connectToAccount

connectToAccount is a method on EthersProviderAdapter that you can optionally call to connect the provider to an account and returns a AccountSigner. This enables the returned AccountSigner to leverage the provider when signing messages, UserOperations, and transactions for a smart account using the connected EOA signer account.

Usage

import { createLightAccount } from "@alchemy/aa-accounts";
import {
  LocalAccountSigner,
  SmartAccountSigner,
  polygonMumbai,
} from "@alchemy/aa-core";
import { http } from "viem";
import { provider } from "./ethers-provider.js";
 
const eoaSigner: SmartAccountSigner =
  LocalAccountSigner.mnemonicToAccountSigner(process.env.YOUR_OWNER_MNEMONIC!);
 
const chain = polygonMumbai;
 
// 2. Connect the provider to the smart account signer
export const accountSigner = provider.connectToAccount(
  await createLightAccount({
    chain,
    transport: http("RPC_URL"),
    signer: eoaSigner,
  })
);

Returns

AccountSigner<TAccount extends SmartContractAccount>

A new instance of a connected AccountSignerfor any implementation class of SmartContractAccount

Parameters

account: TAccount extends SmartContractAccount

A function that takes in the provider's rpcClient and returns an AccountSigner
