Integrate your dapp with the MetaMask wallet
Integrate your dapp with MetaMask using MetaMask SDK and the Wallet API. Use MetaMask SDK to create a seamless connection between your dapp and MetaMask across desktop and mobile platforms. Use the Wallet API to interact with users' EVM accounts in MetaMask.
Get started by connecting to MetaMask.
Why use MetaMask SDK?
MetaMask SDK enables a reliable, secure, and seamless connection between your dapp and the MetaMask browser extension or MetaMask Mobile, providing cross-platform compatibility with a consistent user experience. Key benefits include:
- Multi-platform support – Connect from web, desktop, mobile, and gaming platforms.
- Seamless connections – Minimize reconnections and improve user experience, especially on mobile.
- Mobile-first optimization – Enable faster wallet interactions with instant deeplinks and advanced features.
- Enhanced functionality – Use RPC request batching, EIP-6963 for wallet discovery, and wallet security enhancements.
- Third-party library integration - Use libraries like Wagmi or Web3-Onboard that integrate SDK support.
The Wallet API allows you to interact with users' EVM accounts using standardized JSON-RPC calls. While you can connect to the MetaMask extension directly using just the Wallet API, we recommend using the SDK or third-party libraries in conjunction with the Wallet API, to take advantage of the SDK's benefits.
