Frequently asked questions
Do I need to complete every item?
For anything you intend to hold long-term, yes — work through all of them. For a tiny, short-term experiment you're not serious about keeping, the risk is smaller, but items 4 and 8 (offline phrase, verify on the device) still apply to any self-custody, however small.
Where is my progress stored?
Only in this browser, on this device, and only if you tick "remember my progress." It's a convenience so you don't lose your place — it has no access to your wallet or keys, and it's never transmitted. You can clear it with Reset, or by clearing your browser's local storage.
I already made one of these mistakes. Now what?
If you photographed or uploaded your recovery phrase, delete every copy (including cloud syncs) and, to be safe, move your coins to a brand-new wallet with a fresh phrase — treat the exposed one as burned. If you sent to an unverified address, the transaction is likely irreversible, which is exactly why the test-transfer and on-device-verification steps exist. See scam awareness.
