Summary

  • deprecate Handler.feePayer and move shared sponsorship behavior into a reusable internal module
  • make Handler.relay backwards-compatible with the fee-payer surface, including raw transaction sponsorship and legacy sponsor response fields
  • only attempt sponsorship when the incoming request explicitly sets feePayer: true and relay has fee-payer config
  • migrate examples, playgrounds, and provider coverage to use Handler.relay({ feePayer: ... })
  • add focused relay fee-payer compatibility regression tests

Testing

  • pnpm vp test src/server/internal/handlers/relay.feePayer-compat.test.ts src/server/internal/handlers/feePayer.test.ts
  • pnpm vp test src/core/Provider.test.ts -t "feePayer"
