As you know, in the latest Telegram updates, people can create a mini app (Telegram Mini App).
That is, you can create in-app applications in Telegram that make users have easy access to your product (for example, NOTCOIN, which you saw, even non-crypto users can enter without any problems).

Virtually all crypto areas such as Defi, NFT, Game, etc. can create their mini-apps and people can make transactions very easily.
This move is very stupid and it can be said that it was planned in advance because Wallet was talked about in the Telegram program much earlier 👀
