Telegram CEO Pavel Durov unveiled Acton, a unified development toolchain for TON that promises to make smart contract building 10x faster than the old fragmented stack. The launch follows Telegram's move on May 4, when it staked 2.2 million TON tokens to claim the largest validator slot from the TON Foundation, part of Durov's 'Make TON Great Again' roadmap. Acton is built around Tolk, TON's newer smart contract language, and handles writing, testing, deployment, and on-chain verification in a single environment.
What Acton does
Acton tests run about 50 times faster than before. It works with popular code editors, includes built-in debugging and testing, and allows local blockchain simulation. Durov designed it for AI-driven development — the toolchain comes with dedicated guides for AI coding agents and supports tools like Codex and Claude. The idea is simple: make TON the easiest chain to build on, especially for mini-apps.
The validator play
Telegram's validator stake isn't small. By claiming the largest slot, the company tightens its control over TON's validator set. Analysts flagged centralization risks even as they acknowledged the protocol improvements. Toncoin (TON) rallied more than 100% after the validator news but later retraced. Durov's roadmap has already cut transaction fees sixfold and rolled out a faster consensus mechanism.
Catchain 2.0 and speed
That faster consensus is Catchain 2.0, an upgrade that pushed network finality below one second in April 2026. TON now finalizes transactions in 0.6 seconds — Durov calls it the fastest L1. Telegram's user base of nearly one billion gives TON a distribution advantage no rival chain can match. But speed and scale won't matter if developers don't show up.
Acton's mainnet deployments in the coming weeks are the real test. They'll signal whether TON can challenge Solana and Ethereum in mini-app commerce. For now, Durov has the tools and the validator power. The question is whether the ecosystem will follow.
