About this app
Your entropy enters the lab
Create. Derive. Verify.
Turn entropy you bring — dice rolls, playing cards, a number in any base, a seed phrase, or a private key — into a BIP-39 seed, then derive its master fingerprint, extended public keys, and receive addresses. The dice methods match COLDCARD, SeedSigner, Keystone, and BitBox, so the same rolls reproduce the same seed on those signers. This does not invent entropy — it is a calculator, and nothing leaves this app.
