MetaMask is a crypto wallet and gateway to the world of decentralized applications (dApps). It allows you to store cryptocurrency, NFTs, and interact with blockchain applications directly from your browser or mobile phone.
MetaMask uses modern encryption methods. Your private keys are stored locally on your device and are never transmitted to servers. The main thing is to keep the secret phrase (seed phrase) in a safe place and never show it to anyone.
To recover a wallet, you need the 12-word secret phrase you received when creating it. Enter it in the app or extension by selecting the "Import Wallet" option, and you will regain access to your funds.
By default, MetaMask works with the Ethereum network, but you can add any EVM-compatible networks: Polygon, BNB Smart Chain, Arbitrum, Optimism, Avalanche, and many others.
The wallet itself is free. You only pay network fees (gas) when sending transactions. The fee amount depends on blockchain congestion.
Yes, MetaMask is decentralized software that works worldwide. There are no geographical restrictions. You can use it from any country.
Unfortunately, without the secret phrase, it is impossible to recover access to the wallet. That's why it's extremely important to write it down on paper and store it in a safe place. MetaMask cannot help with recovery — this is the principle of decentralization.
Go to the dApp website, click the "Connect Wallet" button, select MetaMask from the list. Confirm the connection in the wallet window — and you're ready to go.

Click "Add Token" in the wallet interface, enter the token contract address (can be found on Etherscan), and the token will appear in your assets list.
A transaction may get stuck if you set too low a fee (gas price). You can speed up the transaction in the MetaMask interface or wait for the network to clear.
No, transactions in the blockchain are irreversible. Always carefully check the recipient address and amount before sending.
If you have a secret phrase (12/24 words) from another wallet, select "Import Wallet" when starting MetaMask and enter your phrase.
