The final patch release of this v1.6 series is upon us, and it brings a significant tooling improvement, amongst other things. Meet the official Tact formatter — a new tool that ensures consistent code style across your Tact projects. It ships with Tact v1.6.6, and you can run it in your projects via
npx tact-fmt or by invoking a format command in your editor. You'd need to install the Tact's language server or the VSCode extension for that — see the tact-language-server repo for details.The v1.6.* series of patches has been a journey of refinement and polish, setting the stage for what's coming next. As we close this chapter, we're already working hard on exciting new features for the future.
For now, let's explore the Tact v1.6.6 release:
🧰 Standard library additions and changes
• Added compute phase exit code constants reserved by the Tact compiler, such as
TactExitCodeNullReferenceException (128) and many others.• Added the SignedBundle struct and the corresponding verifySignature method.
• Added
sendRawMessage and sendRawMessageReturnForwardFee functions as replacements for their deprecated counterparts.• Optimized the
sha256() function to about ~270 less gas used per call and added the keccak256() function that works with arbitrarily long slices.🛠 Bug fixes
There were a lot of those. Remember that last time we started fuzzing the compiler with LLMs to root out bugs? Well, we found many bugs that way and fixed even more — many error messages got way more informative and useful. Some bug fixes allowed for seemingly unrelated UX improvements too.
One nice example of a second-order fix would be that the
require() function now supports constants as its second parameter. You no longer need to provide identical string literals everywhere — define a string constant somewhere and reuse it!See the full release notes for a long list of bugs squished and error messages improved.
✍️ Documentation updates
• Added a "Learn Tact in Y minutes" page, which gives a whirlwind code-first tour of the Tact language.
• Any AI vibe coders out there? The docs now generate
llms.txt, llms-full.txt and llms-small.txt files for you to use with your AIs. The small version is particularly interesting as it fits in the 200k context.• The "gas best practices" page got updated with new recommendations, such as specialized math functions or the
BasechainAddress struct and related functions.• Lots of examples fixed, with more fixes to arrive as we speak.
🧳 Formatter!
You can run it via
npx tact-fmt in your projects — it supports checking the formatting via the --check flag, applying fixes via the --write flag, and can check both individual files and directories of files.Furthermore, it also ships with our official language server and VSCode extensions. See the tact-language-server's README.md for installation details.

🫧 Tolk v0.11: type aliases, union types, and pattern matching
This update might confuse you at first. You may wonder: "Why do we need this? How will it be useful?". But in the end, you'll see how everything comes together bringing seamless and generalized message handling.
✅ Notable changes in Tolk v0.11:
1. Type aliases
2. Union types
3. Pattern matching for types
4. Operators
5. Pattern matching for expressions
6. Semicolon for the last statement in a block can be omitted
PR on GitHub with detailed info.
✔ Type aliases
Tolk now supports type aliases, similar to TypeScript and Rust.
An alias creates a new name for an existing type but remains interchangeable with it. No performance overhead — a compile-time feature.
✔ Union types `T1 | T2 | ...`
They now allow a variable to hold multiple possible types.
Nullable types
At the TVM level, union types work as tagged unions — similar to Rust enums but more flexible.
✔ Pattern matching
The only way to work with union types is matching them:
Matching is based on smart casts — inside each branch, the variable is automatically narrowed to the matched type.
It can also be used as an expression:
So, `match` + smart casts are our way for union types. You may notice that it's close to enums in Rust. But we don't have enum. Union types are more general and powerful.
✔ `match` for expressions
As you see, match also works for constant expressions, similar to switch in other languages.
✔ Union types and TL/B `Either`
Look how clean this is:
No need to manually handle bits from the slice — it's naturally expressed in the type system!
✔ Union types and TL/B constructors
Moreover — handling incoming messages is beautifully expressed with union types.
✔ Union types and future structures
The ultimate goal? You'll describe each incoming message as a struct, create a union type for them, parse a slice, and just match over variants:
🌳 So, union types (that perfectly work with tensors) will seamlessly work with structures. With union types, you will declare both Either and different kinds of messages. Combined with intN and other types, they will allow to express (almost) any practical TL/B construction. They are not limited to message routing — in other words, message routing does not differ from handling any field, any storage, or any cell in general.

