@aa-sdk/ethers

This package contains EthersProviderAdapter and AccountSigner, respective extensions of the JsonRpcProvider and Signer classes defined in ethers.js external library.

If you currently rely ethers.js for web3 development, you can use these ethers.js-compatible JsonRpcProvider and Signer to integrate Account Abstraction into your dApp. You may also find the util methods helpful.

This repo is community maintained and we welcome contributions!

Getting started

If you are already using the @aa-sdk/core package, you can simply install this package and start using the EthersProviderAdapter and AccountSigner. If you are not using @aa-sdk/core, you can install it and follow the instructions in the "Getting started" docs to get started.

yarn add @aa-sdk/ethers

npm i -s @aa-sdk/ethers

pnpm i @aa-sdk/ethers

Usage

You can create a provider and connect it to a signer account like so:

import {
  LightSmartContractAccount,
  getDefaultLightAccountFactoryAddress,
} from "@alchemy/aa-accounts";
import { EthersProviderAdapter } from "@aa-sdk/ethers";
import { LocalAccountSigner, SmartAccountSigner } from "@aa-sdk/core";
import { Alchemy, Network } from "alchemy-sdk";
import { polygonMumbai } from "@aa-sdk/core";

const chain = polygonMumbai;

// 1. Create a provider using EthersProviderAdapter
const alchemy = new Alchemy({
  apiKey: process.env.API_KEY!,
  network: Network.MATIC_MUMBAI,
});
const ethersProvider = await alchemy.config.getProvider();

const provider = EthersProviderAdapter.fromEthersProvider(ethersProvider);

const signer: SmartAccountSigner = LocalAccountSigner.mnemonicToAccountSigner(
  process.env.YOUR_OWNER_MNEMONIC!
);

// 2. Connect the provider to the smart account signer
export const signer = provider.connectToAccount(
  (rpcClient) =>
    new LightSmartContractAccount({
      chain,
      factoryAddress: getDefaultLightAccountFactoryAddress(chain),
      rpcClient,
      signer,
    })
);
