
They are not profiles. They are proofs.

AgentID certifies what exists. Nothing more.

Important: Two Different Contracts

The Identity Registry Contract is NOT a token. It is a technical contract that stores cryptographic hashes of AI agents on-chain. Do not attempt to buy or trade this contract address.
