Our verdict
NGRAVE is a hardware wallet for holders who want their own keys kept offline and can absorb a €398 outlay, ranking 116 of 120 on price. The EAL7-certified secure element is the reason to look here, and coverage of 3,500 coins rounds out a device built for storage rather than spending.

Pros and cons
Pros
- Full self custody, so the owner signs every transaction and no provider holds the balance.
- A EAL7-certified secure element does the signing, which is the reason many buyers pay more.
- Coin coverage of 3,500 ranks 10 of 108 on this site.
Cons
- The €398 device price is the heaviest outlay here, against Trezor at $79.
- The firmware is not open source, so buyers cannot read the code themselves.
- Support runs on email, help centre and community only.
Who it suits
- Holders of larger sums who want self custody with keys kept offline.
- Buyers who shop on chip security rather than on the lowest device price.
- Owners of a wide coin set, since 3,500 coins are supported.
Who should look elsewhere
- Trezor buyers on a tight budget, since Trezor costs $79 against NGRAVE at €398.
- Bit2Me users who want a mobile wallet for spending rather than cold storage.
- bynex users who prefer custodial accounts to holding keys themselves.
How your money is protected
NGRAVE keeps keys in self custody, so the owner signs transactions on the device rather than handing them to a provider. The EAL7-certified secure element handles the signing and is built to resist physical attack, which is the core of the pitch. The firmware is not open source, so readers who want to inspect the code have to look elsewhere.
The company behind it
NGRAVE is run by Hestara SRL, based in Belgium and founded in 2018. Support comes through email, help centre and community, so written answers and community threads carry the load. The company is a hardware specialist, which fits a product built around a secure element.

Frequently asked questions
How much does the NGRAVE cost?+
The device is priced at €398, a hardware cost paid up front rather than a recurring charge. That places NGRAVE at 116 of 120 on price in this comparison, above cheaper hardware such as Trezor at $79.
Does the NGRAVE keep my coins offline?+
It does. Custody is self custody, so the private key stays on the device and transactions are signed on the hardware. Nothing depends on a provider holding a balance for you, which suits holders who want sole control of the keys.
Is the NGRAVE firmware open source?+
It is not. The firmware is not open source, so the code that runs the device is not published for outside inspection. The security case rests on the EAL7-certified secure element instead, which is a hardware property a buyer can check on paper.
Which coins can the NGRAVE hold?+
Support covers 3,500 coins, which puts NGRAVE at 10 of 108 in the ranking on coin count. That is well above the hardware wallet median of 345, so long lists are not a problem.
How do I back up the NGRAVE?+
Back-up is by seed phrase, so recovery rests on that phrase rather than on a set of shares. It is the only route back into the wallet if the device is lost, which makes careful storage of the phrase the buyer's own job.
How does the NGRAVE connect?+
Connection is by usb c only, so signing needs a cable and a compatible computer. Nothing in the connectivity list points to Bluetooth or NFC, which suits people who would rather keep a wireless radio out of a key holder.
How do I get help from NGRAVE?+
Support runs through email, help centre and community. That means written answers, a help centre and community threads, with no phone line for urgent questions. It suits self sufficient buyers, less so people who want live chat when a transfer is stuck.
Who is the NGRAVE for?+
It is built for long term holders who want self custody and will not touch the device daily. For day to day spending a mobile wallet such as Bit2Me is quicker, and bynex is custodial for people who prefer someone else holding the keys.
