Challenges
Fragmented liquidity systems. The client needed one secure, automated environment to manage fiat and crypto liquidity.
Performance at trading scale. Peak loads reached 30,000 transactions per second, requiring millisecond-level execution without compromising fairness or stability.
Regulatory pressure on every transaction. The client’s EMI and VASP licenses required airtight KYC/KYB/KYT and Travel Rule compliance, plus full audit visibility to satisfy regulators.
Security that scales, without counterparty risk. Key management, signing, and risk controls had to stay in-house — within an architecture ready to expand across new assets, liquidity partners, and jurisdictions.
Solution
It features a full-stack trading and liquidity infrastructure with compliance at its core. Retail and institutional investors can securely place market, limit, and stop loss orders for fiat and cryptocurrencies. The liquidity is ensured by client reserves and designated market makers, connected via APIs.
By using FinTech core components, each user can also create a multi-currency bank account, as well as hold 20 different tokens in their cryptowallet. They can store and spend the held assets from the app or securely withdraw them to another bank account. All transactions – fiat or crypto — are monitored against custom anti-fraud and business rules and checked against AML compliance rules.
RESULTS
With the trust of our partners, we have created a solution that not only meets the needs of users but also aligns with their values and contributes to a more sustainable future.

Creation Process
Product vision
The client’s goal was clear: launch a unified liquidity platform where crypto and fiat could coexist under a single regulatory and technical framework. Together, we scoped the key requirements for a platform capable of institutional-grade trading across multiple asset classes with full EMI/VASP compliance, using Fintech Core as the starting point.
1Product Design
Our design sprint focused on simplifying complexity. User journeys were optimized for simplicity without compromising on compliance. Each prototype went through regulatory stress tests to guarantee a seamless experience backed by audit-proof integrity.
2architecture design
We engineered a modular architecture centered on a unified ledger and ExchangeCore-based matching engine. The stack combines in-memory processing, asynchronous event queues, and KMS-secured key management to deliver sub-40 ms latency and zero downtime. We also isolated compliance modules, wallet management, and liquidity logic into independent services to streamline future integrations.
3Delivery
The delivery phase ran in parallel tracks — front-end, back-office, and crypto infrastructure — synchronized through continuous integration pipelines. Each module was deployed and tested in a sandbox mirroring EMI-level operational conditions. Early testnets proved the engine could sustain 30,000 TPS while automated rebalancing kept liquidity ratios steady at 95/5.
4Extended Release
The extended release focused on broadening market reach. We expanded token support to 20+ assets, introduced APIs for external market makers, and added corporate multi-user roles with permission management. The system evolved from MVP to a fully compliant, multi-asset platform ready to onboard new jurisdictions and institutional partners without rewriting a single core module.
