deposit

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

Called by the buyer to lock the agreed amount of tokens into the escrow contract.

The SDK does everything for you:

• Checks your balance
• Resets allowance if needed (USDT pattern)
• Approves the exact amount
• Calls deposit(escrowId) on the contract

Parameters

• walletClient: WalletClient – Buyer’s connected wallet
• escrowId: bigint – The escrow ID

Returns

Promise<string> – Transaction hash

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

const { sdk, walletClient } = await connectAndInitSDK(); // walletClient = buyer's wallet

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

  console.log("Deposit successful!");
  console.log("Transaction:", txHash);
  console.log("Funds are now locked in escrow #42");

  // Escrow state → AWAITING_DELIVERY
  // Seller must now deliver the product/service

} catch (error: any) {
  if (error.code === "INSUFFICIENT_BALANCE") {
    alert("Not enough USDT in your wallet");
  } else if (error.code === "ALLOWANCE_FAILED") {
    alert("Approval failed — try again");
  } else {
    console.error("Deposit failed:", error.shortMessage || error.message);
  }
