What is CryoSeed? – Review

As cryptocurrencies become more mainstream, so does the number of crypto investors and traders. With that in mind, crypto users need to have safe alternatives for storing cryptocurrencies. One of the best ways to safely store cryptocurrencies is through self-custody wallets. These wallets provide a seed phrase that you should keep with yourself in order to access and recover your funds.

However, these seed phrases are best kept in physical forms such as in a piece of paper. The reason for this is that keeping seed phrases in smart devices would make them vulnerable to potential hacks. So, keeping them physically is much safer. 

Nonetheless, you can easily lose a seed phrase if you keep it in a piece of paper, unless you keep it somewhere very safe. To make sure you keep your seed phrase as safe as possible, you can use seed phrase storages. One of the best seed phrase vaults, which proves to be quite practical at the same time, is CryoSeed.

In this article, we will review CryoSeed and its features, as well as explain its relevance in today’s crypto industry.

The main goal of CryoSeed is to facilitate self-sovereignty and provide you with a tool that makes your seed phrase recovery highly secure, reliable, and indestructible. 

Most crypto traders store their seed phrases written on a piece of paper since it is safer than keeping them in a smart device.

This is where CryoSeed is useful. Not only does CryoSeed encode your seed phrase into a set of points, but it is also made out of marine steel. The two metal plates can even be secured using any key or combination lock. A locked and encoded CryoSeed can seriously delay a theif from accessing your wallet. This gives you crucial time to move funds to a safe wallet in a worst case scenario. CryoSeed can endure extreme temperatures, is water proof, and corrosion resistant. 

CryoSeed is compatible with all BIP-39 self-custody wallets (software or hardware), including Ledger, Trezor, MetaMask, Exodus, Trust Wallet, and many more.
