Advanced Usage

This section covers advanced customization options for your UserOperations.

Custom Gas Parameters

You can customize gas parameters for your UserOperations:

// Set specific gas values
builder.setCallGasLimit("0x88b8");
builder.setVerificationGasLimit("0x33450");
builder.setPreVerificationGas("0xc350");
builder.setMaxFeePerGas("0x2162553062");
builder.setMaxPriorityFeePerGas("0x40dbcf36");

Custom Nonce Management

If needed, you can manually set the nonce for your UserOperations:

// Get the current nonce
const aaWallet = new ethers.Contract(
  aaWalletAddress,
  ['function getNonce() view returns (uint256)'],
  accountSigner
);
const nonce = await aaWallet.getNonce();
 
// Set a custom nonce
builder.setNonce(nonce.add(1));

Additional Customization

Beyond gas parameters and nonce management, you can also:

Customize the signature mechanism
Implement your own account abstraction logic
