This kit comes with the SEEDER in its case and a set of dice, so you can generate your entropy by hand from day one.\u003c\/p\u003e\n\u003ch3\u003eYou bring the entropy\u003c\/h3\u003e\n\u003cp\u003eThe SEEDER has no random number generator. You roll the dice (50 rolls for 12 words, 99 for 24) or flip a coin (128 or 256 flips), and the SEEDER does the BIP39 maths in front of you, including the checksum that gives you the last word.\u003c\/p\u003e\n\u003ch3\u003eVerify it, don't trust it\u003c\/h3\u003e\n\u003cp\u003eThe \u003cem\u003eEntropy (hex)\u003c\/em\u003e screen shows the exact bytes your words come from, so you can redo the maths with any offline BIP39 tool. Dice mode uses the same scheme as the Coldcard (SHA-256 of your rolls), so you can even check it from a terminal. If the words don't match, don't use the device.\u003c\/p\u003e\n\u003ch3\u003eTake it to your wallet\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eExport QR\u003c\/strong\u003e with your 12 or 24 words.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWatch-only QR\u003c\/strong\u003e with the account zpub, ready to scan into Sparrow Wallet so you can check your balance without exposing the seed.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNothing leaves the device\u003c\/h3\u003e\n\u003cp\u003eYour seed only lives in RAM and disappears when you unplug it.
