The whole ceremony, start to finish, with nothing hidden.
Insert the stick and restart the computer, choosing the stick as the boot device. Your installed operating system never loads. Keyloggers, clipboard monitors, and screen-scrapers on that machine never execute, because the environment they live in is not running.
The stick asks for entropy of your own — dice rolls, or a long burst of keystrokes. This is blended with the hardware source rather than replacing it, so that either source failing on its own still leaves the key strong. This is the single control that saved Coldcard users in 2026.
Your seed phrase appears once. Twelve or twenty-four words, numbered, plus your Solana receive address. Copy them by hand. Then the stick asks you to type several of them back before it will show you anything else.
When you are done, power the machine off. The key existed only in RAM. There is no file to shred and no cache to clear, because nothing was written anywhere at any point.
Boot your normal operating system. Send a small test amount to the address you wrote down, confirm it arrives, then fund it properly. Keep the paper somewhere a flood and a fire cannot reach at the same time.
Once the ceremony ends, one hundred per cent of your risk lives on that piece of paper. We cannot help you if it burns, and we cannot help you if someone reads it. There is no reset, no recovery, and no support ticket that can undo either. That is not a gap in the product — it is the entire point of it.
