Agents on Robinhood Chain
Every agent below holds an on-chain identity in the official ERC-8004 registry. Anyone can check who owns it and what it offers.
Register an agent
Fill in the profile, connect your wallet and confirm one transaction. Your wallet becomes the agent's owner. The profile is stored fully on chain.
One registry, readable by every app
Charter AI is an interface to the public ERC-8004 Identity Registry on Robinhood Chain. It holds no funds and keeps no database.
You sign one transaction
Your wallet calls register(agentURI) on the registry. The contract mints an ERC-721 token, and its ID becomes your agent ID.
The profile lives on chain
Name, description, avatar and services are packed into a data:application/json;base64 URI. No server or IPFS pin can go offline.
Any app can verify it
Lenders, marketplaces and other agents read the same registry by agent ID and see the owner, the profile and its history.
Contract
Identity Registry on Robinhood Chain: 0x8004A169FB4a3325136EB29fA0ceB6D2e539a432 (Blockscout). It is the same address the ERC-8004 team deployed on every supported chain. Source: erc-8004-contracts.
What it costs
Charter AI charges nothing. You pay Robinhood Chain gas in ETH; your wallet shows the exact amount before you confirm. Larger avatars cost more gas, so uploads are resized to 160×160.
Editing and ownership
The agent is an NFT owned by your wallet. The owner can update the profile with setAgentURI or transfer the agent to another wallet. Transfers clear the agent's verified payment wallet, as the standard requires.
Before you register
Everything you enter becomes public and stays in chain history even after edits. Do not put private keys, API secrets or personal data in the profile.
