    The ZERO was developed to simplify the integration process so that additional cryptocurrencies can be easily added in the future.

  • Can I convert the NGRAVE "Perfect Key" to 24 words?

    Last updated December 16, 2023 19:45

    Yes. The hexadecimal “Perfect Key” can easily be converted into the 24-words version and vice versa. Both are alternative representations of a 256-bit private key.

    • On the ZERO, you can easily see both versions. Go to SettingsDisplay secret key, enter your PIN code and then select Mnemonic or NGRAVE wallet.

    • If you need to do the conversion yourself, you can use this tool: 

    NEVER USE THIS TOOL ONLINE with your key!

    There is always a risk that your communication is intercepted or the website logs your private key data, which might result in your funds being stolen. You should always download this tool and run it on your own computer. Best practice is that your backup is never entered on a computer. So only use this tool when you need to. We recommend to move your funds to a new wallet afterwards to preserve optimal security.
