Corda Development

Wallets, exchanges, DApps, tokenization, custody, and chain-specific buildsPermissioned distributed ledger for regulated finance

Build production-grade applications, smart contracts, integrations, and operational tooling on R3 Corda. OQTACORE engineers in Kotlin, Java and ships products that match how Corda works in production — not just how it works in a tutorial.

Get a senior Corda team that already understands notary-based finality (validating and non-validating notaries), the Corda toolchain, and the operational realities of running on R3 Corda.

What you get

What OQTACORE delivers in corda development

Senior engineers, security-aware architecture, and an operations-ready handoff. Every engagement is scoped to your specific product, chain, and timeline.

Smart contracts and protocols

Production smart contracts on the chain that fits the product, with the language, tooling, and patterns that chain expects.

Wallets and key management

Custodial, non-custodial, MPC, and enterprise wallet flows with the right balance of security, recovery, and UX.

Backend and indexing

Indexers, subgraphs, APIs, queues, and analytics so on-chain data shows up in your product without ad-hoc node calls.

Frontends and dApps

Wallet connect, transaction UX, error handling, signed messages, gas estimation, and conversion-focused UI.

Security and operations

Audits, monitoring, key rotation, role separation, incident response, and operational handoff to your team.

Compliance and integrations

Custody, KYC/KYB, payment rails, fiat on/off-ramps, and reporting integrations for regulated launches.

How we work

A six-phase corda development delivery you can plan around

Predictable milestones, clear ownership, and a security pass on every meaningful change. No mystery between scoping and launch.

Discovery and threat model

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.

Architecture and scope

Choose chain, language, contracts, services, and integrations. Lock in scope, milestones, ownership, and how third-party teams plug into the build.

Implementation

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.

Internal security review

We re-read the code as adversaries: reentrancy, oracle and MEV exposure, access control, accounting precision, upgrade safety, and operational keys.

Testnet and staging

Deploy to testnets and staging environments with full frontend, indexer, and monitoring integration. Fix what only shows up under realistic conditions.

Mainnet launch and run

Coordinate audit findings, plan rollout, deploy with verification, set up monitoring and alerts, and stay on for the first weeks of production.

Corda ecosystem context for corda development

Corda powers products like HSBC Contour, Marco Polo, Spunta Banca, B3i, SDX (SIX Digital Exchange). 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 Corda: Permissioned model — fewer open-network effects than public chains; Different mental model from EVM/account-based chains; Operationally heavier, requiring identity, networking, and notary planning.

How a Corda engagement starts

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 Corda, or a full product squad covering frontend, backend, contracts, QA, DevOps, and analytics.

FAQ

Corda Development — questions before you start

The answers most teams ask for before scoping a project with us.

Why pick OQTACORE for Corda development?

We have shipped Web3 products since 2017 and choose chains based on what the product actually needs. For Corda, that means working in Kotlin, Java and respecting how notary-based finality (validating and non-validating notaries) affects user experience, finality, and operations.

What can you build on Corda?

Typical builds include Bank-to-bank settlement and DvP; Trade finance and supply-chain finance; Tokenized securities and fund administration; Insurance and reinsurance workflows; CBDC and wholesale payment pilots.

Can you migrate an existing product to Corda?

Yes. We support migrations from other chains to Corda and from Corda to other chains, including data migration, contract translation, wallet UX changes, and operational handoff.

Do you handle audits on Corda?

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 Corda.

Can you build the full product, not just smart contracts?

Yes. OQTACORE can deliver the contracts, frontend, backend, indexer, wallet integration, analytics, admin panel, CI/CD, monitoring, and documentation as a single coordinated team.
