Catchain 2.0 activation is underway

TON validators are voting to fully activate Catchain 2.0, a consensus upgrade that brings sub-second finality to the network.

The first phase has been live since April 2. Today, at 14:00 UTC, the final vote started to cut block times to 400 ms across the entire network.

To activate the upgrade, validators vote on-chain. The proposal needs support from at least 75% of validators (by stake weight) across two validation rounds, roughly 36 hours.

Blockchain Fee Reduction

The TON Core team has prepared a blockchain update to reduce fees by 6x, in line with Pavel Durov’s MTONGA plan.

This update includes:

1) Performance improvements

The previous Sub-Second update improved not only operation speed but also overall blockchain performance, making a fee reduction possible. Since then, additional optimizations and performance improvements have also been implemented, including a new mempool based on a persistent Cartesian tree.

2) Fixes

In addition to performance improvements, this update will include fixes for issues identified on mainnet after the Sub-Second release. In particular, it addresses loss of synchronization on some liteservers and rare block rate instability.

Planned Schedule:

April 28, 2026 12:00 UTC — Validator software update.
April 30, 2026 13:00 UTC — Vote to lower gas prices in the blockchain configuration.

Lower fees are important for the next stages of the MTONGA plan. Since fees do not constitute a significant portion of validator rewards, validator rewards are expected to decrease by less than 0.4%.

Mainnet validator operators are asked to be prepared to update their software on 28 April and to participate in the vote on 30 April.

Voting by validators on reducing network fees has begun

Introducing Acton — a new, modern toolchain for developing smart contracts on TON

Acton covers the full development lifecycle: project creation, testing, debugging, dApp integration, deployment, and verification.

CLI-first by design, it works naturally for both developers and AI agents.

1. One toolchain, not a bunch of utilities
Create, build, test, lint, format, deploy, and verify TON contracts in a single coherent environment around Tolk.

2. A tighter build-test-debug loop
Write tests directly in Tolk programming language, run them fast, debug failed transactions, and inspect what actually happened on-chain.

3. Security built in
Coverage, fuzzing, mutation testing, gas profiling, and CI help catch regressions early.

4. A native debugger
Step in, step over, step out, watch variables, and inspect the call stack. A smooth Web2-style developer experience, now inside a blockchain language.

5. Friendly for AI agents
A modern CLI tool that becomes an agent's runtime, with skills and manuals bundled.

6. IDE integtation
Use it with VS Code, JetBrains, Cursor, Zed, and other LSP‑based editors.

🪙 Toncoin Name Change — Community Vote

TON has changed substantially in recent months. Telegram is taking on a leading role in the network and is becoming its largest validator. The chain itself is now 10× faster with fees down 6×. Gram was the name the network's founders gave the token in the original TON White Paper, and it's never left the codebase.

That is why Telegram is proposing to rename the native token from Toncoin to Gram, a fitting moment to bring it forward.

The blockchain stays TON / The Open Network, only the token's name and ticker change. Balances, addresses, contracts, NFTs, staking, DeFi, all unchanged. No swap, bridge, claim, or migration. No action required.

⚠️ Any site, bot, or link asking you to "claim GRAM" or "migrate TON" is a scam.

Native Token Rename: Toncoin (TON) to Gram (GRAM)

The community vote on TON Vote has concluded. With 81.22% voting in favor, the native token of The Open Network is being renamed from Toncoin to Gram, with the ticker changing from TON to GRAM.

The change takes effect at 12:00 UTC on June 15, 2026. The blockchain itself stays The Open Network. Only the token's name, ticker, and logo change.

There is no swap, bridge, claim, or migration. No action is required from users. Balances, addresses, contracts, NFTs, staking, and DeFi positions all stay exactly as they are.

Voting opened on June 1, 2026 and closed on June 8, 2026.

All ecosystem projects, including exchanges, are expected to make the coordinated update at 12:00 PM UTC on June 15, 2026.

By June 22, 2026, full consistency is expected across all projects.
