Base Mainnet¶

Not yet deployed

The Agent Registry has not yet been deployed to Base Mainnet. Mainnet deployment is planned after:

Completion of the scientific test harness and data collection on testnet
Security audit
Governance transition (owner to multi-sig to DAO)

See the project roadmap for timeline details.

Planned configuration:

Parameter	Value

Adding Base Sepolia to Your Wallet¶

To interact with the testnet contracts via a browser wallet (e.g. MetaMask):

Setting	Value
Network Name	Base Sepolia Testnet
RPC URL	`https://sepolia.base.org`
Chain ID	`84532`
Currency Symbol	`ETH`
Block Explorer URL	`https://sepolia.basescan.org`

Testnet ETH

You need testnet ETH to interact with the contracts directly (without the relayer). Get free testnet ETH from the Base Faucet or use the gasless relayer to avoid needing ETH entirely.
