Sub-Second mainnet activation starts
The public bug bounty contest for the TON Sub-Second update has been completed.
We thank all participants for their work and valuable feedback. The corresponding changes have already been applied to the codebase. No major consensus changes were required.
The final contest results and reward distribution will be announced later.
This contest was the final stage of testing before mainnet activation. Prior to that, the update had already passed internal testing by TON Core and extended testing in testnet.
We are now starting the activation of the Sub-Second update in TON mainnet.
For additional reliability, activation will be performed in 3 stages:
Update plan:
March 31 (today): Upgrade validator nodes to the version supporting the latest consensus changes.
April 2: Vote to activate the new consensus on the basechain and enable a moderate block rate increase.
April 7: Vote to fully activate fast consensus on both the basechain and masterchain and then upgrade validator nodes.
The Sub-Second update is a major protocol upgrade comprising a substantial number of changes.
Despite comprehensive testing, validators are advised to maintain heightened operational readiness during the next two weeks, from March 31 to April 12.
The TON Core team will remain available throughout the deployment and is prepared to respond promptly to any situations.

Historically, bot-to-bot interaction was restricted on Telegram to prevent infinite message loops.
Starting today, in specific contexts, Bot-to-Bot communication is allowed โ unlocking complex agentic flows and AI-powered use cases.
Out of the box, this feature will work in groups and via business mode. To start using it, simply enable the Bot-to-Bot Communication Mode for your bot via @BotFather.
You can reference the full documentation here.

Mainnet validators
Tomorrow, April 8, at 14:00 UTC, we ask validators to set aside time to vote on the following proposal:
โ Vote to change Config Parameter 30, to activate Catchain 2.0 in both masterchain and basechain with block production rate of 400ms.
In addition to improving network performance from a UX speed perspective, this change is also expected, based on the current network configuration, to increase total validator rewards. However, the final validation APY cannot be determined in advance, as it depends on the dynamic relationship between the total staked amount and the reward pool.

Voting is now live on mainnet for a change to config parameter 30 and the activation of Catchain 2.0, a new sub-second consensus with ~400ms block-time.
This is a fundamental change to our blockchain, allowing validators to communicate internally with each other using QUIC protocol.
There is a website where you can track the validator voting progress in real time:
https://vote.lagus.cooking/
Fingers crossed.

New for TON devs: Deep Smart Contract Audit Skill
A new audit skill for TON smart contracts is now live โ powered by TON Symbolic Analyzer (TSA) and combining LLMs with formal methods.
What is TSA?
A symbolic execution engine that simulates contract behavior across many possible states to uncover nonโobvious bugs.
What the skill does:
โข Explores real execution paths
โข Analyzes smart contract code at the bytecode level
โข Detects critical issues:
โ Unauthorized fund withdrawal scenarios
โ Incorrect handling of bounced messages
โ Replay attack vulnerabilities
โข Generates test cases
โข TSA enable deep analysis for higher security coverage.
โข Produces a structured audit report
โ๏ธ It is free and powerful smart contract audit skill for all TON developers!
More details:
๐ https://tonsec.dev/smart-contract-audit-agent
Includes a case study showing how it reproduced a real DEX vulnerability.

We're closing GraphQL endpoint at Jun 1.
We have to admit that, despite our best efforts to preserve the ecosystem, times have changed and our team needs to move on to other areas and opportunities.
If you use the GraphQL or Assets API endpoints, please find another data provider and switch to them by 1 June. The @dassets_bot portfolio will also cease to function on 1 June.
As for providing access to Liteservers, we will continue to provide access and no changes are expected for Liteservers at @dtontech_bot.
It has been an honour for our team to work on TON over the past 5 years. It has been a very interesting and enjoyable time. We have met unique and legendary individuals, and have come a long way. But it is time to move on and build our own unicorn.

How MCP enables on-chain actions for agents on TON
We publicly announced Agentic Wallets on TON โ an open, self-custodial standard that lets agents manage assets through dedicated wallets. But just having a wallet isnโt enough. For an agent to use TON, it needs to be able to find and connect tools for interacting with the blockchain.
Thatโs why we built mcp.ton.org โ a simple entry point for connecting AI agents to TON. MCP gives agents access to tools for working with the blockchain, while skills provide ready-to-use instructions. A user copies a single command, and the agent gets a ready way to work with the blockchain. All skills are open and available in the ton-org/skills.
Now developers have a ready-to-use execution layer for agents on TON. After connecting MCP and installing skills, an agent can check balances, send transactions, swap tokens, work with NFTs and execute more advanced scenarios like buying xStocks or managing Agentic Wallets. All actions are built from reusable primitives and executed through MCP, which allows developers to move directly to building agent logic.
Connect MCP and give your agent access to actions on TON

๐ฆ Guest Mode and Agentic Flows
โข Introduced guest mode, allowing bots to easily participate in any chat without joining it.
โข Users can summon up to 3 guest bots per message โ unlocking complex agentic flows in any chat. Guest bots receive only relevant messages and can inspect caller context or send replies.
โข Bots can now message each other by username if they enable bot-to-bot communication.
โข Account automation via Business Bots no longer requires a Premium subscription.
โข Business Bots can now interact with other bots on behalf of the user.
๐ก Chat Management
โข Admin bots can now remove individual message reactions, clear all recent reactions from a user or restrict them from issuing more.
โข The list of chat admins can now optionally return bot administrators.
๐ถ Live Photos
โข Introduced support for live photos โ images enhanced with short built-in motion and sound.
โข Bots can now detect, download and send live photos to any chat, including as paid media.
๐ Polls
โข Bots can now detect and attach media in both polls and individual poll options.
โข Polls can now be limited to existing chat members or voters from specific countries.
โ General
โข Users can now set a granular access whitelist for their bot via @BotFather, while Manager Bots can set one via the API.
โข Bots can now fetch recent messages from the channel pinned to a user's profile.

๐ช Toncoin Name Change โ 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 10ร faster with fees down 6ร. 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.
โ ๏ธ Any site, bot, or link asking you to "claim GRAM" or "migrate TON" is a scam.
How the vote works
Runs for one week on TON Vote, an established open DAO platform on TON โช๏ธ Voting power is weighted by TON balances