🎉 Tact v1.6.5 is released!
Back with another round of refinements! While we're working on many exciting things in the background, we're committed to fixing every bug that the community might discover so that Tact can provide a flawless developer experience.
Furthermore, we now actively employ AI and large language model (LLM) fuzzing techniques, such as documentation-driven approaches where LLMs are given only the Tact language documentation and access to the compiler. Then, LLM agents generate potentially problematic code snippets, compile them, and analyze results. They further iterate and provide new, interesting bug reports — resolving those makes both Tact compiler and Tact documentation better at the same time!
Check out this awesome article from one of the team members to learn more: Documentation-Driven Compiler Fuzzing with Large Language Models.
And now, let's see what's new in Tact v1.6.5, starting with the most prominent part of this patch release:
🛠 Bug fixes
• Ternary operator
• New parser now properly handles the code that wasn't completed at the end of the file
• The error for assembly functions and the
• Now, when you call the
• Improper whitespace between the operator and the equals sign is no longer allowed

LLMs are great, but we value our community no less. It's great being around a bunch of talented, passionate, and bright engineers who make a future of safe and scalable ⚡️ Tact smart contracts on TON possible for everyone. Thank you for everything you do and for the feedback you give!
A special shoutout goes to the RSquad team @rsquadlife for their early adoption of Tact features, thoughtful suggestions, and bug reports. If punk were code, they'd be its maintainers 🤘

Struct.fromSlice(), Message.fromSlice(), and similar functions now work properly if the slice has been parsed entirely and the last field of the struct had the serialization annotation as remaining• The wildcard symbol
_ is prohibited for struct and message struct fields, function names, contract, and trait names• The contract's state is now properly saved on early
return statements in the receiver functions🧳 Miscellaneous improvements
• Whenever you access
context().sender, it now calls the sender() function instead to optimize the gas usage• The
internalExternalReceiversOutsideMethodsMap option and its respective receiver order optimization were reworked to ensure compatibility with explorers and user wallets• The
SendPayGasSeparately constant was deprecated in favor of SendPayFwdFeesSeparately — they're functionally identical, but the latter better expresses the intent and action that this optional flag makes when sending messages• The
Stoppable trait now throws the exit code 133 instead of the exit code generated by the require() function from the "Contract stopped" message📜 See the full release notes for Tact v1.6.5

🫧 Tolk v0.10: preparing for serialization — intN, bytesN, coins
This update lays the foundation of future auto-packing to/from cells by solving one critical question:
How should fields be serialized?
✅ Notable changes in Tolk v0.10:
1. Fixed-size integer types:
2. Type
3. Types
4. Replace
5. Trailing comma support
PR on GitHub with detailed info.
❓ Fixed-size integers? In TVM? What?
Imagine Tolk already has structures, and we define an incoming message:
A client sends this message following the TL/B schema:
But how do we tell the compiler that counter_id is int32 and inc_by is int64? This information is missing in the struct definition.
✖ Rejected approaches: why they fail
Several syntax ideas were considered:
Each of these quickly breaks down when handling more complex cases.
For example, how would we handle TL-B
And what about TL/B
With every new case, the syntax becomes more complex, ambiguous, and error-prone.
✔ The solution: `int32` as a first-class type
No annotations. No confusing
This scales perfectly:
These are distinct types. A variable can be
This makes serialization predictable, structured, and error-free.
✔ What about overflow?
A reasonable question: what happens if a value exceeds the limit?
Answer: no runtime overflow or clamping! It's just int at TVM.
* arithmetic works normally – v becomes 256
* no extra gas cost – no runtime bounds checks
* overflow will only happen at serialization
✔ Why is this the best approach?
Think of smart contracts as a black box:
- inputs are encoded (int32, uint64, etc.)
- inside the contract, arithmetic uses full 257-bit precision
- outputs are serialized again — overflow happens only at this stage
This is similar to how mulDivFloor(x,y,z) uses 513-bit precision internally. Your contract keeps precision internally and only enforces constraints at the border with an outside world.
🌳 Tolk will follow a type-based philosophy
This post covered the foundation of automatic serialization. The right way is to have a rich type system. Having nested types, having generics, having aliases — will allow to describe every practical TL/B case, but at a language level.
In v0.10, we introduce
How will

