How do you use Trezor?
- Buy from the maker's official site, typed by hand into the address bar (never via an ad or a marketplace).
- Check the domain before paying and reject any unit sold "as new" by third parties or with a seed already printed.
- Choose "create new wallet" and let the device generate the words itself; never use a ready-made seed someone gave you.
- Write the words by hand, numbered and in order, on paper; for the long term, engrave them in metal.
- Confirm the backup on the device, and never photograph the seed, type it into a website or store it in the cloud.
- Test recovery with a small amount before moving anything significant.
- Set a strong PIN and leave the passphrase until you master the flow, keeping its backup apart from the seed.
What are the limits and cautions?
- Trezor publicly stated it is not affected by the 2026 Coldcard seed flaw; that is the maker's own statement, and the book stresses that no hardware wallet is perfect.
- This site uses a Trezor affiliate link and may earn a commission at no extra cost to you; it does not change the assessment above.
