Milestone 2: USDCx Reference Integration, Rolling Top-Up Path, and External Validation

An external builder should be able to test LP incentives, vesting, or recurring billing workflows using the SDK and examples.

  • documented generic adapter boundary for downstream tokens
  • non-prefunded / rolling top-up reference path
  • expanded TypeScript SDK and event/query surfaces
  • integration examples for LP incentives, vesting, and recurring billing
  • onboarding guide for new tokens and host-wallet integrations
