If you roll your own seed, you do it so you don't have to trust a random number generator. But does the SeedSigner really turn your 99 rolls into the right 24 words? Until now, checking that meant running a Python script in a terminal.
Dice Check is a single HTML file: save it, switch off Wi-Fi, double-click, type in the digits. No server, no connection, no third-party code. Word list verified by hash, SHA-256 computed twice, self-test on start. Free, MIT-licensed, checksum on the page.
One rule, no exceptions: never enter your real seed. You test the method with a throwaway seed, then discard it. If the device gets practice digits right, it gets everything right. The digits in the picture are the example from the SeedSigner docs.
A tool from the workshop pack for the upcoming volume 4 on Bitcoin self-custody.
