Metamask is a cryptocurrency wallet used to interact with the Ethereum blockchain. It allows users to access their Ethereum wallet through a browser extension or mobile app, which can then be used to interact with decentralized applications.

​
Connecting via Metamask

If you want the user to be able to sign in via Metamask, we can simply import the MetaMaskWalletProvider object like so: 
import { MetaMaskWalletProvider } from '@etherspot/prime-sdk';
Then call connect on it which will prompt the user to connect their Metamask. Finally, we pass this provider into the Prime SDK to instantiate it. 
const metamaskProvider = await MetaMaskWalletProvider.connect();
const primeSdk = new PrimeSdk(metamaskProviderTemp, { chainId: 11155111, bundlerProvider: new EtherspotBundler(11155111, bundlerApiKey) });

​
Transaction Kit

For transaction kit we can follow the same process above, then pass the provider straight into the Transaction kit tags like this: 
const metamaskProvider = await MetaMaskWalletProvider.connect();

<EtherspotTransactionKit provider={metamaskProvider}>
</EtherspotTransactionKit>
