The New Tangem Wallet Seed Phrase Option | FAQs


In the past, we’ve chastised and campaigned against seed phrase technology. Our opinion on the security of seed phrases has not changed — the disadvantages are obvious.

However, the new Tangem Wallet will generate and show you a seed phrase (if you want one). It also allows you to import your seed phrase from another wallet.

Why does the new Tangem Wallet provide a seed phrase option?

To quote George Orwell, “If you want to keep a secret, you must also hide it from yourself.” In the past, hardware wallet users have often exposed, lost, or forgotten their seed phrases. Frankly speaking, our multiple-card private-key generation & storage technology is far more secure.

But in the spirit of independence and versatility, we decided to give our community the option to use a seed phrase. Tangem now provides a universal solution, allowing every crypto user to make their own security decisions.

Using this option opens you up to storing the seed phrase insecurely, but it does give an outlet to people who really want a seed phrase as a fallback in their imagined worst-case scenario.

FAQs: Tangem Wallet’s seed phrase option

We answer your questions about the seed phrase feature in the new Tangem Wallet. When we get more questions from our community, we'll answer them in this section. 

Does the Tangem wallet generate a 12 or 24-word seed phrase?
The wallet generates a 12 and a 24-word seed phrase. You can choose between both options.

Will the classic Tangem Wallet be produced in the future? Or will it eventually be replaced by a new one?
We have ceased production for the classic Tangem Wallet. The new Tangem wallet will eventually replace the classic wallet.

What's new about the new Tangem card design?
There is a new logo, style, and aesthetic; learn more about the new Tangem Wallet design here.

Can I choose 12 words for my seed phrase?
No, you can only import a seed phrase generated by another crypto wallet. 

If I forget my seed phrase, can I still add an extra card as a backup?
No, you cannot. Once you’ve generated and used a seed phrase, you cannot revert to generating private keys and using additional cards as your failsafe option.

How does the Tangem app generate and transfer the seed phrase to the Tangem card?
The wallet’s software selects 12 or 24 random words from a wordlist containing 2048 words based on the BIP39 seed phrase standard. 
The software converts the chosen string of words into a binary seed, which it uses to generate a set of private keys and public address pairings. The private keys are then uploaded and stored on the Tangem cards.

Can the seed phrase be used to restore wallets from a new set of cards?
Yes. You can access your funds by using a seed phrase previously generated on another set of new Tangem Wallet cards. 
When activating the wallet set on which you want to use the seed phrase, select Other options and then use the import seed phrase function.

Does the new Tangem Wallet support multiple addresses?
No, the new Tangem Wallet does not support multiple addresses yet. Before adding it, we’re still working to ensure this feature is secure and convenient. 
Once it’s ready, this feature will also be available for classic Tangem cards.

How does importing my seed phrase from another wallet work?
When you use the seed phrase import function from a third-party wallet, you can regain access to the funds that are stored in that wallet. You can import a seed phrase consisting of 12, 15, 18, 21, or 24 words.

After importing the seed phrase, you might have to manually add the coins and tokens you stored in the third-party wallet to Tangem by creating a custom token with a suitable derivation path. 

Please note that you'll only be able to recover funds from the third-party wallet on networks supported by the new Tangem Wallet. 

When will the new Tangem app be released on app stores?
The new app will be released in October 2023.

Can I use the new app with my classic Tangem cards?
Yes. All classic Tangem cards will be compatible with the new Tangem app.

What's the difference between the new Tangem wallet and the classic Wallet?
Both generations of Tangem cards work the same way to store your keys. However, the new Tangem card allows generating a seed phrase or importing one from another wallet. The new Tangem Wallet also has the option to turn off access code recovery with a backup card.

Will the new Tangem app be available on PCs?
No. The new Tangem app will only be available on NFC-enabled smartphones.
