Integrate your dapp with the MetaMask wallet

Integrate your dapp with MetaMask to interact with your dapp users' Ethereum accounts. You can enable users to connect to their MetaMask wallets from the following dapp platforms:

• Web dapps on desktop and mobile browsers
• Desktop and mobile dapps
• Games built on platforms such as Unity

Integrate using MetaMask SDK

Set up MetaMask SDK to start integrating your dapp with MetaMask. MetaMask SDK is a library that provides a reliable, secure, and seamless connection from your dapp to the MetaMask browser extension and MetaMask Mobile.

With the SDK installed, your dapp can use the MetaMask Ethereum provider API to request users' Ethereum accounts, read data from blockchains the user is connected to, suggest that the user sign messages and transactions, and more.
