TON and Telegram Web3

TON blockchain development: contracts and apps for TON and Telegram

We build smart contracts in Tact and FunC, jetton and NFT logic, wallet connections and Telegram Mini Apps that use TON. Scope and price are agreed in writing before work begins.

  • Tact and FunC contracts
  • Jettons, NFTs and TON Connect
  • Telegram Mini App front ends

What we build on TON

TON is the network closely tied to Telegram, and its contract model is different from Solidity chains. We build:

  • Smart contracts in Tact or FunC.
  • Jetton tokens and NFT collections.
  • Staking, vesting and reward contracts.
  • Telegram Mini Apps with wallet sign-in through TON Connect.
  • Bots and backend services that watch contract events.

For the contract work in general, see smart contract development.

How TON contracts work

TON contracts are actors that communicate by sending asynchronous messages, so one action can span several transactions across several contracts. A jetton transfer, for example, involves a wallet contract for each side plus a master contract.

That changes how we design for failure. We plan for bounced messages, partial completion and gas for each step in the chain, and we test those paths. Tact gives readable code for most projects, and we use FunC when a project needs tighter control.

Telegram Mini Apps and payments

A Telegram Mini App is a web app opened inside Telegram. We build the interface, the sign-in with the user's Telegram data checked on the server, and the TON wallet connection. Payments can use TON or jettons through your own contracts.

Mini Apps depend on Telegram's platform rules, which can change, and payments follow Telegram's and the network's terms. We build to the current rules, but we cannot promise store approval, reach, virality or a user count.

A wallet or dApp MVP typically runs $8,500 to $16,000 and 3 to 4 weeks once the scope is agreed. Contract-heavy work such as staking or a DEX style product typically sits in the $14,000 to $28,000 range and 4 to 6 weeks. Ranges are typical and depend on scope and integrations. A written quote follows a scoping conversation. See pricing and packages. You own the code and the accounts you pay for.

Limits you should know about

Contracts on TON are public and a bug can mean lost funds. A security review lowers risk but cannot remove it; see audit and security review. We build software only, we do not hold your funds or give legal advice, and licences, KYC and compliance remain your responsibility. Real-money gaming features are only for operators who hold the licences their markets require.

How it works

  1. Tell us what you want to build

    A wallet, exchange, contract, bot or payment flow, and the chains involved.

  2. We scope and quote

    You get an architecture outline, a timeline and a written price range.

  3. We build in milestones

    Working builds are shared at each milestone, with a security review before launch.

Questions about crypto software agency in United States

Should my TON project use Tact or FunC?
Tact is our default for most projects because it reads closely to modern languages and reduces common mistakes. FunC gives lower-level control and is used when a project needs it or when you already have FunC code. We recommend one during scoping and explain why.
Can you build a Telegram Mini App with TON payments?
Yes. We build the Mini App front end, verify Telegram's init data on the server, connect wallets through TON Connect and write the contracts that receive payments. Payment flows follow Telegram's and TON's terms, which can change over time, so we build to the current rules and tell you what to watch.
Can you create a jetton token or NFT collection?
Yes. We build jetton and NFT contracts that follow the TON standards, with the minting, supply and admin rules you decide. Tokenomics, legal classification and marketing are your decisions and your responsibility, and we explain the technical effect of each rule so you can decide with the facts in front of you.
Can you guarantee my Mini App will be approved or go viral?
No, and nobody honestly can. Telegram sets its own platform rules, and growth depends on your product and marketing. We build a solid, tested app that follows current rules, and we tell you about platform risks we know of at the scoping stage.
How is TON development different from EVM development?
TON uses asynchronous message passing between contracts instead of synchronous calls, and different languages and tooling. The design and testing approach changes with it. If you are choosing a chain, we can compare TON with EVM chains for your use case.
