Send a simple transaction

Overview

This tutorial demonstrates how to send a simple transaction using ethers.js/web3.js and the AbstraXn Smart Account with the @abstraxn/account SDK.

Prerequisites

• Node.js installed on your machine
• A Bundler url
• An rpc url
• An address to send the transaction to (replace 0xaddress)

Step 1: Generate the config and Create AbstraXn Smart Account

web3.js

import { web3 } from "web3";
import { createSmartAccountClient } from "@abstraxn/account";

// Your configuration with private key and AbstraXn API key
const config = {
  privateKey: "your-private-key",
  bundlerUrl: "", 
};

const web3 = new Web3(config.rpcUrl);

// Generate EOA from private key using ethers.js
const account = web3.eth.accounts.privateKeyToAccount(config.privateKey);

const signer = createWalletClient({
  account,
  chain: polygonAmoy,
  transport: http(),
});

// Create AbstraXn Smart Account instance
const abstraxnSmartAccount = await AbstraxnSmartAccount.create({
    chainId: ChainId.POLYGON_AMOY, // you can use multiple chains available in chainId object
    activeValidationModule: ownerShipModule,
    defaultValidationModule: ownerShipModule,
    bundler: bundler, // instance of bundler
});

const saAddress = await abstraxnSmartAccount.getAccountAddress();
console.log("SA Address", saAddress);

ethers.js

import { ethers } from "ethers";
import { createSmartAccountClient } from "@abstraxn/account";

// Your configuration with private key and AbstraXn API key
const config = {
  privateKey: "your-private-key",
  bundlerUrl: "", 
  rpcUrl: "rpc-url",
};

// Generate EOA from private key using ethers.js
let provider = new ethers.JsonRpcProvider(config.rpcUrl)();
let signer = new ethers.Wallet(config.privateKey, provider);

// Create AbstraXn Smart Account instance
const abstraxnSmartAccount = await AbstraxnSmartAccount.create({
    chainId: ChainId.POLYGON_AMOY, // you can use multiple chains available in chainId object
    activeValidationModule: ownerShipModule,
    defaultValidationModule: ownerShipModule,
    bundler: bundler, // instance of bundler
});

const saAddress = await abstraxnSmartAccount.getAccountAddress();
console.log("SA Address", saAddress);

Get your signer from either ethers.js or web3.js and create an Abstraxn account instance.

Step 2: Generate Transaction Data

const toAddress = "0xaddress"; // Replace with the recipient's address
const transactionData = "0x123"; // Replace with the actual transaction data

// Build the transaction
const tx = {
  to: toAddress,
  data: transactionData,
};

Specify the recipient's address and transaction data to build the simple transaction.

Step 3: Send the Transaction and wait for the Transaction Hash

// Send the transaction and get the transaction hash
const userOpResponse = await smartWallet.sendTransaction(tx);
const { transactionHash } = await userOpResponse.waitForTxHash();
console.log("Transaction Hash", transactionHash);

const userOpReceipt  = await userOpResponse.wait();
if(userOpReceipt.success == 'true') { 
  console.log("UserOp receipt", userOpReceipt)
  console.log("Transaction receipt", userOpReceipt.receipt)
}

Send the transaction using the AbstraXn Smart Account and get the transaction hash. The transaction will be built into a User Operation and then sent to the Bundler.

That's it! You've successfully sent a simple transaction using ethers.js/web3.js and the AbstraXn Smart Account. Feel free to customize this example based on your specific use case.
