Finally, the developers at $TON have been pleased as well. Now STON.fi SDK has a convenient demo application, which developers can use as an example to implement swap functions in their application.
This is cool, because many applications in Telegram are the work of one creator, who has to understand everything at once, and such a tip as a demo application will help him.
The STON.fi SDK is already the most canonical and popular solution for integrating DEX functionality on TON, and has been used by many apps, such as Blum for Memepad automation, TapSwap and HotWallet for swap functionality integration, and many other apps.
STON.fi is the largest DEX on the $TON blockchain and is actively working on improving the current DEX functionality and developing new solutions. Currently in beta is the #Omniston protocol, which exists to provide the best rate among all DEXs and resolvers with zero slippage.
The demo application code can be found on Github:
