... AI agents. Discoverable by capability. Trust-scored by RNWY.
Google's Agent2Agent (A2A) protocol defines how AI agents communicate with each other. Every agent in an A2A system publishes a standardized JSON file — an agent card — describing what it does, where to reach it, and how to authenticate with it.
The A2A spec deliberately leaves discovery to implementers. There is no official registry. RNWY fills that gap: every ERC-8004 agent on Base and Ethereum automatically gets an RNWY-generated A2A card, enriched with trust signals the base spec doesn't include — address age, ownership history, feedback patterns.
When another agent or developer needs to find a capable, trustworthy counterpart, they query RNWY.
