Yes, we use the industry-standard BIP39, as your crypto wallet does. Instead of using the BIP39 words we use the BIP39 numbers. Why? Numbers are easier to store in titanium than long words. Easy peasy.
NOTE: The order of the words and correlating numbers can not be changed. It is a standard, so you do not have to worry about this.

BIP39 is the open-source industry standard used by cryptocurrency wallets. It is an alphabetical word list of 2048 words.
The first word 'Abandon' is number '0001' The last word 'Zoo' is number '2048'. All the words in between also have a correlating number. Check out the list here.

Nope. We are good crypto citizens and use the industry-standard BIP39, just like your cryptocurrency wallet does.

The BIP39 wordlist can be found on Github and other sources on the internet. Of course, you can also find it on our website and in the included setup guide in your Zeus box. Once you have the BIP39 List, you can look up the words that belong to your numbers. This will take you 5 minutes.

No, if we all end up under a bus and close down our business you still can access your funds, because BIP39 is an industry-standard that can not be changed. This means you can always retrieve your recovery seed, with or without CRYPTOTAG or any other third party needed.

The Zeus enables you to store your BIP39 seed phrase. The majority of the wallets out there use the BIP39 protocol. Examples: Ledger, Trezor, Coldcard, Trust Wallet, Exodus, Electrum, MetaMask, and many many more...

Don’t just take our word for it...
