The Cuvex self-custody system is a comprehensive suite of hardware, software, and fully decentralized networks that empower users regardless of their technical expertise with all the essential tools to manage the security, privacy, and sovereignty of their crypto assets. Whether you already have a wallet and, consequently, a seed phrase to safeguard, or you're a newcomer stepping into this exciting space for the first time, Cuvex provides robust solutions that enable you to securely and easily handle self-custody. Advanced privacy concepts are seamlessly integrated by design, ensuring processes that benefit you are automatically implemented, even if you're unaware of their inner workings. Facilitating the self-custody of your seed phrase, enhancing your transactional privacy on BTC, and helping you ensure your crypto assets are securely passed on to your heirs when you're no longer able to enjoy them all in a 100% decentralized manner are just some of the core objectives of the 360° Cuvex self-custody system.

Cuvex is an offline encryption and signing device, meaning it has no connection to the internet or any other device, and operates 100% offline. The Cuvex system offers comprehensive support so that anyone, regardless of their knowledge or experience in the crypto sector, can: Create and manage a seed phrase recovery process for any wallet, with high-security redundancy and low cost. It encrypts the seed phrase using AES 256 GCM, creates backups, and stores these cryptograms on NFC cards. A patented system that eliminates the need and risks associated with storing seed phrase backups on paper or steel. Create a 100% offline BTC wallet, participating in the entropy process of the seed phrase manually and physically, using the "Dice and Coin" standard, which ensures the highest quality seed phrase creation. Software-generated seed phrase creation systems have already made too many errors, with cases where software iteration and recurrence have been proven. Manage the wallet via the Cuvex Smartphone App "Watch Only Wallet," with privacy features like "Coin Control," maximizing privacy by design. Whether the user has knowledge or not, address creation and tracking is always tagged, allowing the establishment of observers, reasons, and future value data. It allows creating as many accounts as needed, and among many other processes, it enables freezing UTXOs for proper privacy management. All of this is done in the simplest and easiest way for all types of users. Sign transactions with Double AirGap PSBT. This process ensures the physical separation of 100% offline components required to move funds. The Cuvex hardware device does not store any user data. The Cuvex app only manages "Watch Only Wallet" processes and does not require user account creation or the submission of any personal data. The AirGap PSBT function is actually Double AirGap. The app configures the unsigned transaction and records it on an NFC card. This card is read by the Cuvex device for the "1st AirGap," and once verified on the Cuvex device, it requests the NFC card where the wallet's private key is encrypted for the "2nd AirGap." Upon signing the transaction, all data is deleted from the device. The same device can manage unlimited wallets, as it does not store private keys, unlike all other market options.

We’ve worked hard and innovated to address this concern. We have developed a desktop application that enables the decryption of any cryptograms created with version 1.1.0 or later of the Cuvex device firmware, without requiring a Cuvex device. Complete independence! All you need to do is download the desktop application from our GitHub . You also have the option to download the complete source code for the desktop application as an additional backup. This solution gives you complete independence from Cuvex for the future. However, it’s essential to strictly follow the app verification steps and make sure you’re installing and running the original, unaltered software.
