How to store seed phrases. Are you really safe?
How do you store your seed phrases?
If you put it on the cloud, you can't protect the seed phrase from the risk of network or hacking.
Is it okay if I write it on a piece of paper and lock it in my desk? What would you do if the paper burns in the event of a disaster such as a fire? What if I spill some ink? What if someone scribbles by mistake? What if I get wet?
While seed phrases are of utmost importance, until now there hasn't been much of an easier and more secure way to protect them.
But KeyTag solves all those problems.
  1. Protect your valuable asset seed phrases with aerospace-grade TC 4 titanium alloy

Titanium is a very safe material compared to paper and other physical storage methods for seed phrases. The aircraft grade titanium used for the Key Tag is

Hard but small and light

Titanium has only about half the weight of copper in terms of specific gravity. Thanks to that, Key Tag realizes a lightness of 14 g, while titanium, which boasts three times the strength of aluminum and twice the strength of iron, has impact resistance and so on, making it almost impossible to damage it.

Heat resistant and nonflammable for peace of mind even in the event of a disaster

The aerospace grade TC 4 titanium alloy used in the KeyTag can withstand heat up to 1668 degrees. With 7 times the heat resistance of tin and 2.5 times the heat resistance of aluminum, your seed phrase will be protected even in the event of a fire.
In Japan, it is also used as a noncombustible material for buildings such as Tokyo Big Sight.

Corrosion resistance that is safe even if it gets wet

Titanium is a material that is extremely resistant to rust, and will not rust or degrade when stored in a humid environment. Even if you accidentally spilled coffee on the seed phrase written on paper, or put it in the washing machine while it was in your pocket and the paper was torn, you can protect the seed phrase.

  1. Keep your seed phrases safer with punching games

Store your seed phrases using the enclosed word list and dedicated tools. If someone sees your memo, they can see the words themselves, but with Key Tag you don't have to worry about that. You can use it with peace of mind without worrying about the seed phrase leaking due to prying eyes.

  1. Supports seed phrases generated by major wallets

Compatible with BIP39 hardware and software wallets (e.g. Ledger Nano X, Trezor, Bitbox, KeepKey, Coldcard, MetaMask, Coinbase Wallet, Electrum, Mycelium, Exodus, Wasabi Wallet, Opolo, Cobo, ZenGo, CoinSmart, etc.).
