metamaskWallet

Defined in thirdweb/src/wallets/injected/wallets/metamask.ts#L59

metamaskWallet allows you to connect to the MetaMask Wallet extension.

If you want to connect to MetaMask wallet mobile app, use walletConnect instead.

Example

import {
  metamaskWallet,
  injectedMetamaskProvider,
} from "thirdweb/wallets";
 
async function connectToMetamask() {
  const isInstalled = !!injectedMetamaskProvider();
 
  // if metamask extension is installed, connect to MetaMask extension
  if (isInstalled) {
    // create an instance
    const wallet = metamaskWallet();
    try {
      const account = await wallet.connect(); // connect to it
      console.log("connected to", account);
    } catch (e) {
      console.error("error connecting to metamask", e);
    }
  }
 
  // else prompt user to connect to MetaMask wallet app by scanning a QR code
  else {
    // refer to `walletConnect` documentation
  }
}

If you want the wallet to be connected to a specific blockchain, you can pass a Chain object to the connect method. This will trigger a chain switch if the wallet provider is not already connected to the specified chain.

You can create a Chain object using the defineChain function. At minimum, you need to pass the id of the blockchain.

import { defineChain } from "thirdweb";
const mumbai = defineChain({
  id: 80001,
});
 
const address = await wallet.connect({ chain: mumbai });

Returns

The InjectedWallet instance
