Universal Smart Wallet Addresses

Greg

With the thirdweb SDK, all smart wallets maintain the same address across any EVM chain. Account factories and wallet deployments are managed for you from within the thirdweb SDK unless overridden with your own factory. If you need a different wallet address for any reason, you can provide an optional account salt to the wallet.

Create a smart wallet on your default chain:

import { smartWallet } from "thirdweb/wallets";
 
const mySmartWallet = smartWallet({
  chain: sepolia,
  sponsorGas: true,
});

Send your transaction on any chain:

const sendTx = prepareTransaction({
  to: receiver.address,
  value: 100000n,
  chain: baseSepolia,
  client,
});
 
const sendResult = await sendAndConfirmTransaction({
  account: sender,
  transaction: sendTx,
});

If you need to create a wallet using the same admin account but a different address, use an account salt:

const mySmartWallet = smartWallet({
  chain: sepolia,
  sponsorGas: true,
  overrides: {
    accountSalt: "123",
  },
});
