MetaMask Review 2025
The Complete Guide to the World's Leading Web3 Wallet
What Is MetaMask?
MetaMask is the world's leading non-custodial Web3 wallet, serving over 100 million users globally as their gateway to decentralized finance (DeFi), NFTs, and blockchain applications. Originally launched in 2016 by ConsenSys, MetaMask has evolved from a simple Ethereum wallet into a comprehensive Web3 platform that supports multiple blockchain networks and provides seamless access to the decentralized internet.
As a non-custodial wallet, MetaMask gives users complete control over their private keys and cryptocurrency assets. Unlike centralized exchanges or custodial wallets, MetaMask stores your private keys locally on your device, ensuring that only you have access to your funds. This approach aligns with the core principles of cryptocurrency: self-sovereignty and financial independence.
In 2025, MetaMask continues to lead the Web3 wallet space with enhanced security features, improved user experience, expanded network support, and deeper integration with the growing ecosystem of decentralized applications and services.

Frequently Asked Questions
What is MetaMask and how does it work?
MetaMask is a noncustodial Web3 wallet that allows users to store cryptocurrencies, interact with decentralised applications (dApps), manage NFTs, and access DeFi protocols on Ethereum and other EVM-compatible networks. It works as a browser extension or mobile app that manages your private keys locally on your device.
Is MetaMask safe to use?
MetaMask is generally safe when used properly, but security depends on user practices. Key safety measures include using hardware wallets for large amounts, never sharing your seed phrase, verifying dApp URLs, carefully reviewing transaction details, and keeping the software up to date. The wallet itself is secure, but users must be vigilant against phishing and scams.
Does MetaMask support staking?
Yes, MetaMask supports Ethereum staking through integrations with liquid staking providers like Lido and Rocket Pool. Users can stake ETH directly from their MetaMask wallet and receive staking rewards, provided they understand the associated risks and lock-up periods.
What networks does MetaMask support?
MetaMask supports Ethereum mainnet and all EVM-compatible networks, including Polygon, Arbitrum, Optimism, Binance Smart Chain, Avalanche, Fantom, and many others. Users can easily add new networks through the settings or when prompted by dApps. It does not natively support non-EVM chains, such as Bitcoin or Solana.
How much does MetaMask cost?
MetaMask is free to download and use. However, users pay network transaction fees (also known as gas fees) when sending transactions, and MetaMask charges a small fee (typically 0.875%) on token swaps performed through its built-in swap feature. There are no subscription fees or account maintenance costs.
Can I recover my MetaMask wallet if I lose my device?
Yes, you can recover your MetaMask wallet using your 12-word seed phrase (recovery phrase). This phrase allows you to restore your wallet and access your funds on any device. It's crucial to store this phrase securely offline and never share it with anyone.
How do I add new tokens to MetaMask?
You can add tokens to MetaMask by: 1) Using the "Import tokens" feature and entering the token contract address, 2) Having tokens automatically appear when you receive them, or 3) Adding them through dApp interactions. Popular tokens are often pre-loaded in the token list.
What should I do if my transaction is stuck?
If your transaction is stuck, you can: 1) Wait for network congestion to clear, 2) Speed up the transaction by paying higher gas fees, 3) Cancel the transaction (if possible) and retry with higher gas, or 4) Use the "Replace" feature to override the stuck transaction with a new one.
Can I use MetaMask with hardware wallets?
Yes, MetaMask integrates seamlessly with hardware wallets like Ledger and Trezor. This combination provides the convenience of MetaMask's interface with the enhanced security of hardware wallet key storage. You can connect your hardware wallet through MetaMask's settings.
How do I protect myself from MetaMask scams?
