What's the current state of art of gamefi in TON? aside tonight, is there any other project ?

Nvm, there is a section in ton.app

For example:
https://t.me/fanton_nft_en
https://t.me/TONPunksENG

+ Infra:
https://tonplay.io/
https://engine.8xr.io/#web3

Tks! Will check them out

We are also working on TypeScript gamefi sdk for TON, which will make it easier to work with jettons, accept payments in jettons, etc.
You can take a look at alpha version here: http://github.com/ton-community/gamefi-sdk
