Integrate with the MetaMask wallet

Integrate your dapp with the MetaMask wallet using the MetaMask Ethereum provider API, which enables your dapp to interact with its users' Ethereum accounts. We recommend using MetaMask SDK to easily enable your users to connect to their MetaMask wallet client from any platform.

Get started by setting up your development environment.


What is the MetaMask Ethereum provider API?

The MetaMask Ethereum provider API is a JavaScript API that MetaMask injects into websites visited by MetaMask users. Your dapp can use this API to request users' Ethereum accounts, read data from blockchains the user is connected to, and suggest that the user sign messages and transactions.

What is 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 into your dapp to enable your users to easily connect to a MetaMask wallet client from multiple platforms (web, desktop, and mobile).

For example, for dapps running on a desktop browser, MetaMask SDK checks if the MetaMask extension is installed. If MetaMask isn't installed, the SDK prompts the user to install it or connect to their MetaMask Mobile wallet using a QR code. For dapps running on a mobile browser, MetaMask SDK automatically deeplinks to the user's MetaMask Mobile wallet to make the connection.


If you have questions about integrating your dapp with MetaMask, you can interact with the MetaMask team and community on the MetaMask channels on ConsenSys Discord.
