- 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 Settings → Display 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: https://iancoleman.io/bip39/
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.
- Can I buy NGRAVE products via resellers such as Amazon?
You can only order your ZERO in the NGRAVE webshop or Amazon US (COMBO). At this moment we don't work with any resellers.
If another party than NGRAVE offers you to buy a ZERO do not give them your money. In case of doubt, always consult with us via support@ngrave.io. - Will I have to pay customs duties?
No import fees apply for shipments to the EU, the US, Australia and New Zealand
We took all measures to lower the odds of your package getting stuck at customs. However, some countries will require the recipient to pay additional import fees before releasing the package.
We ship from Belgium, so customs duties or -fees may apply to deliveries outside of the European Union. Customs duties and -fees are not included in the price and will have to be paid to the carrier by the buyer upon delivery.
The amount to pay varies from country to country. For more details, please contact your local customs authority.
Some countries that we know charge an import fee (this list is non-exhaustive):
United Kingdom
Canada
Switzerland
UAE,
Israel
Kuwait
Mexico
Singapore
