Seamlessly connect to MetaMask using the SDK
MetaMask SDK enables a fast, reliable, and seamless connection from your dapp to the MetaMask extension and MetaMask mobile app. With the SDK, you can easily onboard users and interact with their accounts on desktop or mobile, across all EVM networks.
Why use the SDK?
MetaMask SDK gives your dapp a powerful upgrade:
- Cross-platform, cross-browser support - One integration covers both desktop and mobile, all major browsers, and the MetaMask mobile app—streamlining your user onboarding and eliminating edge cases.
- Mobile connection that just works - Say goodbye to clunky "open in in-app browser" flows. The SDK enables a native connection from any mobile browser (Safari, Chrome, etc.) directly to the MetaMask mobile app, using secure deeplinking and session management.
- Production-ready, battle-tested - MetaMask SDK is used in high-volume dapps across DeFi, NFTs, gaming, and more—ensuring stability, speed, and a smooth developer experience.
- Multichain-ready by design - Today, the SDK supports all EVM networks. Coming soon: Seamless connection to non-EVM chains like Solana and Bitcoin. Futureproof your dapp with a single integration.
Supported platforms and libraries
MetaMask SDK is available in a variety of ways to make integration as easy as possible. You can access it directly via npm, through popular developer libraries like Wagmi, or as part of popular convenience libraries.
