🫧 Tolk v1.3: moving toward a general-purpose language After the previous post, this release may feel less surprising — but still a bit unusual. The reason is simple: Tolk is no longer evolving only as a contract language. It is becoming a foundation for the toolchain I described earlier. This release focuses on features beyond contracts — introducing general-purpose capabilities needed for libraries and frameworks. ✅ Notable changes in Tolk v1.3: 1. Type array<T> — dynamically sized arrays backed by TVM tuples. 2. Type unknown — a TVM primitive with unknown contents. 3. Type lisp_list<T> — nested two-element tuples (FunC-style). 4. Type string — text chunks backed by snaked cells, with StringBuilder for concatenation. 5. Compile-time string methods: "str".crc32(), "str".sha256(), etc. 6. Null coalescing operator — ?? like in TypeScript. 7. Import path mappings — import "@third_party/utils". 8. Compile-time reflection via @stdlib/reflection. 9. Custom serializers now support structures and generics. 10. The compiler now reports multiple errors at once. 11. Focused on stability — fixed dozens of minor issues found by LLM fuzzing. 12. Extensive internal refactoring towards being stateless and multi-threaded. PR on GitHub with detailed info. ✔ Arrays: redesigned tuples Working with TVM tuples has been fully redesigned. There is now array<T> — a dynamically sized container:

// array<int>
var numbers = [1, 2, 3];

// array<Point?>
var optPoints = [
    Point { x: 10, y: 20 },
    Point { x: 30, y: 40 },
    null,
];

- methods push, get(idx), etc. - any T, including sub-arrays like array<array<int>> - automatically serialized into snake cells - max size: 255 (TVM limitation) ✔ The `unknown` type Raw TVM tuple exists, but it's no longer built-in. It's just an array... of something unknown:

type tuple = array<unknown>

The unknown gives access to the untyped TVM stack, fully integrated into the type system. ✔ The `string` type TVM has no strings — only binary slices. Strings were always just a convention over binary data. Now Tolk has strings built-in.

// string
val str = "hello";

- strings are cells (not slices) - long strings are snake cells under the hood - methods calculateLength, equalTo, etc. - on-chain/off-chain encoding for jettons and NFTs to comply with TEPs StringBuilder encapsulates cell manipulation:

StringBuilder.create()  
    .append(content.commonContent)  
    .append(individualNftContent)  
    .build()

By the way, compile-time functions now look cleaner: "str".crc32() and so on. ✔ Import path mappings The import statement now accepts @aliases:

import "@common/jettons"
import "@third_party/math-lib"

This is similar to widely used path mappings in TypeScript. ✔ Compile-time reflection Many additions in v1.3 make sense not for contracts, but for frameworks. For example, take a look at one of reflect features:

fun log(msg: string, loc: SourceLocation = reflect.sourceLocation()) {
     debug.print(loc.lineNo);
}

fun demo() {
     log("a");    // prints K — current line no
     log("b");    // prints K+1
}

Why is this useful? It allows errors to point to the original call site — for example, expect(...) in tests — by carrying source location at compile time. ⚙️ A huge portion of internal refactoring A lot of work has been done inside the compiler core, peephole optimizations, and memory management. Final result: tolk compiler is now thread-safe and re-invokable within a single process. It will be embedded into an external toolchain written in Rust, communicating via FFI. ... And more Dozens of independent improvements. Combined, they cover the requirements not only for contracts, but for abstract libraries and the upcoming toolchain. Feel free to check the description on GitHub. 🌳 And one more thing! Wallet-v5, compiled with Tolk v1.3, reduces gas usage by 30% compared to FunC. As of Tolk v1.0, the savings were "only" 20%. Take a look at new benchmarks.

