Can the NGRAVE “Perfect Key” be converted into 24 words?
Last updated December 16, 2023 19:45
Yes. The hexadecimal “Perfect Key” can be converted to a 24-word format and back again. Both formats represent the same 256-bit private key.
-
ZERO lets you view either format. Open Settings → Display secret key, enter your PIN code and then select Mnemonic or NGRAVE wallet.
-
If you need to perform the conversion yourself, this tool can be used: https://iancoleman.io/bip39/
NEVER enter your key into this tool while online!
Online use carries the risk of intercepted traffic or a website recording private-key data, which could put your funds at risk. Download the tool and run it locally instead. Ideally, never type your backup into any computer, and only use the converter when absolutely necessary. For the strongest security, consider moving funds to a new wallet afterward.

Could customs duties apply to my order?
At present, import fees do not apply to shipments within the EU or to qualifying orders in the U.S. (under 800 USD), Australia (under 1000 AUD) and New Zealand (under 1000 NZD). Local customs rules can change.
We take steps to reduce the chance of customs delays, but some destinations may still require the recipient to pay import charges before the parcel is released.
Orders ship from Belgium, so deliveries outside the European Union may be subject to customs duties or fees. These charges are not included in the purchase price and must be paid by the buyer to the carrier when required.
Charges differ by country. Contact your local customs authority for exact information.
Examples of countries that may charge import fees include (this is not a complete list):
-
United Kingdom
-
Canada
-
Switzerland
-
UAE,
-
Israel
-
Kuwait
-
Mexico
-
Singapore
