The TON Foundation has launched Tolk, a new smart contract programming language poised to simplify development on The Open Network (TON) blockchain and lower costs for developers.

What is Tolk?

Tolk is designed to replace the existing FunC language as the primary development standard for TON. It is specifically tailored for TON's asynchronous actor model, aiming to make smart contract creation more accessible to newcomers while increasing efficiency for experienced developers building high-throughput applications.

Key Benefits of Tolk:

  • Simplified Syntax: Tolk boasts a cleaner and more modern syntax, making it easier to learn and use.
  • Cost Reduction: Contracts written in Tolk can potentially use up to 40% less gas than equivalent contracts in FunC, resulting in significant savings on execution fees.
  • Improved Scalability: Reduced gas consumption translates to improved scalability for applications built on TON.
  • Enhanced Developer Experience: Tolk comes with comprehensive tooling support, including migration paths for existing contracts and seamless integration with popular development environments.

Why Tolk Matters:

The introduction of Tolk is part of TON Foundation's wider strategy to foster ecosystem growth by enhancing the developer experience, aligning with modern programming practices, and boosting deployment efficiency. This could lead to faster adoption of TON across various sectors such as decentralized finance (DeFi), gaming, and social applications.

Key Takeaways:

  • TON has launched Tolk, a new smart contract language.
  • Tolk aims to simplify development and reduce gas costs.
  • The launch includes tooling and migration support.

Market Reaction:

Despite the positive news, TON's native token (TON) experienced a slight dip in price at the time of the announcement. Technical analysis indicated a volatile trading session with key support and resistance levels identified.
