Design and Build Quality

The Opendime is designed to be simple, compact, and secure, offering a unique way to handle Bitcoin transactions.

Compact and Portable Design The Opendime resembles a small USB stick, making it extremely portable. Its compact size allows it to fit easily into a pocket, wallet, or bag, making it convenient to carry and use wherever you go. The lightweight design ensures that it can be transported without hassle.

Durable Construction The device is built with durable materials, ensuring it can withstand everyday use. Its robust construction protects it from physical damage, making it a reliable option for securely storing and transferring Bitcoin.

No Setup or PIN Required One of the standout features of the Opendime is its simplicity. There is no need to set up an account, create a PIN, or download any software. You simply load Bitcoin onto the device and it’s ready to use. This plug-and-play functionality makes it accessible even for those who are not tech-savvy.

Tamper-Evident Design The Opendime is designed to be tamper-evident, meaning that once Bitcoin is loaded onto the device, the private key remains hidden until the device is physically opened and tampered with. This ensures that the Bitcoin remains secure and can be trusted as long as the device shows no signs of tampering. The physical opening process effectively destroys the device, which is a security feature to ensure the integrity of the stored Bitcoin.

Offline Transactions The Opendime supports fully offline transactions, adding an extra layer of security by eliminating the risk of online attacks. Transactions can be completed without the need for an internet connection, making it an ideal choice for those who prioritize privacy and security.

USB Connectivity The Opendime connects to any computer via USB, allowing users to easily check the balance and transfer Bitcoin when needed. This universal connectivity ensures compatibility with various devices, enhancing its versatility.

 

Security Features

The Opendime offers several robust security features, making it a secure choice for managing and transferring Bitcoin.

Tamper-Evident Design The most notable security feature of the Opendime is its tamper-evident design. Once Bitcoin is loaded onto the device, the private key remains hidden and inaccessible until the device is physically tampered with. Any attempt to open the device will be immediately noticeable, ensuring the integrity of the Bitcoin stored within.

Offline Transactions Opendime supports fully offline transactions, significantly reducing the risk of online attacks. By keeping the device disconnected from the internet, users can protect their Bitcoin from hackers and malware. This offline capability is crucial for maintaining the highest level of security.

No Setup or PIN Required Unlike other hardware wallets that require PIN codes and setup processes, the Opendime does not need any such procedures. This simplicity reduces potential security vulnerabilities associated with PIN management and account setup, streamlining the process while maintaining security.

Physical Bearer Instrument Opendime functions as a physical bearer instrument, similar to cash. The device itself holds the Bitcoin, and ownership is transferred by handing over the device. This physical aspect ensures that Bitcoin is only accessible to the person in possession of the device, providing a straightforward and secure method of transfer.

Private Key Generation The private key for the Bitcoin stored on an Opendime is generated within the device itself and never exposed to any external system or software. This ensures that the private key remains secure and protected from potential leaks or breaches.

Multi-Device Verification Users can verify the balance and authenticity of an Opendime on multiple devices without exposing the private key. By connecting the Opendime to a computer via USB, users can check the balance and transaction history securely.

One-Time Use Design The Opendime is designed for one-time use, meaning once the private key is accessed and the device is tampered with, it cannot be reused. This ensures that the Bitcoin is transferred securely and eliminates the risk of reusing a compromised device.
