Reviewers largely see MetaMask as the default Web3 wallet: widely compatible, easy to connect to DApps, mainnets, testnets, and custom networks, with useful extras like swaps, staking, bridging, portfolio views, seed phrase backup, and hardware wallet support. They generally trust its security and say it keeps improving. The main complaints are usability and performance: newcomers can find the interface confusing, some users report lag in basic actions, and NFT display in the extension can be unreliable. One review also describes a withdrawal issue, but overall sentiment is positive.
