What is MetaMask Extension?

MetaMask Extension is a non-custodial Web3 wallet installed as a browser plugin. Unlike centralized exchanges, MetaMask allows users to control their private keys locally, meaning they are the sole custodians of their crypto assets.

This browser-based wallet acts as a bridge between your browser and Ethereum-based blockchains (and other compatible networks), allowing users to:

• Send and receive cryptocurrency
• Interact with smart contracts
• Trade on decentralized exchanges
• Access NFTs and DeFi protocols

MetaMask’s widespread adoption has made it a gateway to the Web3 ecosystem, with millions of active users worldwide.
