Use MetaMask SDK
MetaMask SDK is a library that provides a reliable, secure, and seamless connection from your dapp to the MetaMask browser extension and MetaMask Mobile. You can install the SDK in existing dapps, and call any Wallet API methods from your dapp.
Benefits of MetaMask SDK
MetaMask SDK enables your dapp to provide a seamless user experience for MetaMask users, from multiple dapp platforms, without relying on third-party libraries. By integrating your dapp using the SDK, millions of MetaMask Mobile users can connect to their preferred MetaMask client. The SDK uses the MetaMask Ethereum provider, so existing dapps work out of the box with the SDK.
The following table outlines some of the features available when you integrate your dapp with MetaMask using the SDK. Most of these features are not available if you only integrate your dapp directly using the Wallet API.

| Connect from a web dapp to the MetaMask extension | ✅ | ✅ |
