What's Changed

  • feat: paidPredicateGate (#409): a combined gate that resolves identity verification (predicate) and x402 payment in a single 402 round trip. Tools using it need only 2 requests (a 402 advertising the real payment amount, then a 200) instead of 3. The caller's X-Payment signature proves identity, via the recovered from address, and authorizes the transfer in one step. The onchain predicate is checked before the facilitator settles payment, so denied access returns a 403 and moves no funds. New exports: paidPredicateGate and PaidPredicateGateConfig.
  • docs: predicate gate docs updated for the unified 402 + X-Payment flow (#408).
  • fix: the token-nft-overlap-tool example passes operatorAddress in its Vercel entry (#407).
