In the upcoming version of Tact, we've introduced over 100 updates, including new features, dozens of bug fixes, and more than 20 optimizations that improve gas consumption. I want to highlight these optimizations because, until now, the most common reason for not using Tact has been its inefficiency.

For this release, we benchmarked our optimizations using the most common smart contract on TON—the Jetton. We compared our standard implementation against the reference FunC version, which is currently the most widely used. I'm happy to say that we’ve actually outperformed it!

On average, a Jetton compiled with this upcoming Tact version consumes just 95% of the gas used by the reference FunC implementation. This isn’t a cherry-picked result—these optimizations apply universally to all smart contracts, impacting them in almost the same way. Essentially, Tact is now on par with FunC in terms of gas efficiency—or even surpasses it in many cases—all while offering a much higher level of abstraction, enabling developers to build scalable, maintainable, and extensible projects with ease.

And this is just the beginning. We have a lot more to share in the coming months.
