Usage

Client (create payment)

import { createPayment } from "@erudite-intelligence/x402-zec";

const paymentHeader = await createPayment({
  senderAddress: "t1...",
  senderPrivateKeyWIF: "...",
  recipientAddress: "t1...",
  amount: "0.1",
});
// Set as X-PAYMENT header

import { verifyAndSettle } from "@erudite-intelligence/x402-zec";

Architecture

• Fail-closed: If balance check or broadcast fails, payment is rejected
• Replay protection: In-memory Map with 1hr TTL (use Redis/DB for multi-instance)
• CAIP-2: bip122:00040fe8ec8471911baa1db1266ea15d
• Transparent only: Shielded (z-addr) transactions not supported
