Lessons on developing smart contracts on FunC for The Open Network(TON). The lessons are located in the appropriate folders in .md format, and a code is attached to each lesson. Our community - here. The lessons are first done in Russian here, and then I gradually translate them into English, if you want to help - the donation addresses are below.
