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.

One of Acton’s key features is its advanced support for developing TON smart contracts using AI.

Hey everyone 👋

I just published a small package I've been working on - ton-better-auth. It's a Better Auth plugin that lets users sign in with their TON wallet using TON Connect.
The idea came from needing this for a project and not finding a clean solution. It handles the ton_proof verification on the backend - replay protection, signature validation, state-init parsing for different wallet versions, all that stuff.
Basic setup looks like this:

npm install ton-better-auth

import { betterAuth } from "better-auth";
import { tonConnect } from "ton-better-auth";

export const auth = betterAuth({
  plugins: [
    tonConnect({ allowedDomains: ["your-app.com"] }),
  ],
});

Works with @tonconnect/ui-react on the frontend and supports multi-wallet linking.

I also made AI skills for it:

npx skills add mhbdev/ton-better-auth

Let me know if you run into any issues or have feedback. Always happy to improve it.

Hi, can anyone share projects building agent economies on TON? I'm interested in A2A solutions. I know the marketplace ctlx.cc that took part in a hackathon, but so far it looks like an Agent-to-Human solution.

A quick update on the topic of the channel: in the major update to dTON’s liteservers, we’ve added MCP.

You can now type Add dton.io/mcp in Claude / Codex, log in via Telegram, and the agent will be able to work with liteservers itself: view balance, rates, keys, select an SDK for Go/Python/Node, check the liteserver, and view analytics on RPS, methods and duration.

Our LiteServer features:

• Pay as you go, $0.02 per liteserver request
• Detailed Analytics: RPS, methods, recent requests, durations.
• Custom Overlay: fast sync and external messages distribution
• 6 geo zones: one node catches block - all nodes have it
• LiteServer Boost: unlimited RPS bursts
• Archive LiteServer: 100% history

We won the TON AI Agent Hackathon and turned the project into a live marketplace — ctlx.cc.

You deploy your agent, it earns per call in TON / USDT. Payments and escrow are handled for you. There's a skill that rolls out your agent (or product) onto the site in a few minutes. Or you can run agents/products on our machine using @ctlx_seller_bot

Doesn't have to be an agent. We sell subscriptions and access too — Claude Code, ChatGPT, and the like. If you've ever asked where to buy these without a card, that's the whole point: pay in TON, no card, no KYC. Anything with digital delivery fits.

Also: we expose an MCP. Everything on the site is callable by your agents too — if they can pay in TON, they can buy. Agent-to-agent commerce, already in prod.
