MuTON
Open source mutation testing tool built for TON blockchain languages (FunC, Tolk, and Tact) using Tree-sitter for AST-aw
Our Take
MuTON is a mutation testing tool for TON blockchain developers working in FunC, Tolk, or Tact, and honestly any team shipping serious code in this ecosystem should care about test quality — this is built with Tree-sitter so it understands the actual AST rather than just mindlessly mutating syntax, which means your test suite actually gets stress-tested against real code breakdowns. It’s open source, free, and the kind of infrastructure tool that makes a blockchain platform feel legit even if most people won’t ever hear its name. If you’re building on TON and your tests feel too easy, this is probably the move.
