Jiayao Qi developed and integrated the AltLayer Ecosystem Partnership within the coinbase/x402 repository, focusing on infrastructure development and tooling integration. By onboarding AltLayer as an infrastructure and tooling partner, Jiayao enabled access to the AltLayer x402 suite, which includes gateway, facilitator, and decentralized agent hosting autonomes. The work involved close collaboration on infra and API alignment, ensuring seamless integration of partner services into the existing x402 ecosystem. Using JSON for configuration and data exchange, Jiayao established a foundation for future partner integrations, expanding deployment options and enhancing the overall tooling infrastructure for x402 users during the project period.
