REAL Security Inc. has challenged competing hardware wallets providers with their new cold storage device. The BC VAULT (short for Blockchain Vault) is a multi-crypto hardware wallet that generates non-deterministic wallets, enables easy and secure crypto transactions and offers encrypted backups by default.

Main Features:

  • Independently generated private keys: BC VAULT acts as a true random number generator (RNG) and
    can generate more than 2000 individual, non-deterministic wallets. Each private key is
    generated independently of another, meaning that no two keys are mathematically linked. If any
    wallet gets compromised, it cannot be traced back to other wallets in the BC VAULT. Each wallet
    can also be locked with a different PIN and passcode.
  • Encrypted microSD and paper backups: The BC VAULT provides long-term
    storage device that enables users to encrypt backups. Instead of having a single, unencrypted
    recovery seed, each wallet can be backed up individually on an unlimited number of secure
    memory cards or in the form of printed QR codes.  Each device already includes one 1GB
    microSD card.
  • Large display and D-pad: The 2.42-inch OLED 128×64-pixel display fits all important
    transaction details on screen to protect against a man-in-the-middle attack. The display shows
    full sender and recipient addresses, wallet name, crypto amount and fees (including warnings
    about unusually high TX fees). The 4-way control pad enables easy navigation and improved
    response.
  • Secure storage: Private keys are stored in FRAM, which has a 1000x faster throughput and
    consumes 250x less power than Flash. The chip prevents exposure of wallets to potential
    malware on connected devices and guarantees reliable data storage for over 200 years at 35°C
    (95°F). Firmware upgrade (certificate signed) is always done on non-active partition to prevent
    any errors from breaking down the device during the upgrade procedures.
  • Strong encryption: Each BC VAULT is pre-loaded with a private key that corresponds to a
    public address owning 1.0 BTC. As an act of confidence in the bullet-proof encryption, the bounty
    wallet is encrypted the exact same way as other BC VAULT wallets.
  • Multi-crypto and native ERC20 token support: The BC VAULT hardware wallet enables
    simultaneous use of multiple wallets and cryptocurrencies in a single app. It is also the first to
    support native storage of all ERC-20 tokens (more than 170.000). Without needing to rely on
    third-party applications or websites, users can manage BTC, ETH, LTC, BCH, BNB, DASH, XRP,
    XLM, and many other supported currencies.
  • Anonymity: Wallets on the hardware device are generated independently and cannot be traced
    back to a single device. The BC Vault also has no serial number, ensuring complete anonymity
    of its owner.
