Wallet functions

In the UX design, we were guided by the best practices
of leading crypto wallets that have already proven
effective and are familiar to many users.

Even if users are new to cryptocurrency, they will quickly
grasp how the app works. The screens are not overloaded
with information, and users always know what action is required.

additional traffic through a web version

Corporate identity

Designed the company
logo

For brand recognition, the company needed a
memorable logo. We settled on a friendly Godzilla image,
as “Kaiju” translates from Japanese as “giant monster.”

This is how Kaiju (company name) is translated from
Japanese.
