Troubleshooting

// Verify your calldata before sending
import { encodeFunctionData } from "viem";

const callData = encodeFunctionData({
  abi: contractAbi,
  functionName: "transfer",
  args: [recipientAddress, amount],
});

// Test with simulation first
const estimate = await smartWalletClient.estimate({
  payment: sponsored(sponsorApiKey),
  calls: [{ to: contractAddress, data: callData, value: 0n }],
});

// Verify Gas Tank balance before sending
// Visit: https://app.gelato.cloud/ > Paymaster & Bundler > Gas Tank

// For native payments - ensure user has ETH
const balance = await publicClient.getBalance({ address: accountAddress });
if (balance < estimatedGas) {
  console.error("Insufficient native token balance");
}

// For ERC-20 payments - ensure user has approved tokens
const tokenBalance = await publicClient.readContract({
  address: tokenAddress,
  abi: erc20Abi,
  functionName: "balanceOf",
  args: [accountAddress],
});

// Get the counterfactual address before deployment
const accountAddress = account.address;
console.log("Account address:", accountAddress);

// First transaction will deploy the account automatically
// Ensure you have funds for deployment gas

// Ensure you're using the correct signer
const owner = privateKeyToAccount(process.env.PRIVATE_KEY);
console.log("Signer address:", owner.address);

// Verify chain configuration
console.log("Chain ID:", client.chain.id);

// Add timeout to your wait call
const txHash = await Promise.race([
  response.wait(),
  new Promise((_, reject) =>
    setTimeout(() => reject(new Error("Transaction timeout")), 120000)
  ),
]);

// Or check status manually
const receipt = await bundler.getUserOperationReceipt({
  hash: userOpHash,
});

// Log all transaction details
console.log("Account address:", account.address);
console.log("Chain:", client.chain.name);
console.log("Calls:", JSON.stringify(calls, null, 2));

// Always estimate before executing
const estimate = await smartWalletClient.estimate({
  payment: sponsored(sponsorApiKey),
  calls: [...],
});

console.log(`Estimated gas: ${estimate.fee.gas}`);
console.log(`Estimated fee: ${formatEther(estimate.fee.amount)} ETH`);
