A string used to generate a private key.
A wallet seed is a unique sequence of words, numbers, or a mnemonic phrase that serves as the root for generating cryptographic keys in a cryptocurrency wallet. Some blockchains use only one of the aforementioned key sequences, such as XAMAN (formerly XUMM) uses only numbers. It is a crucial piece of information that allows users to recover their wallet and access their funds if their device is lost, stolen, or damaged. The wallet seed ensures the security and portability of cryptocurrency holdings by enabling easy backup and restoration of wallet information across different devices or platforms.
