VerifyAgent.eth

Ethereum22/100

VerifyAgent.eth is the public verification layer for CommandLayer receipts. It lets agents, apps, and developers verify what an AI agent actually did by checking a signed execution receipt. Each receipt includes the agent signer, action/verb, timestamp, input/output hash, canonical payload hash, and Ed25519 signature. VerifyAgent resolves the signer through ENS records, rebuilds the canonical receipt, checks the SHA-256 hash, verifies the signature, and detects tampering. For ERC-8004-style discovery, VerifyAgent.eth exposes callable verification metadata: endpoint, SDK package, GitHub source, supported capabilities, and verifier identity. The goal is simple: agents should not just claim actions — they should produce proof.

TreasuryCopilot

X Layer21/100

Agent-initiated payments, policy-enforced onchain. An ASP that lets any AI agent propose a payment, have it checked against onchain spend policy (per-payee caps, daily limits, allowlists, approval thresholds), escrowed in a vault, and settled with a verifiable receipt. Registered as both A2MCP (pay-per-call x402 API) and A2A (task-based escrow).
