EIP-712-signed risk attestation, verifiable OFFLINE in one step — no trust in this server required. Perishable (10-min) proof of the BTC/ETH risk regime (calm | elevated | crash) from GBLIN's on-chain Crash Shield on Base. Consumed daily by a third-party ERC-8004 agent as a pinned input of its decision rule. FREE sample: GET /api/x402/attestation-sample. Free verifier: verify_risk_attestation in @gblin-protocol/mcp-server.
AI Action Receipts: seal the HASHES of an AI action (input/output as hashes; your action label + meta are published) into GBLIN's signed append-only transparency log. Portable receipt: Ed25519 signature + RFC 6962 inclusion proof + C2SP signed checkpoint; root anchored daily on Base (EAS). Proves existence and time — not a compliance certificate. Free reads + demo: gblin-mcp.gblin-mcp-worker.workers.dev/log. Offline verifier: github.com/gblinproject/gblin-treasury-risk-regime
