Ivo Shemi integrated the OIXA Protocol into the google/A2A repository, enabling autonomous hiring and payments between AI agents with on-chain guarantees. He focused on protocol integration and documentation, outlining the protocol stack—including COMMS (A2A + MCP), PAYMENT (x402), and REGISTRY (ERC-8004)—and detailing secure interactions on Base Mainnet using USDC. His work included implementing on-chain escrow, reverse auctions, cryptographic output verification, and stake-based anti-Sybil measures, laying the foundation for scalable partner ecosystems. Using Markdown for documentation, Ivo collaborated with external partners to align technical goals, demonstrating depth in protocol design and clear, maintainable technical writing.
