Base Mainnet registration fails: missing Identity Registry mapping for chainId 8453

[bencbernstein]

Thanks for building this :)
I ran into an issue when trying to register an agent on Base Mainnet or Sepolia (chainId 8453).

❌ Error

When running:
npm run register

with Base Mainnet RPC:
RPC_URL=https://mainnet.base.org
OR
RPC_URL=https://sepolia.base.org

I get:

Registration failed: No identity registry address for chain 8453
