Magic Link

Our Smart Accounts are signer agnostic, in this how to guide we'll show you how to incorporate Magic Link for creating a login experience that uses google login/email/or connect wallet all using the Magic Link UI. You can also add more features such as Social Login by building on top of these snippets, check out the official Magic Documentation for more information.

Dependencies

You will need the following dependencies to create a Smart Account this way:

yarn add @biconomy/account @biconomy/bundler @biconomy/common @biconomy/core-types @biconomy/modules @biconomy/paymaster magic-sdk ethers@5.7.2

Imports

import { IPaymaster, BiconomyPaymaster } from '@biconomy/paymaster'
import { IBundler, Bundler } from '@biconomy/bundler'
import { BiconomySmartAccountV2, DEFAULT_ENTRYPOINT_ADDRESS } from "@biconomy/account"
import { Wallet, providers, ethers } from 'ethers';
import { ChainId } from "@biconomy/core-types"
import { ECDSAOwnershipValidationModule, DEFAULT_ECDSA_OWNERSHIP_MODULE } from "@biconomy/modules";
import { Magic } from 'magic-sdk';

Magic Link Configuration

Magic will require api keys which you can get from the Magic Dashboard.

import { Magic } from "magic-sdk"

// Initialize the Magic instance
export const magic = new Magic("YOUR_API_KEY", {
  network: {
    rpcUrl: "",
    chainId: 11155111, // or preferred chain
  },
})

Biconomy Configuration Values

Set up instances of Bundler, Paymaster. Alternativedly you can also use the Multi chain Module this way.

const bundler: IBundler = new Bundler({
    // get from biconomy dashboard https://dashboard.biconomy.io/
    bundlerUrl: '',     
    chainId: ChainId.POLYGON_MUMBAI,// or any supported chain of your choice
    entryPointAddress: DEFAULT_ENTRYPOINT_ADDRESS,
  })


const paymaster: IPaymaster = new BiconomyPaymaster({
  // get from biconomy dashboard https://dashboard.biconomy.io/
  paymasterUrl: '' 
})

Create the Biconomy Smart Account

const connect = async () => {
    try {
      await magic.wallet.connectWithUI()
      const web3Provider = new ethers.providers.Web3Provider(
        magic.rpcProvider,
        "any"
      );

      const module = await ECDSAOwnershipValidationModule.create({
      signer: web3Provider.getSigner(),
      moduleAddress: DEFAULT_ECDSA_OWNERSHIP_MODULE
      })

      let biconomySmartAccount = await BiconomySmartAccountV2.create({
        chainId: ChainId.POLYGON_MUMBAI,
        bundler: bundler, 
        paymaster: paymaster,
        entryPointAddress: DEFAULT_ENTRYPOINT_ADDRESS,
        defaultValidationModule: module,
        activeValidationModule: module
      })

      const address = await biconomySmartAccount.getAccountAddress()
    } catch (error) {
      console.error(error);
    }
  };
