acceptEscrow - Palindrome Crypto Pay SDK Documentation

async acceptEscrow(walletClient: WalletClient, escrowId: bigint): Promise<{ txHash: Hex; signatureValid: boolean }>

Called by the seller when the buyer created the escrow via createEscrowAndDeposit(). The seller must accept to provide their wallet authorization signature, which is required for the 2-of-3 multisig withdrawal mechanism.

Without accepting, the seller cannot receive funds even if the buyer confirms delivery.

Parameters

walletClient: WalletClient – Seller's connected wallet
escrowId: bigint – The escrow ID to accept

Returns

Promise<{ txHash: Hex; signatureValid: boolean }> – Transaction hash and signature verification result

import { createPalindromeSDK } from '@/lib/createSDK';

const { sdk, walletClient } = await connectAndInitSDK(); // walletClient = seller

try {
  const { txHash, signatureValid } = await sdk.acceptEscrow(walletClient, 42n);

  console.log("Escrow accepted!");
  console.log("You can now receive funds when buyer confirms delivery");
  console.log("Transaction:", txHash);
  console.log("Signature valid:", signatureValid);

  // Your wallet signature is now registered
  // When buyer confirms, funds will be released to you

  if (error.code === "NOT_SELLER") {
    alert("Only the seller can accept this escrow");
  } else if (error.code === "INVALID_STATE") {
    alert("Escrow is not in AWAITING_DELIVERY state");
  } else if (error.code === "ALREADY_ACCEPTED") {

  } else {
    console.error("Accept failed:", error.shortMessage || error.message);
  }
}
