All Agether contracts are deployed on Base mainnet (chain ID 8453). ERC-8004 identity contracts are also available on Sepolia for testing.

The ERC-8004 IdentityRegistry address uses the 8004 prefix intentionally — this is a convention of the ag0 identity standard.

Using Addresses in the SDK
The SDK has all Base mainnet addresses baked in. You don’t need to specify them for production:
import { MorphoClient } from '@agether/sdk';
// No addresses needed — Base mainnet defaults are built in
const morpho = new MorphoClient({
privateKey: process.env.AGENT_PRIVATE_KEY!,
rpcUrl: 'https://base-rpc.publicnode.com',
agentId: '17676',
// chainId defaults to 8453 (Base)
});
contracts config:
const morpho = new MorphoClient({
privateKey: process.env.AGENT_PRIVATE_KEY!,
rpcUrl: 'http://localhost:8545',
chainId: 31337, // Hardhat
contracts: {
agether4337Factory: '0xYourLocalFactory',
agether8004Scorer: '0xYourLocalScorer',
erc8004ValidationModule: '0xYourLocalValidator',
agetherHookMultiplexer: '0xYourLocalHook',
identityRegistry: '0xYourLocalIdentity',
morphoBlue: '0xYourLocalMorpho',
usdc: '0xYourLocalUsdc',
},
});
