Privy is fully compatible with popular web3 libraries for interfacing wallets, including viem, wagmi, ethers, and web3js.
Read below to learn how to best integrate Privy alongside these libraries.

​
Viem

Viem represents connected wallets as either an account object, which can sign with the wallet, or a wallet client object, which can also send transactions from the wallet.

​
Getting an account

To get an account for a user’s connected wallet, import the toViemAccount method and the useWallets hook from the React SDK.
import {toViemAccount, useWallets} from '@privy-io/react-auth';
Then, pass the ConnectedWallet object for your user’s wallet to the method, which will return a LocalAccount instance.
const {wallets} = useWallets();

const wallet = wallets.find((wallet) => (wallet.address === 'your-desired-address'));
const account = await toViemAccount({wallet});
You can then use the account to sign messages, typed data payloads, and transactions.

​
Getting a wallet client

To get a viem wallet client for a user’s connected wallet, first import your desired network from the viem/chains package and import the createWalletClient method and custom transport from viem:
import {createWalletClient, custom} from 'viem';
// Replace `sepolia` with your desired network
import {sepolia} from 'viem/chains';
Then, find your desired wallet from the wallets array and switch its network to the chain you imported, using the wallet’s switchChain method:
const {wallets} = useWallets();
const wallet = wallets[0]; // Replace this with your desired wallet
await wallet.switchChain(sepolia.id);
Lastly, get the wallet’s EIP1193 provider using the wallet’s getEthereumProvider method and pass it to viem’s createWalletClient method like so:
const provider = await wallet.getEthereumProvider();
const walletClient = createWalletClient({
    account: wallet.address as Hex,
    chain: sepolia,
    transport: custom(provider),
});
You can then use the wallet client to get information about the wallet or request signatures and transactions.

​
Wagmi

Privy is fully compatible with wagmi. Please see our wagmi guide for setting up the integration.

​
Ethers

​
Ethers v5

const privyProvider = await wallet.getEthereumProvider();
const provider = new ethers.providers.Web3Provider(privyProvider);

​
Ethers v6

const provider = await wallet.getEthereumProvider();
const ethersProvider = new ethers.BrowserProvider(provider);
const signer = ethersProvider.getSigner();

​
Web3.js

Web3.js represents connected wallets as a Web3 object, which you can use to get information about the current wallet or the request signatures and transactions.To get a Web3js provider for a user’s connected wallet, first find your desired wallet from the wallets array and switch it to your desired network, using the wallet’s switchChain method:
const {wallets} = useWallets();
const wallet = wallets[0]; // Replace this with your desired wallet
await wallet.switchChain(sepolia.id);
Then, get the wallet’s EIP1193 provider using the wallet’s getEthereumProvider method and pass it to Web3js’s Web3 constructor like so:
const provider = await wallet.getEthereumProvider();
const web3 = new Web3(provider);
You can then use the Web3 provider to get information about the wallet or request signatures and transactions.
