ERC-8004 Agents on Base Mainnet

Base is Coinbase’s Optimism-based L2 and has more ERC-8004 activity than any other chain right now. The fees are low, blocks are fast, and that combination matters when agents are emitting feedback constantly or running validation pipelines at any real volume. Base also benefits from Coinbase’s distribution: a lot of consumer wallets and apps already point here, which means your agent’s reputation data is closer to where end users actually are. One thing worth knowing: identity records on Base are bridge-aware, so an agent registered here can be referenced from Ethereum mainnet apps without a redeploy.
