Smart contracts for the TON blockchain

TON (The Open Network) isn't just another blockchain. It's an infrastructure designed from the ground up for mass Web3 adoption and tightly integrated with the Telegram ecosystem. This gives TON a unique advantage: the ability to launch decentralized services where their audience already exists, without the need for complex onboarding or external Web3 interfaces.

For startups, fintech teams, and digital products, TON is becoming a practical alternative to congested networks: it combines high transaction processing speed, scalability, and low fees. This is why the TON blockchain is now actively used for DeFi products, NFT platforms, gaming ecosystems, and the Telegram Mini App.

TON is particularly effective for products with high user traffic—games, marketplaces, social services, and payment solutions within Telegram.

Features of TON

• high throughput and fast transaction confirmation;
• low fees even with increasing load;
• a developed ecosystem of wallets and infrastructure tools;
• native integration with Telegram Mini App;
• active development of token, NFT, and DAO standards.

These features form the technological basis for scalable Web3 products aimed not only at the crypto audience, but also at the mass market.

Benefits of TON Development for Web3 Products

TON smart contract development enables the creation of products that seamlessly integrate into Telegram user scenarios and do not require clients to have in-depth technical knowledge of blockchain.

For business this means:

• lower entry threshold for users;
• fast time-to-market;
• the ability to scale without a sharp increase in infrastructure costs;
• stable operation under high load.

CryptonisLabs acts as a professional developer of the TON blockchain, building the solution architecture not for demo purposes, but for real production loads and long-term operation.

When TON is not the optimal choice

Despite TON's strengths and its tight integration with Telegram, the platform isn't suitable for all projects. During the architectural design phase, it's important to consider the ecosystem's limitations and the product's actual goals.

TON may not be the best choice if:

1. the product is aimed exclusively at the classic Web3 audience already working with Ethereum, Solana or EVM ecosystems;
2. the project requires full compatibility with EVM, existing smart contracts, or DeFi protocols from other networks;
3. the business model does not include integration with Telegram or the use of Mini App as a user interface;
4. requires complex cross-chain logic with infrastructure already deployed in other blockchains;
5. The team plans to use ready-made Web3 tools and templates focused exclusively on the EVM stack.

In such cases, alternative blockchain platforms may prove more suitable in terms of ecosystem, standards, and speed of integration.

That's why, before starting development, it's important to evaluate not only the benefits of TON, but also the platform's suitability for a specific business task, user scenario, and product scaling strategy.

Turnkey development of TON smart contracts

CryptonisLabs provides turnkey TON smart contract development, from logic design to mainnet deployment and ongoing support.

We close the full cycle:

• creation of a smart contract in TON for the business logic of the product;
• payment and financial smart contracts;
• gaming and NFT contracts;
• DAO and governance mechanics;
• custom on-chain scenarios.

The turnkey format means that you don't receive a separate contract, but a working architecture ready for scaling and integration.

Estimated cost of developing TON smart contracts

The cost of developing smart contracts in the TON network depends on the complexity of the business logic, the project architecture, the number of on-chain scenarios, and security requirements. Below are approximate ranges to help you estimate your initial budget.

The budgets provided are indicative and depend on the project architecture, security, audit and scalability requirements.

Development languages: Tact and FunC

Smart contracts on Tact

The Tact language is the core tool for modern TON development. Smart contract development in Tact is used in projects where the following are important:

● complex business logic;
● safety;
● convenience of further support;
● integration with Mini App and DeFi modules.

FunC

FunC is used for scenarios where maximum performance optimization and full control over low-level contract execution logic are required.

The choice between Tact and FunC is determined by the project architecture, performance requirements, scalability, and business logic features.

The CryptonisLabs team will help you conduct a technical assessment of your project and select the optimal TON development stack for your business objectives, launch timeline, and budget.

TON Smart Contract Architecture

We are designing a comprehensive smart contract architecture for TON that takes into account not only the technical implementation but also real-world business use cases. This approach enables the creation of scalable solutions ready for user growth and expanded functionality.

As part of the architecture, we implement:

• tokens and payment contracts for working with digital assets;
• DAO on TON and project governance modules;
• DeFi contracts for financial scenarios, including token staking, vesting, and liquidity pools;
• NFT on TON and game mechanics for digital collections and in-game economies;
• complex multi-contract workflows for interaction between multiple product components.

We design architecture taking into account:

• security of users' funds;
• scalability;
• secure update capabilities;
• integration with external services.

Testing and deployment of TON projects

Before launching on the TON mainnet, we conduct a comprehensive test of smart contracts to ensure the logic works correctly and the product is ready for real users.

As part of our preparation for production, we perform:

• local testing via Sandbox;
• deployment and debugging via TON CLI;
• testing work with Tonkeeper and Telegram Wallet;
• testing boundary scenarios and transaction logic.

This allows us to identify logical errors and potential vulnerabilities before the project goes live on mainnet, mitigating risks during scaling. After testing, we support the deployment and ensure the stable launch of the TON project.