int32, uint64, etc.2. Type
coins and function ton("0.05")3. Types
bytesN and bitsN (backed by slices at TVM)4. Replace
"..."c postfixes with stringCrc32("...") functions5. Trailing comma support
PR on GitHub with detailed info.
❓ Fixed-size integers? In TVM? What?
Imagine Tolk already has structures, and we define an incoming message:
A client sends this message following the TL/B schema:
counterIncrement
counter_id:int32
inc_by:int64
= CounterIncrement;
But how do we tell the compiler that counter_id is int32 and inc_by is int64? This information is missing in the struct definition.
✖ Rejected approaches: why they fail
Several syntax ideas were considered:
Each of these quickly breaks down when handling more complex cases.
For example, how would we handle TL-B
Maybe int32? Would we write:And what about TL/B
Both (Maybe int32) int64?With every new case, the syntax becomes more complex, ambiguous, and error-prone.
✔ The solution: `int32` as a first-class type
No annotations. No confusing
as syntax. No ambiguity.This scales perfectly:
These are distinct types. A variable can be
int32 and similar:This makes serialization predictable, structured, and error-free.
✔ What about overflow?
A reasonable question: what happens if a value exceeds the limit?
Answer: no runtime overflow or clamping! It's just int at TVM.
* arithmetic works normally – v becomes 256
* no extra gas cost – no runtime bounds checks
* overflow will only happen at serialization
✔ Why is this the best approach?
Think of smart contracts as a black box:
- inputs are encoded (int32, uint64, etc.)
- inside the contract, arithmetic uses full 257-bit precision
- outputs are serialized again — overflow happens only at this stage
This is similar to how mulDivFloor(x,y,z) uses 513-bit precision internally. Your contract keeps precision internally and only enforces constraints at the border with an outside world.
🌳 Tolk will follow a type-based philosophy
This post covered the foundation of automatic serialization. The right way is to have a rich type system. Having nested types, having generics, having aliases — will allow to describe every practical TL/B case, but at a language level.
In v0.10, we introduce
intN (fixed integers), bytesN (definite slices), coins (variadic integers), and some more additions. Read the details in the PR.How will
Either L R and even more complex TL/B structures be expressed? Stay tuned for the next update...

✈️ The First AI Developer Community in TON is Here! 🚀
A new developer community TON AI Narrative has been launched in TON! This is a place where we explore the synergy of AI + Web3 + Telegram and build the future of AI agents in TON.
💡What’s in TON AI Narrative?
📌 AI tutorials for TON
📌 Technologies and tools for AI agents
📌 Events and challenges for developers
🔥 TON AI Plugin – The First Step Toward TON AI SDK
Our community has built the first AI tool for TON – TON AI Plugin in the ElizaOS framework.
The goal is simple: any developer should be able to create an AI agent on TON in just 15 minutes.
💡 AI agents can’t get bank accounts, but they can get crypto wallets.
Now, AI can hold and manage crypto, make transactions, and interact with smart contracts – unlocking.
Example:
💬 “I have $5000 and want to invest in DeFi”
👉 Agent builds the transaction for you, distributing funds across Dedust, Storm, Eva, and other DeFi protocols on TON. All you need to do is review and sign the transaction.
But this is just the beginning! TON AI Plugin is the first step toward a full TON AI SDK, which will provide tools for AI agent development, Web3 integration, and Telegram interaction.
🐞 Join the Bug Bounty – Test the TON AI Plugin!
We are looking for enthusiasts who want to explore AI’s potential in Web3 and help improve this tool.
💵 The top 3 bug reporters will receive a cash reward!

