Getting Started

Getting started to add ERC-4337 smart wallet support to your application easily.

Once set, your application will:

• Let users connect to their smart wallet using any personal wallet, including email and local wallets for easy onboarding.
• Automatically deploy individual account contracts for your users when they do their first onchain transaction.
• Handle all transaction gas costs via the thirdweb paymaster.

Deployable via the explore page or build your own ERC 4337 compatible factory contract using the Solidity SDK.

Choose the right smart wallet setup for your app. thirdweb offers different kinds of smart wallets:

Read about the differences between the smart wallet types here.

You will require an API key to use thirdweb's infrastructure services such as the bundler and paymaster.

Obtain an API key from the thirdweb dashboard Settings page.

The API key lets you access thirdweb's bundler and paymaster infrastructure, which is required for the smart wallet to operate and optionally enable gasless transactions.

The API key will need to have the following settings:

• smart wallet as an enabled service
• The contracts that the smart wallet will interact with must be added to the "Destination Contracts" list. Learn more here

Learn more about creating an API key and restricting which contracts the smart wallet can interact with here.

Use the following code to integrate smart wallets into your apps. This will:

• Connect your users to their smart wallet based on their personal wallet (can be any wallet, including email or local wallets).
• Automatically deploy the individual account contracts for your users when they do their first onchain transaction.
• Handle all transaction gas costs via the thirdweb paymaster.
• Select your deployed account factory and client ID to get use the thirdweb infrastructure.

import {
  ThirdwebProvider,
  ConnectWallet,
  smartWallet,
  embeddedWallet,
} from "@thirdweb-dev/react";
 
export default function App() {
  return (
    <ThirdwebProvider
      clientId="YOUR_CLIENT_ID"
      activeChain="sepolia"
      supportedWallets={[
        smartWallet(
          embeddedWallet(), // any personal wallet
          {
            factoryAddress: "0x...", // your deployed factory address
            gasless: true, // enable or disable gasless transactions
          },
        ),
      ]}
    >
      <ConnectWallet />
    </ThirdwebProvider>
  );
}

Clone these templates to create Smart Wallets and connect to them quickly.

Once setup, you can use the thirdweb TypeScript, React, React Native and Unity SDKs to deploy contracts, perform transactions, and manipulate wallets like any other wallet.

import {
  useAddress,
  useContract,
  useOwnedNFTs,
  Web3Button,
} from "@thirdweb-dev/react";
 
// The ThirdwebProvider setup above already handles connection to the smart wallet
// Within the provider, you can use the react SDK hooks to interact with the blockchain
export default function MyComponent() {
  // Get the connected smart wallet address
  const smartWalletAddress = useAddress();
  // Fetch owned NFTs
  const { contract } = useContract("0x...");
  const { data, isLoading } = useOwnedNFTs(
    contract,
    smartWalletAddress,
  );
  // Mint a new NFT
  return (
    <Web3Button
      contractAddress={"0x..."}
      action={(contract) =>
        contract.erc721.mint({
          name: "My NFT",
          description: "My NFT description",
          image: "https://example.com/image.png",
        })
      }
    >
      Mint NFT
    </Web3Button>
  );
}
