How secure is the eSignus wallet?

Our technology has been awarded twice by cybersecurity experts for its robust security features. Furthermore, industry leaders, such as Giesecke+Devrient, trust it. Our design also incorporates a comprehensive and innovative range of security measures to fully protect the keys and the assets management, ensuring the highest level of security in the cryptocurrency market.

What makes the eSignus Cold Wallet so remarkable?

Our hardware wallet stands out not only by including all the essential features typical of other cold wallets but also by offering innovative and unique functionalities that enhance user experience and security, such as:

  • Decentralized Recovery Process: Who hasn’t heard stories of people who bought Bitcoin at a fraction of its current value, only to realize years later that they lost their keys and the fortune they could have made by selling at market price? Our recovery process prevents this from happening, allowing users to recover their crypto just by ordering a new backup card whenever needed.
  • Multiseed: Before our cold wallet, if one had ten private keys, one would have needed ten devices to manage them with security. Nonetheless, our cold wallet manages an unlimited number of private keys and wallets, flipping the market at a very competitive price.
  • Crypto inheritance: Our twice-awarded technology allows users to pass on their inheritance securely without ever sharing their keys with heirs.
  • Easy of use: Our wallet allows users to sign transactions simply by tapping the card to a phone with NFC connectivity, providing a seamless and straightforward experience. This contrasts with the more cumbersome process of Ledgers wallets, the long-time market leader.
What’s a Cold Wallet?

A cold wallet is a physical device designed to store cryptocurrency private keys offline, protecting them and therefore, the associated funds from hackers. By keeping keys disconnected from the internet, cold wallets significantly reduce the risk of cyber-attacks. Some cold wallets, like ours, enable users to send, swap, sell, and buy cryptocurrencies directly, combining security with flexibility. This makes cold wallets an essential tool for anyone looking to safeguard their digital assets effectively.

Wealth Stored in Traditional Banks vs. Cryptocurrencies

The main difference between keeping money in a traditional bank and owning digital assets is that with the latter, the owner is responsible for the safety of their funds. Additionally, blockchain technology ensures that once a transaction is made, no one can reverse or modify it, not even if the money was stolen. Furthermore, if the keys get lost or stolen, so does the money.

Thus, crypto users need to take care of two main issues:

- Preventing Keys from Being Stolen by Hackers:
To mitigate this risk, the primary recommendation is to keep keys offline by storing them in a truly secured cold wallet. This keeps sensitive information out of reach from online attackers.

- Avoiding the Loss of Keys: We’ve all hidden something so well that we couldn’t find it again. In the crypto world, losing access to one's keys means losing one's assets permanently. This is why using a cold wallet like ours, with secure and accessible backup practices, is essential for managing digital assets safely.
