Overview
MetaMask is the standard wallet for Ethereum and EVM DeFi — a free browser extension and mobile app that connects to a huge range of decentralised apps.
If you're using Ethereum, Layer 2s, or most DeFi and NFT platforms, MetaMask is the wallet they expect. It's powerful and ubiquitous, but it's a hot (online) wallet, and its popularity makes its users a prime target for phishing — so pairing it with a hardware wallet for large balances is strongly advised.
Key features
- The de-facto standard for Ethereum and EVM-chain DeFi
- Browser extension plus mobile app with in-app dApp browser
- Built-in swaps, staking and network switching
- Connects to a hardware wallet for added security
Specs & compatibility
MetaMask is free to download and use; you only pay network gas fees and a small service fee on in-app swaps. It supports Ethereum and any EVM-compatible chain you add. For serious sums, connect a Ledger or Trezor so the keys stay offline.
Security & trust
As a hot wallet, MetaMask's keys live on your device, so device security and phishing awareness are critical. The single biggest risk is scams: fake sites, malicious token approvals, and anyone asking for your 12-word phrase (never share it). Connecting a hardware wallet moves the keys offline and is the recommended setup for larger balances.
