MetaMask SDK for Dapp Developers

For Dapp Developers: The MetaMask JavaScript SDK can be used with any web application, Electron desktop app or ReactNative project. At its most basic implementation, one must install the @metamask/sdk using npm and instantiate the SDK inside your project. This ensures that when eth_requestAccounts is called, the user can connect to MetaMask Mobile (or Extension within a web browser).

For React developers, in particular, we have several dedicated React packages that include the @metamask/sdk with Context and UI components.

As well we have a minimal examples directory within the JavaScript SDK repo which can get you up to speed with Create React App, Electron, NextJS, NodeJS, Pure Javascript, ReactNative, and VueJS. These are cut-to-the-chase examples for all JavaScript project types.

Why MetaMask SDK?

The MetaMask SDK is a library that provides a reliable, secure, and seamless connection from your dapps and web3 games and mobile apps to MetaMask Mobile.

The MetaMask SDK solves that by being a solution that works on every Javascript frontend/backend platform (Web, React, React Native, NodeJS), as well as mobile (native iOS & Android), Unity (mobile, desktop and WebGL) and we are expanding these supported platforms in the future as well a creating supporting component libraries.
