Yes, the standard BIP-39 English wordlist: 2048 words, the exact same list Bitcoin wallets use. We generate phrases with @scure/bip39, an audited open-source library. No custom wordlist and no homegrown crypto.
The list is designed for writing down by hand: the first four letters of every word are unique, so a smudged or abbreviated word is still unambiguous, and similar-looking words were deliberately excluded.
Because it is the standard list, you can verify your phrase against any public BIP-39 reference, and our encryption layer is published as open core so you can check the implementation yourself.
