requestCancel

async requestCancel(walletClient: WalletClient, escrowId: bigint): Promise<string>

Called by buyer or seller to signal they want to cancel the deal.

• If both parties request cancel → escrow becomes CANCELED automatically after timeout
• If only one requests → the other can still proceed (e.g. buyer can deposit, seller can deliver)

This is the first step in mutual cancellation.

Parameters

• walletClient: WalletClient – Your wallet (buyer or seller)
• escrowId: bigint

Returns

Promise<string> – Transaction hash

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

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

try {
  const txHash = await sdk.requestCancel(walletClient, 42n);

  console.log("Cancellation request sent!");
  console.log("Tx:", txHash);

  // Now waiting for the other party...
  if (/* other party also requested */) {
    console.log("Both requested → will auto-cancel soon");
  } else {
    console.log("Waiting for counterparty to agree");
  }

} catch (error: any) {
  if (error.code === "INVALID_STATE") {
    alert("Cannot cancel in current state (e.g. already disputed or completed)");
  } else {
    console.error("Request cancel failed:", error.shortMessage || error.message);
  }
}