💎 Tolk v1.3 is live — expanding scope beyond smart contracts Tolk is evolving into a general-purpose language, enabling the next layer of TON tooling: • Library development • Framework support • Developer tooling infrastructure This release lays groundwork for a more complete development stack on TON. TON Core team is improving developer experience with focus on onboarding, usability, and tooling consistency. More technical updates will follow. 👉 Start building on TON TON Community | TON Hubs |X | YouTube | LinkedIn | TON.org

💎 WalletConnect now supports TON. WalletConnect's global network, which connects 500M+ users across 700+ wallets and facilitated more than $400B in transaction volume in 2025, now has access to TON's expanding stablecoin economy and DeFi ecosystem. To enable this, TON Connect protocol has been extended to support WalletConnect as a transport layer, allowing TON dApps to interact with multichain wallets without building wallet connection support from scratch. 💎 What this means for the ecosystem:

• Wallets with WalletConnect can now support TON with minimal integration effort. • Institutions gain access to TON's DeFi and liquidity layer. • Apps can attract non-TON native audiences.

🏅 Fireblocks and SafePal are among the first to integrate TON through WalletConnect. Through Fireblocks' network of 2,400+ institutional clients, organizations can now tap into TON-based DeFi, including liquidity pools and liquid staking, and incorporate TON into existing treasury workflows. With institutional capital flowing in, TON's DeFi platforms like STON.fi, DeDust, Tonstakers, Affluent, Storm, and TONCO stand to benefit from deeper liquidity, which in turn means better opportunities for everyday crypto users. 👉 Read more: https://walletconnect.com/blog/walletconnect-adds-support-for-ton-expanding-stablecoin-payments-across-a-fast-growing-ecosystem TON Community | TON Builders | TON Hubs | X | YouTube | LinkedIn | TON.org

Sub-second finality: how to adapt your project TON is rolling out Catchain 2.0, a consensus upgrade targeting sub-second block finality on mainnet in early April 2026. What's changing: – Block interval: ~2.5s → 200–400ms – Finalization lag: ~10s → ~1s – Throughput: up to ~5 blocks/sec But a faster chain alone won't help users if apps still rely on old API. We've published a step-by-step adoption guide covering: 🔹 Wallets & dApps: switch to TON Center Streaming API v2. Handle all four statuses: pending → confirmed → finalized → trace_invalidated. 🔹 Self-hosted nodes & liteservers: update to the latest release with Catchain 2.0 support before mainnet activation. 🔹 Indexers: prepare for up to 10x more blocks/sec. Connect to testnet and verify no lag accumulates over 30+ minutes. Testnet already runs at sub-second speed. Test there now. MyTonWallet and tonscan.org already use Streaming API and have nearly halved their reaction time, even before the mainnet upgrade. 📖 Full guide: How to adopt sub-second finality Start adapting today. If your app isn't ready, users won't notice any improvement.

🪙 Report: Telegram as the default AI interface IdentityHub published a report exploring Telegram as an emerging interface for AI agents. Instead of building standalone dashboards, developers can run workflows, automation and agents directly inside chat. For builders on TON, this model aligns with bots, Mini Apps and agent-based services deployed where users already interact. 😏 Read the report TON Community | TON Coin | TON Hubs |X | YouTube | LinkedIn | TON.org

💎 Why TON Pay? Payments shouldn’t require every builder to implement the same infrastructure. In Telegram apps, that often meant creating wallets, checkout flows and settlement logic from scratch. TON Pay simplifies the integration 🚀 One SDK for Mini Apps, bots, and backend services. One-time payments, recurring payments, and subscriptions. Non-custodial, with funds remaining under user control. Focus on the product, not the payment stack. ⛏️ TON Community | TON Coin | TON Hubs |X | YouTube | LinkedIn TON.org

Unfortunately, due to the Middle East conflict and safety conditions in the UAE area, we have made the decision to cancel Gateway Dubai, originally scheduled for May 1 and 2, 2026. This was a difficult call, but the safety and well-being of our community always comes first. If you purchased a ticket to Gateway through Luma, Moongate or Tribute, or booked hotel reservations through promocode, you will receive a refund within the next 14 days. For further questions, please contact: gateway@ton.org. We are currently examining different formats to produce a Gateway event before the end of this year. An announcement will be forthcoming in the near future. We look forward to seeing you soon.
