Introducing the Coinvest Hardware Wallet:

Coinvest Announces Premium Hardware Wallet with Innovative Design and Architecture to Securely Store Cryptonized Assets
The Coinvest hardware wallet complements the Coinvest decentralized investment trading platform and offers a single integrated solution to securely invest and store cryptonized assets.

DALLAS, TX - Coinvest, an emerging blockchain startup comprised of Microsoft alumni, is announcing the details of their hardware wallet that offers consumers a secure end-to-end solution to complement the Coinvest decentralized investment trading market for cryptocurrencies.

The Coinvest hardware wallet offers state-of-the art design and architecture featuring:
-  A cryptographic coprocessor with secure hardware-based key storage and asymmetric and symmetric cipher support
-  Linux operating system using a SAMA5D2 pre-PCI certified processor
-  4.3” LED backlit full touchscreen display with 480x272 resolution
-  FIDO/U2F support to use COIN wallet as a security token for two-factor authentication
-  A single USB-C connection with support for authenticating desktop and mobile devices
-  A dedicated screen and authentication chip to protect consumers even if the host computer is infected with a virus or malware
-  Support for Bitcoin, Bitcoin Cash, Ethereum, ERC20 tokens, and more

Unlike current solutions on the market that leverage pure MCU-based solutions such as the Ledger and Trezor, Coinvest has chosen a pre-PCI certified processor to mitigate the security risks that competing platforms possess, while maximizing graphics capabilities for an experience that is second to-none. The wallet also has a single USB-C connection with support for authenticating desktop and mobile devices. With premium materials and a size equivalent to a credit card, the Coinvest wallet provides consumers an all-in-one portable personal security solution in a strikingly beautiful design.

The Coinvest hardware wallet integrates with the Coinvest investment trading platform to offer an end-to-end solution to securely invest and store cryptonized assets. In addition to the storage of popular cryptocurrency protocols such as Bitcoin and Ethereum ERC20 tokens, the wallet will have an integrated password management application and FIDO/U2F support to use the wallet as a security token for two-factor authentication. The Coinvest wallet development API will empower developers to build secure apps to use with the wallet as well as offer compatibility with other leading wallet solutions such as MyEtherWallet, MyCrypto, and more.

Alongside the hardware wallet, Coinvest will be offering a case for device protection. The hardware wallet case features three slots to hold credit cards with one slot as an option for the modular money clip. Two fitted magnetic slots secure the hardware wallet and travel cable in place. The case features a variety of premium textures and colors to fit all personal styles. The combination of the Coinvest hardware wallet and case offers a single solution to carry cash, credit cards, and cryptocurrency together in a package slightly larger than the size of a credit card.

Coinvest is partnering with leading hardware and security firms, Cardinal Peak and Cryptotronix, to bring the wallet to market by early 2019. The Coinvest wallet will retail for $249 and only be available for purchase using the Coinvest COIN token direct from the Coinvest website. COIN is currently available for purchase during Coinvest’s token sale through Friday, April 6th at 9:30 CST. For more information, visit

From your website:

Enhanced Security
Secure hardware-based key storage and asymmetric and symmetric cipher support.

What do you exactly mean?
Asymmetric encryption on the hardware device? What for? How to decrypt it afterwards? Typing in a private key?  Huh

And what kind of encryption algorithms are used (can be chosen) ?

I got 4 additional questions:

1) How much storage does your device have?

2) "Hundreds of currencies" is mentioned.. how is the device protected from injecting code into the memory?

COIN owners can:
  • Create investment transactions and portfolios in Coinvest
  • Receive assets from investment portfolio profits and index fund investment fees
  • Purchase goods and services from merchant partners
  • Buy and sell on supported cryptocurrency exchanges

Does this mean you actually have to buy/own the HW wallet AND your erc20 token to use the wallet?  Huh

4) Is it open source? I didn't find anything regarding source code.
