What Is a BIP-39 Standard?
BIP-39 (Bitcoin Improvement Proposal 39) is a standard that describes the implementation of a mnemonic code or seed phrase to generate a deterministic wallet. It specifies the use of a list of 2048 English words to create a human-readable backup.
This standardization allows wallets from different providers to be interoperable, meaning a wallet can be recovered using the same seed phrase across various compatible software.
