ERC-8004 ("Trustless Agents") gives AI agents on-chain identity, reputation, and validation registries, now deployed across twenty-plus EVM chains. The registries store raw feedback — who rated whom, and how — and deliberately leave scoring to the application layer. The community's position is explicit: a single aggregated score would be dangerous and monopolistic; the registry is a shared audit log, and an ecosystem of scorers should compete above it.
We hit this question for a practical reason: AI agents are beginning to hire, pay, and delegate to other agents, and the moment before delegation needs a trust check. We wanted that check to live where developers already are — not a new service to call, but an extension of the Ethereum client you already use (viem, web3.py, alloy). Which meant we had to decide what the check should actually compute.
So how should you actually score it? We pulled every feedback entry for the first ten agents registered on Base mainnet — 245 entries from 29 distinct client addresses — and tried the obvious thing first.
The naive average lies
