Integrate your dapp with MetaMask using the Wallet API
For cross-platform development, mobile integration, or advanced features like QR codes and deeplinking, see the MetaMask SDK documentation.
The Wallet API is MetaMask's core interface for web dapps to interact with the MetaMask browser extension. With the Wallet API, you can:
- Interact with users' EVM and non-EVM accounts.
- Send transactions and sign messages.
- Listen to account and network changes.
The Wallet API uses standardized JSON-RPC calls to interact with users' EVM accounts, and implements standard interfaces like EIP-1193 for Ethereum provider methods and EIP-6963 for wallet detection.
MetaMask also supports non-EVM networks, including native support for Solana.

Wallet API vs. SDK
The Wallet API is designed for web dapps that connect to the MetaMask browser extension. If you're building a desktop web-only dapp, the Wallet API provides everything you need.
MetaMask SDK builds on top of the Wallet API, adding cross-platform support and features like mobile deeplinking and QR code connections. We recommend the SDK if you want to build a cross-platform onchain dapp.
Directly using the Wallet API also enables your dapp to work in the in-app browser of the MetaMask mobile app. However, the SDK offers a more consistent mobile connection.
