What is MetaMask?
MetaMask is a self-custody software wallet for Ethereum and EVM-compatible networks, available as a browser extension and a mobile app. It holds your keys on your own device and connects you to on-chain apps, swaps and NFT platforms. Maintained by Consensys, it is one of the most widely used entry points to decentralized applications.
Track record and what we measured
By our reckoning MetaMask has been operating for roughly 10 years, one of the longest histories in this category. When our probe checked its public site and backend, the response came back at about 312 ms, which is workable rather than fast. We did not find a public status page during our review, so users have limited real-time visibility when something breaks.
This is a hot wallet, meaning the keys live on an internet-connected device. That convenience is also its main risk surface: malware, malicious approvals and phishing sites are the usual ways funds are lost, not the wallet's longevity.
Who is it for?
- People who spend most of their time in Ethereum and other EVM ecosystems.
- DeFi and NFT users who want the broadest app compatibility.
- Developers who need a wallet that virtually every dapp supports.
Who might look elsewhere?
If your assets sit mostly on Solana, Bitcoin or non-EVM chains, a multi-chain wallet may fit better. Anyone holding significant balances should pair any hot wallet with a hardware device for long-term storage.
The honest caveats
Self-custody means there is no support desk that can reverse a mistake or recover a lost seed phrase. You are responsible for your recovery phrase and for every transaction you approve. Our score reflects strong track record and adequate probe performance, held back by the absence of transparent status reporting.
Everyday use
Beyond storing tokens, MetaMask connects to thousands of applications, offers in-app swaps, and lets you add custom networks by RPC. That flexibility is powerful but cuts both ways: adding an unfamiliar network or token contract can expose you to scams, so it pays to add only sources you trust. The wallet's ubiquity also means most guides, integrations and troubleshooting resources assume you are using it, which lowers the learning curve for people entering EVM ecosystems for the first time. Treat that maturity as a convenience, not a substitute for careful signing habits.
