Mnemonic

A mnemonic phrase, in Web3 wallets, is usually a set of randomly generated words that users use to regain access to their wallets. These words typically number between 12 and 24, helping users securely manage and access their digital assets. The generation of mnemonic phrases follows industry standards (such as BIP39) to ensure their security and randomness.

The main function of a mnemonic phrase is to simplify a complex private key into a form that is easy to remember. A private key is a secret key that only its holder can use to access and manage the corresponding wallet and its assets. By using a mnemonic phrase, users can conveniently restore their wallets in case their device is lost or damaged, thereby protecting the security of their assets.
