Welcome

Welcome to the MetaMask Wallet API documentation!

The MetaMask Wallet API enables you to:

• Connect web dApps to MetaMask browser extension
• Interact with users' Ethereum accounts
• Send transactions and sign messages
• Listen to account and network changes

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.

Looking for MetaMask SDK?
