Integration

To use the full potential of the Biconomy Smart Account you will need a bundler url and a paymaster api key. Below is a basic installation and integration for smart accounts in your code.

Installation

First, install the required packages for initializing the Smart Account.

npm

npm install @biconomy/account @biconomy/bundler @biconomy/paymaster @biconomy/common @biconomy/core-types @biconomy/modules

yarn

yarn add @biconomy/account @biconomy/bundler @biconomy/paymaster @biconomy/common @biconomy/core-types @biconomy/modules

pnpm

pnpm add @biconomy/account @biconomy/bundler @biconomy/paymaster @biconomy/common @biconomy/core-types @biconomy/modules

Integration

Now you can simply create smart accounts like this.

  import { ethers } from "ethers";
  import { BiconomySmartAccountV2} from "@biconomy/account";

  let provider = new ethers.providers.JsonRpcProvider("rpcUrl");
  let signer = new ethers.Wallet("private key", provider);

  const biconomySmartAccountConfig = {
    signer: signer,
    chainId: 80002
    biconomyPaymasterApiKey: "https://legacy-docs.biconomy.io/dashboard/paymaster",
    bundlerUrl: ""
  };

  const biconomySmartAccount = await BiconomySmartAccountV2.create(
    biconomySmartAccountConfig
  );

This smart account uses the following default values:

• ECDSA Validation Module
• default entry point address for the chainId
• paymaster instance is created by the SDK
