MetaMask is a mainstream software crypto wallet launched in 2016 by ConsenSys. The wallet currently supports browser extensions and mobile apps. MetaMask can be used to store/transfer crypto assets, interact with blockchain networks and decentralized applications (DApps), etc. Currently, MetaMask supports all EVM-compatible networks, such as Ethereum, BNB Chain, Avalanche, Polygon, Fantom, Arbitrum, Harmony, xDAI, etc.
The main features of MetaMask (also the features of most decentralized wallets) are as follows:
- Self-custody, different from custodial wallets, MetaMask It is managed by the user himself and no other institution has the right to access/control the user's wallet.
- Users can manage wallets through passwords, private keys, mnemonic phrases (Secret Recovery Phrase), etc. When users set up their wallet for the first time, they are given a mnemonic phrase, similar to a password. Mnemonic phrases are 12 unique, unrelated phrases. If the user's password is lost, the wallet can be retrieved through the mnemonic phrase.
- Users do not need any personal information to use MetaMask.
- Users can create and manage multiple accounts using the same mnemonic phrase in the wallet, and each account has a different address.
