1. Installation 🔨

First! Lets setup a Typescript Project in your environment.

Copy paste the below command in your preferred directory.

mkdir axirwallet && cd axirwallet && npm init -y && npm i --save-dev @types/node tslib

Now its time to add our SDK! and viem 🐞

npm i axr-erc4337-sdk && npm i viem

2. Create a Smart Wallet 🔨

Please add a .env file in your project with this format.

PRIVATE_KEY = // your EOA private Key
RPC_URL = // your RPC URL for base sepolia network
BUNDLER_URL = // your pimlico Bundler URL

import { AxirCore } from 'axr-erc4337-sdk';

const axirWallet = new AxirCore(PRIVATE_KEY, RPC_URL, BUNDLER_URL, BigInt(0) /* salt index*/);

The PRIVATE_KEY will be added corresponding to a EOA Signer that will be added as a owner of the Smart Account. You can get get private keys of the EOA Signer from Wallets like Metamask, Coinbase, TrustWallet etc.

We highly suggest you use a dedicate RPC Service for your transactions. You can get RPCs from Infura, QuickNode, etc.
