MetaMask
Browser extension and mobile app to interact with the blockchain.
Beginner-friendly explanation
MetaMask is a digital wallet installed as a browser extension or mobile app. It lets you store cryptocurrencies and easily interact with Web3 websites (like buying an NFT or using a DeFi app).
Example:
You use MetaMask to connect to an NFT marketplace and purchase a digital artwork.
Intermediate-level insight
MetaMask is a non-custodial wallet based on Ethereum but compatible with multiple blockchains (Polygon, Binance Smart Chain, etc.). It handles transaction signing and lets you interact with smart contracts directly from your browser.
Example:
You join a DeFi project by signing a transaction via MetaMask without ever revealing your private key.
Advanced perspective
MetaMask offers advanced features like multi-account management, RPC customization for specific blockchain connections, and direct DeFi integrations (built-in swap). Its security relies on the execution environment's safety (browser or mobile).
Example:
A developer configures MetaMask with a custom RPC to test a smart contract on a private network.
