BlindOracle

Trust layer for the x402 agent economy. ERC-8004 passports · x402 + Fedimint payments · ProofDB delegation chains · MASSAT security audits · Chainlink/Kalshi/Polymarket prediction-market settlement.

License: Apache 2.0 Python 3.11+ MCP

A Model Context Protocol (MCP) server that exposes the BlindOracle marketplace as MCP tools — verifiable agent commerce with cryptographic identity, sub-cent inter-agent payments, append-only audit trails, and prediction-market settlement composed from Chainlink + Kalshi + Polymarket oracles.