Creation of Jetton tokens (TON)

CryptonisLabs creates Jetton tokens for various business models, from utility tokens to DeFi and GameFi economies.

Jetton is a token standard in the TON ecosystem, similar to ERC-20 in other networks, but optimized for the TON architecture.

What does the Jetton TON token issue involve?

• setting the volume of token issue (supply - fixed or dynamic);
• implementation of the logic for issuing and burning tokens (mint / burn);
• secure transfer of tokens between users (transfer);
• optimization of network fees and computing costs (gas);
• integration of tokens with TON wallets.

We provide turnkey Jetton token development, including economic modeling and technical implementation.

Integration with TON wallets

We ensure full compatibility of solutions with:

• Tonkeeper;
• Telegram Wallet;
• other clients of the TON ecosystem.

This ensures user convenience and correct transaction operation across all popular interfaces.

NFTs and GameFi on TON

TON is actively used to launch NFT platforms and gaming products aimed at the Telegram audience.

Development of NFT projects TON

We perform:

• NFT release on TON;
• creation of collections;
• development of game items;
• launch of NFT TON marketplaces;
• on-chain trading mechanics.

NFTs on TON are particularly effective for gaming and Telegram projects due to their low fees and fast user experience.

Telegram Mini App on TON and Web App Integration

We develop Telegram TON mini-apps that directly interact with smart contracts.

This includes:

• development of Telegram web applications for the TON network (Telegram Web App TON);
• integration of Telegram mini-applications with blockchain (Mini App Telegram blockchain integration);
• connection of the protocol for interaction with TON wallets (TON Connect);
• optimization of user scenarios and interfaces (UX optimization).

The user can perform on-chain transactions without leaving Telegram.

DeFi and DAO scenarios

TON is ideal for creating financial products and DAO platforms thanks to its high network speed, low fees, and user-friendly smart contract architecture. This allows for the launch of scalable DeFi services and governance mechanisms aimed at both crypto and Telegram users.

DeFi mechanics

We implement key financial scenarios, including:

• placement of tokens with accrual of rewards (staking and reward contracts);
• phased unlocking of tokens and asset blocking periods (vesting and lock periods);
• yield farming and liquidity stimulation (yield farming);
• liquidity pools for decentralized exchanges;
• custom economic models and financial logic of the project (custom tokenomics).

Within DAO scenarios, we complement DeFi mechanics with decentralized governance and decision automation tools, creating a sustainable financial infrastructure based on TON.

DAO on TON

We are developing DAO TON — decentralized project management systems that automate decision-making and reduce dependence on centralized processes.

As part of the DAO creation, we will implement:

• project management contracts (governance contracts);
• voting and quorum systems;
• project treasury management (DAO treasury management);
• Automatic execution of decisions in the blockchain (on-chain execution).

A DAO allows for the development of a transparent governance model, simplification of operational processes, and project scalability without increasing administrative burden.

Integrations with Telegram and TON Connect

Integrating TON projects with the Telegram ecosystem simplifies user onboarding and makes blockchain interaction as native and convenient as possible. We're building a connection between the Mini App, wallets, and smart contracts so that user interactions are fast and secure.

Telegram login and wallet connection

We implement:

• user authorization via Telegram (Telegram login);
• connecting TON wallets via the TON Connect protocol;
• secure confirmation of transactions within the application interface.

Mini App and interaction with smart contracts

Users can perform on-chain operations directly from the Telegram Mini App interface, without having to navigate to third-party websites or external wallets.

Audit and security of TON smart contracts

The TON project's security is built into the architecture design, not added after launch. Therefore, before publishing on the mainnet, we conduct a comprehensive review of smart contracts and component interaction logic.

In preparation for the launch, we are conducting:

• software code audit;
• testing economic vulnerabilities and tokenomics logic;
• checking access rights and management roles;
• preparing the architecture for scaling and load growth.

This approach reduces the risk of lost funds, errors in business logic, and problems as the user base grows.

An example of a TON project: Notcoin (Telegram Mini App)

Notcoin is one of the most well-known projects in the TON ecosystem, demonstrating how to scale a Web3 product through Telegram. Launched as a mini-app within Telegram, the project attracted tens of millions of users without a separate mobile app or complex onboarding.

How the solution works

The project is built on a combination of Telegram and the TON blockchain:

• mini-application inside Telegram for user interface (Telegram Mini App);
• TON smart contracts for token processing and accrual logic (smart contracts);
• native token of the TON standard (Jetton);
• connecting user wallets via TON Connect.

The user interacts with the application in Telegram, and all token transactions are carried out directly on the blockchain.

Business benefits of the model

This approach allowed the project to:

• quickly attract a mass audience to Telegram;
• reduce the entry barrier for users without experience in cryptocurrencies;
• automate the accrual and distribution of tokens;
• create a scalable economy without centralized transaction processing.

Why is this important for business?

This case demonstrates that TON enables the launch of products that:

1. scalable to millions of users;
2. work directly within Telegram;
3. use tokens as part of the business model;
4. do not require complex infrastructure at the start.
