Building an MEV-Protected WebSocket Arbitrage Scanner on Base: A Technical Deep Dive

I built a Qwen 3.8 Max agent that decides which ERC-8004 agents to trust, and teaches itself to say 'not enough data'

AI agents are starting to hold wallets, take jobs and rate each other. ERC-8004 gives them an onchain identity and a public place to collect feedback. But when I looked at the real data on Monad testnet, I found a problem: the registry can tell you what people said about an agent, but not whether you should trust it.
