NGRAVE is a digital asset and blockchain security company offering a secure and easy-to-use end-to-end solution for individuals and businesses to manage their cryptocurrencies with maximum peace of mind.
NGRAVE's purpose is to empower people and businesses financially and to aid them in taking true ownership of what is theirs.


2017. Xavier Hendrickx opens up the smart contract balance of SwarmCity’s ICO. He expects to see 44,000ETH ($10M at the time). Instead, the balance is empty. Everything is gone. With some fellow ethical hackers, Hendrickx figures out the exploited vulnerability. In the next 48 hours, they attack 500 other blockchain projects, secure $208M worth of crypto, and return the funds to their rightful owners after the vulnerability is fixed. In Hendrickx, a passion for security is ignited.

April 2018. Ruben Merre, Edouard Vanham and Xavier Hendrickx are three crypto investors that know how it feels to be hacked. That, just like the vast majority of users, know how it feels when you log in to your exchange account and for a moment you only feel anxiety on whether your balance won't say zero. The three ask themselves a very simple question: “Which solution would we trust with our first till our very last bitcoin?”. No answer. They decide to build it themselves. NGRAVE is born.

2018 - 2020 Most of the design, development, and industrialization phases take place in the next two years. NGRAVE is particularly adept in surrounding itself with strategic partners that are in the top tier of their niche worldwide. Examples include the world leading R&D and innovation hub for nanoelectronics, sensor technology and chip manufacturing, imec, also known for taping the first atom-size (3nm) chip in the world. Imec's istart Fund invests in NGRAVE and also offers its expertise to build NGRAVE's product suite from the ground up. Moreover, COSIC, the world's leading research group for applied industrial cryptography, known for inventing the world's Advanced Encryption Standard (AES 256), and recently selected as the winner of NIST's 4-years long post-quantum cryptography standard competition, becomes a strategic partner of the company. Many other thought leaders join the endeavor, including Prof. Dr. Jean-Jacques Quisquater, legendary cryptographer and second reference of the Satoshi 2008 bitcoin paper.

June 2020. NGRAVE launches its pre-orders on Indiegogo, raising $450,000 in one month(2), posting the most successful coldwallet crowdfunding campaign in history, besting 15 hardware wallet projects that did a similar crowdfunding campaign before them, and with a 9X on the second best wallet campaign, which raised $50,000.

2021. NGRAVE has successfully developed and industrialized the world's top tier solution for managing crypto securely and seamlessly. NGRAVE starts raising its Series A funding round.


NGRAVE offers the first true end-to-end solution for users to manage their crypto, with a product suite that provides an effective answer to all the what-ifs in a crypto user’s customer journey, from fiat-crypto onramp (the first purchase of one's crypto) to inheritance planning (making sure that the next generation can easily and safely inherit the user's crypto portfolio). A central metric is the user’s peace of mind, measured by NGRAVE’s Peace of Mind index.

The product suite consists of:

ZERO - “The Coldest Wallet”: The most secure and easy-to-use hardware wallet in the industry.
          ○ 100% offline, removing all online attack vectors.
          ○ The only solution in the financial services industry with an EAL7 security certification, the highest in the world.
          ○ Built from scratch to be tamper resistant.
          ○ High-end, seamless touch screen device experience, with the user’s coins always “just one tap away”.
GRAPHENE - “The Coldest Backup”: A key backup solution that covers all the “what-ifs” in the user’s journey:
           ○ Resistant to extreme circumstances (e.g. a house fire).
           ○ Encrypted: undecipherable if found by a 3rd party.
           ○ Recoverable: can be restored when lost.
           ○ Inheritable via secure, easy recovery mechanisms.
LIQUID: Mobile app enabling the last-mile communication with the blockchain:
           ○ Communicates with ZERO through one-way QR codes. After syncing, the user can consult and manage his portfolio in real-time. Private keys remain offline.
           ○ Plug & play: replaceable by any 3rd party hot wallet.
