System Documentation

What problem does it solve?

This Skill solves the hassle of creating and settling onchain A2A payment links by guiding you through seller creation, buyer payment execution, and payment status polling.

Core Features & Use Cases

  • Seller flow: create payment links for a specific token amount and recipient, returning a paymentId and an optional shareable URL.
  • Buyer flow: pay paymentId (a2a-pay) by signing the seller-provided on-server challenge and submitting the EIP-3009 authorization.
  • Status flow: check and auto-poll terminal outcomes (completed, failed, expired, cancelled) after payment attempts.

Quick Start

Tell the assistant: Create a USDT payment link for 0.01 to my seller wallet, then later pay it using the paymentId you provided.
