Our verdict
NGRAVE suits holders who want crypto in their own hands and can fund a €398 outlay up front. Keys stay with the owner, guarded by a EAL7-certified secure element chip, and support spans 3,500 coins, though the seed backup rests on a single secret and the price is steep next to $79.

Pros and cons
Pros
- self custody keeps the keys on the device, so no provider can move them
- Signing runs inside a EAL7-certified secure element chip rather than an exposed board
- A single device covers 3,500 coins, well past the typical short list
- A seed backup the owner records and stores themselves
Cons
- The firmware is not open source, so the code cannot be read by others
- Support runs on email, help centre and community, with phone support not among them
- A seed backup puts the whole wallet behind a single seed phrase
Who it suits
- Holders moving savings onto a device they control outright
- Buyers who will fund €398 up front rather than pay a running fee
- People who will not touch the keys again after the first setup
Who should look elsewhere
- eToro, if a mobile wallet covers what you need and hardware is overkill
- VaultLeap, if a mobile wallet suits you and holding a seed phrase is a drawback
- Trezor, if $79 buys enough security and open source matters to you

Frequently asked questions
How much does the NGRAVE wallet cost?+
It is a purchase of €398, with no account fee or subscription added later, so the outlay happens once at the point of buying. Against Trezor at $79, that gap is the main number to weigh.
Who holds the coins on an NGRAVE wallet?+
You do. It is a hardware wallet running self custody, so the keys sit with the owner and no provider can shift them. The other side of that is that no third party can restore access for you if something is lost.
What protects the device from tampering?+
Keys are used inside a EAL7-certified secure element chip rather than on a general purpose board, so the sensitive work stays in a certified part. The firmware itself is not open source, which leaves inspection to the manufacturer.
How is the wallet backed up?+
With a seed backup. That means the whole wallet rests on a single seed phrase, so where you write it down and who can see it matter more than most settings. There is no second share to split.
How many coins can the wallet hold?+
The published figure is 3,500 coins, which reaches well down a long tail rather than stopping at major names. Support follows the firmware, so check the list against the coins you plan to hold before committing to €398.
How does the device connect?+
Over usb c, so a computer has to be present for each signing request. That slows routine transfers and rules out a phone only workflow, which is the trade for keeping keys offline.
Who runs NGRAVE and how do I get help?+
The product comes from Hestara SRL, registered in Belgium and founded in 2018. Support runs on email, help centre and community, so expect to work through the help centre, email or community rather than a phone line.
