MetaMask overview
MetaMask, built by ConsenSys and first released in 2016, is the most widely used self-custody crypto wallet for Ethereum and EVM-compatible chains, with tens of millions of monthly active users. For this MetaMask review I installed both the browser extension and the mobile app, funded a fresh wallet, connected to several dApps, and ran swaps, bridges and a hardware-wallet pairing to see how it performs in 2026.
It ships as a Chrome, Firefox, Brave and Edge extension plus iOS and Android apps, with an in-app browser on mobile so you can reach dApps without a desktop.
Fees & pricing
The app itself is free to download and holds no custody of your funds. MetaMask fees show up in two places: unavoidable network gas paid to the blockchain, and optional service fees on the tools MetaMask bundles in.
- Network gas: variable, set by the chain, not by MetaMask
- In-app swaps: about 0.875% service fee baked into the quote
- Bridging: a similar built-in fee plus the bridge provider's cut
- Buy/sell on-ramp: third-party provider spreads apply
Routing the same swap directly through a DEX like Uniswap usually costs less, so the convenience fee is the price of staying inside one interface.
Security
Is MetaMask safe? Architecturally, yes: it is non-custodial and open-source, your private keys and Secret Recovery Phrase are encrypted locally and never sent to ConsenSys, and it supports Ledger and Trezor so keys can live on a hardware device. The code has been audited repeatedly.
The bigger risk is you. Because MetaMask is so popular, it is a magnet for phishing sites, fake support staff and malicious token-approval scams. Nobody can reverse a transaction or recover a lost seed phrase, so the burden of caution sits entirely on the user.
Features
Beyond storing assets, MetaMask packs in token swaps, cross-chain bridging, ETH staking, NFT display, a fiat on-ramp, and Snaps, which are plugins that extend the wallet to non-EVM chains like Bitcoin and Solana. The MetaMask Portfolio dashboard tracks balances across networks, and developers lean on it as the default injected provider for testing dApps.
Ease of use
Setup takes a couple of minutes and the interface is cleaner than most wallets, but the learning curve is real for newcomers. Concepts like gas, network switching, slippage and token approvals are not obvious, and adding a custom RPC or spotting a scam approval assumes some knowledge. Experienced users will feel at home; total beginners should move slowly.
Verdict
MetaMask earns its status as the standard EVM wallet through unrivaled dApp compatibility, genuine self-custody and a deep feature set. The above-market in-app swap fees and the constant phishing threat keep it short of a perfect score. For hands-on Ethereum and DeFi users who guard their seed phrase, it is a top choice; cautious beginners may want a simpler, more guided wallet. This is not financial advice.
