Meet Tolk 1.0 — a new programming language for creating bulletproof smart contracts on TON

Tolk combines expressiveness, convenience, and low-level power, inheriting security, economy, and efficiency from FunC.

What makes Tolk special:

— Simple and readable syntax: as close as possible to familiar modern languages such as TypeScript and Kotlin.

— New language features for the TON asynchronous actor model: auto-serialized structures, pattern matching, smart casts, and convenient message management.

— Advanced type system: generics, null safety, type aliases, union types — everything you need to write safe and flexible code.

— Maximum efficiency: smart contracts on Tolk are cheaper than smart contracts on FunC — benchmarks show up to 50% gas savings thanks to compiler optimizations and unique “lazy” loading.

— Deep control: ability to go down to the bits and manipulate the stack when necessary.

— Redesigned standard library. Convenient language versioning and delivery system.

Tools and resources:

— Basic documentation for learning Tolk from scratch.

— Reference smart contracts with benchmark results: Jettons, NFT, Wallet v5, Telegram Gift and others.

— Migration guide from FunC and automatic converter.

— Support in IntelliJ IDEA, VSCode and Language Server.

— Integration with Blueprint and verifier.ton.org.

— The first production-ready contract on Tolk from TON Core — a Payment Channel.
