Registry addresses

Not started. The Agent / ERC-8004 product track is not started. These pages are retained for reference only. Do not treat register/browse copy below as a shipped CanHav product commitment.

Base Sepolia (chain ID 84532). CanHav does not own these contracts. Confirm on Blockscout.

Configured testnet registries

Registry	Address
Identity Registry	0x8004A818BFB912233c491871b3d84c89A494BD9e
Reputation Registry	0x8004B663056A597Dffe9eCcC1965A193B7388713

Identity Registry deploy block (indexer start): 36304145.

Safety: vanity prefix

Network	Identity prefix
Base Sepolia	0x8004A818
Mainnet	0x8004A169

Every CanHav layer (site banner, verify script, agents indexer startup) refuses an Identity Registry address that does not start with 0x8004A818. If you see a configuration error about the prefix, you almost certainly pointed at mainnet by mistake.
