PaySats

Stacks Integration Foundation + USDCx/sBTC Swap Flow Implement the initial Stacks integration foundation for the PaySats pilot; add support for the user account, wallet/signing, and balance flow needed for Stacks-based USDCx and sBTC actions; implement a USDCx to sBTC swap flow using Bitflow; require user approval before any transaction is submitted; provide a public repo or public implementation reference, setup documentation, and demo video.

Core Stacks Loop Live — DCA into sBTC + Borrow on Zest Implement the PaySats Stacks DCA flow for recurring USDCx to sBTC purchases; add DCA status, history, and cancellation functionality; implement the Zest integration for borrowing USDCx against sBTC; show the full save-and-borrow user flow inside PaySats; provide transaction records, demo video, and documentation for the DCA and Zest borrow flows.

MCP Agent Layer + Mainnet Pilot Adoption Extend the PaySats MCP server to support Stacks-based account, DCA, sBTC, and borrowing actions; enable an AI agent to initiate supported PaySats actions with human approval before execution; launch the Stacks pilot on mainnet; publish MCP documentation, supported tool definitions, release notes, and a recorded agent demo; provide a final grant update with links to product, repo or implementation reference, documentation, demo, transaction evidence, adoption metrics, and known limitations. Usage requirements: at least 10 pilot users onboarded; at least 5 pilot users complete a USDCx to sBTC save action through PaySats; at least 3 recurring DCA plans created; at least 2 DCA plans complete more than one scheduled purchase; at least 1 Zest borrow flow completed or an approved mainnet-ready verification path if Zest constraints prevent completion; at least 10 MCP-initiated actions completed with human approval; at least 3 MCP-initiated actions performed by users or agents not operated by PaySats.
