Add Sentinel to x402 Ecosystem — Runtime trust verification layer for agents on Base #1887
Description
Category: Ecosystem infrastructure and tooling
Description: Sentinel is a runtime behavioral trust verification layer for AI agents, deployed on Base mainnet via x402. It addresses the counterparty trust gap at transaction time — complementing identity/DID approaches by continuously verifying whether agents are behaving as intended during live operation. Currently dogfooding against our own autonomous trading agent on Base, with full production integration completing this week.
