Seamlessly connect to the MetaMask wallet
MetaMask Connect enables a fast, reliable connection from your dapp to the MetaMask browser extension and the MetaMask mobile app. With a single integration, you can onboard users and interact with their accounts across desktop browsers, mobile browsers, and native apps. It offers multiple integration options, from single-ecosystem clients for EVM or Solana to a multichain client that connects to multiple chains in a single session.
MetaMask Connect replaces the legacy MetaMask SDK with a complete rewrite built on the CAIP-25 Multichain API and a more secure and robust relay server infrastructure for improved reliability. The MetaMask Connect SDK detects the user’s environment and selects the best connection method, whether it communicates directly with the MetaMask browser extension, prompts the user to scan a QR code, or deep links to the MetaMask mobile app.
Why use MetaMask Connect?
If the MetaMask browser extension is installed, standards such as EIP-6963 and EIP-1193 support wallet discovery. When the extension isn't available (for example, on mobile, in a different browser, or on a new device), users need another way to connect. MetaMask Connect fills that gap and provides the following benefits:
- Cross-platform connections: Reach users on any device. When the MetaMask browser extension isn’t available, MetaMask Connect connects users through the MetaMask mobile app with no additional setup.
- Multichain sessions : Request access to EVM, Solana, and future ecosystems in a single connection instead of connecting per chain.
- Persistent sessions: Keep sessions across page reloads and new tabs so users don’t need to reconnect.
- Consistent API: Use the same interface whether users connect through the extension or MetaMask Mobile.
