Hi dkbit98, it is indeed a Bitcoin-based project.

The Unisat and Hiro wallets are wallets that manage ordinals. Unisat is user-friendly, which is why I chose to integrate it first. Hiro and other ordinal wallets will come later.

In the long run, I would like to allow the use of the web app with any Bitcoin wallet, as long as it supports Taproot. (Although I have an idea in mind to work around the issue and open the game to everyone)

I hope I have answered your questions.
