Blockchain Engineering
Build production-grade applications, smart contracts, integrations, and operational tooling on TON (The Open Network). OQTACORE engineers in FunC, Tact, TVM assembly and ships products that match how TON works in production — not just how it works in a tutorial.
Get a senior TON team that already understands byzantine Fault Tolerant Proof-of-Stake, the TON toolchain, and the operational realities of running on TON (The Open Network).
Senior engineers, security-aware architecture, and an operations-ready handoff. Every engagement is scoped to your specific product, chain, and timeline.
Production smart contracts on the chain that fits the product, with the language, tooling, and patterns that chain expects.
Custodial, non-custodial, MPC, and enterprise wallet flows with the right balance of security, recovery, and UX.
Indexers, subgraphs, APIs, queues, and analytics so on-chain data shows up in your product without ad-hoc node calls.
Wallet connect, transaction UX, error handling, signed messages, gas estimation, and conversion-focused UI.
Audits, monitoring, key rotation, role separation, incident response, and operational handoff to your team.
Custody, KYC/KYB, payment rails, fiat on/off-ramps, and reporting integrations for regulated launches.
Predictable milestones, clear ownership, and a security pass on every meaningful change. No mystery between scoping and launch.
Map assets at risk, user roles, integrations, regulatory context, and acceptance criteria so we agree on what success looks like before any code is written.
Choose chain, language, contracts, services, and integrations. Lock in scope, milestones, ownership, and how third-party teams plug into the build.
Senior engineers ship in short cycles with code review on every change, security checklists per module, and tests written next to the code that needs them.
We re-read the code as adversaries: reentrancy, oracle and MEV exposure, access control, accounting precision, upgrade safety, and operational keys.
Deploy to testnets and staging environments with full frontend, indexer, and monitoring integration. Fix what only shows up under realistic conditions.
Coordinate audit findings, plan rollout, deploy with verification, set up monitoring and alerts, and stay on for the first weeks of production.
Tell us about your product, chain, timeline, and the outcome you need. We will reply within one business day with a clear next step — a scoping workshop, an audit, or a delivery plan.
Five fields. We respond within one business day.
We pick tools because they make the product safer, faster, or easier to operate — not because they are trending. Here is what tends to show up in ton development work.
TON powers products like Telegram Wallet, Notcoin, STON.fi, Tonkeeper. We design with that context in mind so your product fits user expectations and integrates with the tooling already used in the ecosystem.
Things to plan for on TON: Newer programming model than EVM; Smaller pool of senior security tooling; Specific patterns for asynchronous message handling.
We start with a short scoping workshop: target users, regulatory context, asset model, security requirements, integrations, and launch timeline. We then propose a delivery plan with milestones and acceptance criteria.
You can engage us for a focused build (smart contract, integration, DApp module), an audit-preparation effort, a chain migration from another ecosystem to TON, or a full product squad covering frontend, backend, contracts, QA, DevOps, and analytics.
Most engagements pair ton development with a few neighbours. Open the ones closest to your project to see how we deliver them.
Build blockchain networks, protocols, integrations, wallets, data services, and production Web3 applications.
Design, build, test, and deploy production smart contracts for DeFi, tokens, RWA, payments, DAOs, and Web3 apps.
Security review, automated scanning, manual exploit analysis, and remediation guidance before mainnet launch.
Custodial, non-custodial, MPC, mobile, browser, and enterprise wallets with secure transaction flows.
Decentralized applications with wallet flows, smart contracts, indexers, UX, backend services, and analytics.
Connect existing products to wallets, tokens, contracts, on-chain data, identity, payments, and custody.
The answers most teams ask for before scoping a project with us.
We have shipped Web3 products since 2017 and choose chains based on what the product actually needs. For TON, that means working in FunC, Tact, TVM assembly and respecting how byzantine fault tolerant proof-of-stake affects user experience, finality, and operations.
Typical builds include Telegram Mini Apps; Wallet and payment flows inside Telegram; Gaming with token rewards; Social and creator tokens.
Yes. We support migrations from other chains to TON and from TON to other chains, including data migration, contract translation, wallet UX changes, and operational handoff.
We provide internal security review and audit preparation. For high-value launches, we recommend pairing our work with an independent external audit firm familiar with TON.
Yes. OQTACORE can deliver the contracts, frontend, backend, indexer, wallet integration, analytics, admin panel, CI/CD, monitoring, and documentation as a single coordinated team.
