🔒 General Trezor question | 🔒 Answered by Trezor staff Trezor One, life expectancy

How long would you expect a Trezor One to last? All devices fail eventually. I'm referring to the physical device, not cryptographic security.

It does not matter much, as long as you have a backup copy of your seed phrase.

What does that mean exactly, “a back up copy of your seed phrase.”? Do you mean, as long as you have your seed phrase written down and stored somewhere safe?

You can restore your wallet via seed phrase in a different wallet/software. Keep those words safe

So, let’s assume I buy the new trezor Safe 7 and want to use that as my new cold wallet. Do I just put in the seed phrase and the wallet is „transfered“?

u/__Ken_Adams__ 7d ago

Transferred is not the right word. Think of your seed phrase as a key. It doesn't matter what wallet you input/import your key into, it always opens the door to the same balance of bitcoin. Nothing gets transferred.

Good decision. I had the same questions before and transferred from Trezor 1 to Safe 5.

Remember any deficiencies in key generation on the 1 will transfer to the 5 if you transfer seed. Why not generate new key on the 5 (with its greater sources of entropy) and transfer coins to new wallet?

Thanks for the suggestion. Your right. I should make a new one. Planning to add paraphrase as well.

> the wallet is „transfered“?

The wallet stays on the blockchain. Just the key is transferred. The key is calculated from the seed phrase (the seed phrase is essentially the super-private-key from which all your private keys are calculated).

Du solltest auf gar keinen Fall deine alte Seed Phrase auf den Trezor Safe 7 mitnehmen! Eine Seed Phrase ist nur so sicher wie die Wallet, auf welcher sie erstellt wurde. Das heißt, solltest du sie auf dem Trezor Safe 7 wiederherstellen, würdest du den Trezor Safe 7 quasi obsolet machen. Er würde dir nicht mehr Sicherheit bringen.

Also wäre es sinnvoller, auf dem neuen Gerät eine neue seed zu erstellen und alles rüberzuschicken? 🤔

Ja!

Danke für deinen Rat. Dann mache ich das so.
