Opendime Bitcoin hardware wallet

On their website, Opendime is referred to as the “World’s First Bitcoin Credit stick wallet.” The highly innovative and minimalistic USB stick allows users to load Bitcoins onto the wallet and physically pass them to other users multiple times. It deviates from the traditional security protocols used by both software and hardware wallets.

For instance, it does not need to be secured with a PIN, and neither does its contents need to be encrypted. And unlike most other crypto hardware wallets, Opendime doesn’t have a screen or transaction confirmation buttons. Rather, you have to connect it to your computer to check crypto balances.

In this review, we want to determine if the Opendime hardware wallet is indeed the most secure Bitcoin vault yet. And to answer this, we explore different aspects of the wallet, including its ease of use, set up process, pros, and cons, and also compare it with other hardware wallets.

But first, we look at how Opndime works.

How Opendime hardware wallet works

Like most other hardware wallets, Opendime is a USB-like device that’s specially designed to store Bitcoins. Every time you order Opendime, you will receive a set of three single-use wallets. Single-use here implies that you can only draw coins from the wallet once. After receiving the wallet, you can add as many bitcoins for as long as possible. But to access these coins, you need to break the special seal on the device.

Opendime key features:

Highly versatile wallet: Opendime is a highly versatile and easy to use hardware wallet. It is compatible with a computer, laptop, or even a phone. Simply plug it into either of these devices to initiate the setup process, check balances, or withdraw the bitcoins stored therein.

Free to use: When using the standard hardware or software wallet, you are often required to send bitcoins over the blockchain network. The process isn’t just time-consuming, but you also have to pay network fees for the online transaction. When using Opendime, you can copy coins from one wallet and transfer them to another, physically, without incurring the Bitcoin network fees. You also don’t have to wait for hours on end to have your transactions processed.

Bitcoin-specific: This implies that unlike most other hardware wallets like Trezor or Ledger Nano S that host thousands of cryptocurrencies and tokens, Opendime can only support Bitcoins.

Opendime security features:

Keys are generated by the device: Your Opendime wallet will automatically generate the private and public wallet keys as well as your address QR code. These unique wallet identifiers are created as soon as you plug your device into a computer and are highly randomized to eliminate duplicity.

No access to private keys: After the private wallet address is generated, it is stored within the device. Not even the wallet owner can view the private address without having to break the wallet’s seal.

Tamper proof: According to Opendime creators, Coinkike.inc, it is impossible to tamper or duplicate these hardware wallets. They argue that the wallet is designed using proprietary technology, where each chip contains a unique factory key that is impossible to peel or replace.

While Opendime only has one layer of protection over a client’s private keys, Ledger Nano S embraces a multi-layered security approach.
