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 MetaMask Mobile, 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.
