What it can do
How the score breaks down
Each dimension is explained on the methodology page.
Where it is strong and where it is not
✓ Strengths
- Supported by practically every dapp in existence
- Snaps extend it to Solana, Bitcoin and Cosmos
- Broad hardware wallet support
- Custom networks are trivial to add
✗ Weaknesses
- In-wallet swap fee is roughly nine times a typical DEX fee
- No transaction simulation by default, so drainer attacks land
- Interface assumes you know what a nonce is
Incident history
No security breach or significant incident on record.
MetaMask will never ask for your seed phrase. Any site, popup or support agent asking for it is stealing from you.
Reputation and reviews
A reputation score out of 100, kept separate from the feature score above. It reflects what users actually report over time rather than a star rating scraped on one day.
REPUTATION
74/100
Universally supported and universally complained about. The recurring themes are the expensive in-wallet swap, occasional RPC failures, and an interface that assumes prior knowledge. Nothing structural.
Check current reviews yourself
Star ratings change constantly, so we link to the sources rather than printing a number that is out of date the day after it is written.
If something goes wrong
COMMON FIXES
Transaction stuck pendingYour transaction has sat as Pending for minutes or hours and nothing is moving.Transaction failed but the gas was still takenThe transaction reverted, you got nothing, and the fee left your wallet anyway.Token is not showing in my walletThe block explorer shows the tokens arrived, but the wallet shows nothing.I sent tokens to the wrong networkYou withdrew to your address but picked the wrong chain, and the balance is not where you expected.
RISK WARNING
Crypto assets are highly volatile and largely unregulated. You can lose everything you put in.
Nothing on this page is financial, investment or tax advice, and nothing here is a recommendation
to buy or sell any asset. Do your own research and never commit money you cannot afford to lose.
