Create a client and send a user operation

The code snippets below demonstrate how to use LightAccount and MultiOwnerLightAccount with Account Kit. They create the account and send a UserOperation from it.

import { createLightAccountAlchemyClient } from "@alchemy/aa-alchemy";
import { LocalAccountSigner, sepolia } from "@alchemy/aa-core";
import type { Hex } from "viem";
const chain = sepolia;
// The private key of your EOA that will be the signer of Light Account
const PRIVATE_KEY: Hex = "0xYourEOAPrivateKey";
const signer = LocalAccountSigner.privateKeyToAccountSigner(PRIVATE_KEY);
// Create a provider to send user operations from your smart account
const provider = await createLightAccountAlchemyClient({
  // get your Alchemy API key at
  apiKey: "ALCHEMY_API_KEY",
  version: "v2.0.0", // Required if not v1.1.0
// Fund your account address with ETH to send for the user operations
// (e.g. Get Sepolia ETH at
console.log(provider.getAddress()); // Log the smart account address
// Send a user operation from your smart account
const { hash: uoHash } = await provider.sendUserOperation({
  uo: {
    target: "0xTargetAddress", // The desired target contract address
    data: "0xCallData", // The desired call data
    value: 0n, // (Optional) value to send the target contract address
console.log(uoHash); // Log the user operation hash
// Wait for the user operation to be mined
const txHash = await provider.waitForUserOperationTransaction({ hash: uoHash });
console.log(txHash); // Log the transaction hash
