Cons

Verdict

Currently definitely one of the best hardware wallets out there. Bluetooth connectivity allows for easy cable-free use. The built-in battery lasts a very long time – users typically don’t experience any low battery anxiety at all. The secure element chip prevents seed phrase extraction attacks, but comes at the price of closed source firmware. Users have to get familiar with the concept of individual apps that have to be manually installed by the user to make the device support the features (i.e. coins, security key functionality, etc.) they need. Installation is not much different than installing smartphone apps from the app store though, so not that difficult after all. As no company is perfect, please make sure to keep updated on Ledger controversies, before making a buying decision. Read more about Ledger controversies

All in all – a very good deal to keep your crypto assets safe with a very high level of security.

It is also important to note that whether a feature is a “pro” or “con” can depend on your situation and preferences. What may be an advantage in one scenario could be a challenge in another, and vice versa. Therefore, while reviewing these points, it’s essential to consider your unique requirements and circumstances when making decisions. This list aims to provide an idea of what to anticipate, but it is not the ultimate guide to determining whether something will work for you or not.

Proprietary method

Device does support the BIP-39 standard in the companion app. The proprietary CoolBitX mnemonic (seed phrases generated using the “on card” option) is based on BIP-39, but does not use the BIP-39 wordlist. Sample code that demonstrates seed and key generation is available in the CoolBitX Mnemonic Github repository.
