ABI of Settlement v1.

• pay — move amount of token from the caller to merchant, settling one order. The caller must have approved the contract for amount; a smart account does both in one UserOp.
• orderRef — the order reference for these fields, as the contract computes it.
• settled — true once the order with that reference has been paid.
• Settled — the single fact a payment leaves behind; ref is indexed, so a payment can be found by its reference alone.
• AlreadySettled(ref) / Expired(validUntil) / ZeroAmount() — why pay refused.

Example

import { getSettlementAddress, polygonAmoy, settlementAbi } from "kawasekit";

const paid = await publicClient.readContract({
  address: getSettlementAddress(polygonAmoy.id),
  abi: settlementAbi,
  functionName: "settled",
  args: [ref],
});
