About BIP39
BIP39 specifies how to encode random entropy as a human-readable mnemonic from a fixed list of 2048 English words, with a built-in checksum. The mnemonic plus an optional passphrase derives a 512-bit seed used to generate hierarchical deterministic wallets (BIP32). All operations run locally — never share your mnemonic.