During the last year all dTON services were running on kubernetes cluster without HA build. Sometimes when we lost servers, we faced complex problems.
To improve the stability and availability of the service we developed high availability dTON cluster that will continue to work even if some of the servers are unavailable. Additionally, we've got setup complex monitoring and alerting system on services and data consistency.
Today we managed to switch all our services to HA cluster.
In our article we want to share our experience of HA cluster on top of bare-metal servers in three parts:
- dTON Kubernetes High Availability Transition
- dTON LiteServers High Availability Transition
- dTON GraphQL High Availability Transition
Second and third part will be posted exclusively on @dtontech with promo codes on dTON API usage.

For now, let's explore the Tact v1.6.6 release:
🧰 Standard library additions and changes
• Added compute phase exit code constants reserved by the Tact compiler, such as
TactExitCodeNullReferenceException (128) and many others.• Added the SignedBundle struct and the corresponding verifySignature method.
• Added
sendRawMessage and sendRawMessageReturnForwardFee functions as replacements for their deprecated counterparts.• Optimized the

require() function now supports constants as its second parameter. You no longer need to provide identical string literals everywhere — define a string constant somewhere and reuse it!See the full release notes for a long list of bugs squished and error messages improved.
✍️ Documentation updates
• Added a "Learn Tact in Y minutes" page, which gives a whirlwind code-first tour of the Tact language.
• Any AI vibe coders out there? The docs now generate
llms.txt, llms-full.txt and llms-small.txt files for you to use with your AIs. The small version is particularly interesting as it fits in the 200k context.• The "gas best practices" page got updated with new recommendations, such as specialized math functions or the
BasechainAddress struct and related functions.• Lots of examples fixed, with more fixes to arrive as we speak.
🧳 Formatter!

🎉 Tact v1.6.5 is released!
Back with another round of refinements! While we're working on many exciting things in the background, we're committed to fixing every bug that the community might discover so that Tact can provide a flawless developer experience.
Furthermore, we now actively employ AI and large language model (LLM) fuzzing techniques, such as documentation-driven approaches where LLMs are given only the Tact language documentation and access to the compiler. Then, LLM agents generate potentially problematic code snippets, compile them, and analyze results. They further iterate and provide new, interesting bug reports — resolving those makes both Tact compiler and Tact documentation better at the same time!
Check out this awesome article from one of the team members to learn more: Documentation-Driven Compiler Fuzzing with Large Language Models.
And now, let's see what's new in Tact v1.6.5, starting with the most prominent part of this patch release:
🛠 Bug fixes
• Ternary operator
• New parser now properly handles the code that wasn't completed at the end of the file
• The error for assembly functions and the
• Now, when you call the
• Improper whitespace between the operator and the equals sign is no longer allowed

Struct.fromSlice(), Message.fromSlice(), and similar functions now work properly if the slice has been parsed entirely and the last field of the struct had the serialization annotation as remaining• The wildcard symbol
_ is prohibited for struct and message struct fields, function names, contract, and trait names• The contract's state is now properly saved on early
return statements in the receiver functions🧳 Miscellaneous improvements
• Whenever you access
context().sender, it now calls the sender() function instead to optimize the gas usage• The
internalExternalReceiversOutsideMethodsMap option and its respective receiver order optimization were reworked to ensure compatibility with explorers and user wallets• The
SendPayGasSeparately constant was deprecated in favor of SendPayFwdFeesSeparately — they're functionally identical, but the latter better expresses the intent and action that this optional flag makes when sending messages• The
Stoppable trait now throws the exit code 133 instead of the exit code generated by the require() function from the "Contract stopped" message📜 See the full release notes for Tact v1.6.5
