SmartWallet
Let your users connect to a Smart Wallet .
A Smart Wallet is a wallet that is controlled by a smart contract following the ERC-4337 specification .
For a complete overview of Smart Wallets, visit the Smart Wallet SDK documentation
References
To connect to a smart wallet, a personal wallet (acting as the key to the smart wallet) must first be connected.
import { LocalWallet, SmartWallet } from "@thirdweb-dev/wallets";import { Goerli } from "@thirdweb-dev/chains"; // First, connect the personal wallet, which can be any wallet (metamask, walletconnect, etc.)// Here we're just generating a new local wallet which can be saved laterconst personalWallet = new LocalWallet();await personalWallet.generate(); // Setup the Smart Wallet configurationconst config: SmartWalletConfig = { chain: Goerli, // the chain where your smart wallet will be or is deployed factoryAddress: "{{factory_address}}", // your own deployed account factory address clientId: "YOUR_CLIENT_ID", // Use client id if using on the client side, get it from dashboard settings secretKey: "YOUR_SECRET_KEY", // Use secret key if using on the server, get it from dashboard settings gasless: true, // enable or disable gasless transactions}; // Then, connect the Smart walletconst wallet = new SmartWallet(config);await wallet.connect({ personalWallet,}); // You can then use this wallet to perform transactions via the SDKconst sdk = await ThirdwebSDK.fromWallet(wallet, Goerli);
