Blockchain Engineering
Build production-grade applications, smart contracts, integrations, and operational tooling on Aptos. OQTACORE engineers in Move and ships products that match how Aptos works in production — not just how it works in a tutorial.
Get a senior Aptos team that already understands aptosBFT (modified HotStuff), the Aptos toolchain, and the operational realities of running on Aptos.
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 aptos development work.
Aptos powers products like LiquidSwap, Topaz, Pancake on Aptos. 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 Aptos: Move ecosystem still maturing; Smaller validator and audit pool than EVM majors.
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 Aptos, or a full product squad covering frontend, backend, contracts, QA, DevOps, and analytics.
Most engagements pair aptos 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 Aptos, that means working in Move and respecting how aptosbft (modified hotstuff) affects user experience, finality, and operations.
Typical builds include Consumer payments; Gaming with parallel execution; Tokenization; High-throughput DeFi.
Yes. We support migrations from other chains to Aptos and from Aptos 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 Aptos.
Yes. OQTACORE can deliver the contracts, frontend, backend, indexer, wallet integration, analytics, admin panel, CI/CD, monitoring, and documentation as a single coordinated team.
