TON Blockchain Development Company

TON Blockchain Development

We integrate the TON blockchain into Telegram products: wallet connection through TON Connect, TON and USDT payments, Jetton and NFT contracts in FunC or Tact, escrow and staking logic, and the indexing and backend services that make on-chain data usable inside a Mini App. Engagements start at $6,000 for a payment integration and run to $60,000+ for full DeFi products.

TON and Telegram: why they fit

TON (The Open Network) is the blockchain Telegram chose for its Wallet, for Telegram Stars conversion and for ad revenue sharing with channel owners. A Mini App can ask the user to connect a wallet through TON Connect, and if the user has the built-in Telegram Wallet the flow stays inside Telegram. That removes the biggest obstacle in crypto UX: installing and funding a wallet.

For businesses this means payments without card processors, loyalty points that users can actually own and trade, game items with real scarcity, and access to a user base that already holds TON and USDT.

What we build on TON

Payments

TON Connect integration with the Telegram Wallet, Tonkeeper and MyTonWallet.
TON and USDT payments with backend confirmation via indexers, idempotent order handling and refunds.
Hybrid checkout: Stars for digital goods (required by Telegram), TON for everything else.

Tokens and NFTs

Jetton contracts with mint, burn and vesting controls.
NFT collections for access passes, game items and certificates, with metadata hosting.
Airdrop and claim contracts with Merkle proofs, snapshot tooling and Sybil filtering.

DeFi and marketplace logic

Escrow for peer-to-peer deals inside Telegram communities.
Staking and reward distribution.
Swap and liquidity integrations with STON.fi and DeDust.
Marketplaces for NFT items with royalties.

Backend and data

Indexers for on-chain events, webhooks to your systems, caching for fast Mini App screens.
Key management, deploy scripts, monitoring of contract balances and failed transactions.

How a TON project runs

Design (1 week). What goes on-chain and what stays off-chain. Most products need only a fraction of their logic on-chain; the rest is faster and cheaper in a database.
Contracts (2–6 weeks). Tact or FunC, unit tests in the TON sandbox, testnet deployment, gas profiling.
Integration (2–4 weeks). TON Connect in the Mini App, backend confirmation, UX for pending and failed transactions.
Audit and launch (1–3 weeks). Third-party audit, fixes, mainnet deployment, monitoring.

Compliance note

Token launches, custody and exchange features carry regulatory obligations that differ by jurisdiction (US, UK, EU MiCA, UAE VARA). We build the technology; legal structuring, licensing and listings are handled by your counsel and partners. We are happy to work alongside them from the design stage.

TON Blockchain Development: FAQ

What can TON add to a Telegram Mini App?

Payments in TON or USDT without card fees, tokens and NFTs as rewards or access passes, on-chain ownership for game items, and DeFi features such as swaps or staking. The Telegram Wallet makes the first transaction a two-tap flow for users who already have a balance.

How much does TON integration cost?

Accepting TON or USDT payments through TON Connect costs $6,000–$12,000. A Jetton with distribution tooling costs $10,000–$25,000. NFT collections, escrow or staking products run $20,000–$60,000 plus audit fees.

FunC or Tact?

Tact for most new contracts: it is readable, safer by default and well supported. FunC when we need maximum control over gas or are extending existing FunC code. We write tests for both with the TON sandbox.

Do you audit smart contracts?

We write tests and run internal reviews, and we coordinate third-party audits from established TON auditors before mainnet deployment. Audit cost depends on contract size and is quoted separately.

Can users without crypto experience use it?

Yes, if the product is designed for it. We default to the Telegram Wallet, hide gas details behind clear messages, support Stars as a fiat-like fallback and keep on-chain actions optional where regulation allows.
