29 microservices delivered by a team of 6 Java engineers, 2 SDETs and 1 UI/UX designer. The platform combines Bitcoin, Ethereum/EVM and XRP wallet services with CLOB matching, KYC, custody, market data and crypto IPO workflows.

Professional digital-asset traders needed one venue for custody, deposits, withdrawals and real-time order-book trading across Bitcoin, Ethereum/EVM and XRP. The business also required controlled token and crypto-IPO launch workflows.

The exchange needed multi-chain wallets, KYC, 2FA, low-latency CLOB routing, market-data streaming and risk controls. It had to run as AWS services, support REST, WebSocket and FIX integrations, and give middle-office teams control.
We built SprinkleXchange as a containerised microservices digital-asset exchange.
Java/Spring Boot services manage balances, Bitcoin Core and Ethereum/EVM wallets, XRP operations, KYC, deposits, withdrawals, custody and 2FA. A CLOB stack - matching engine, order book, OMS and router - delivers real-time trading through JavaScript/Angular web apps, REST APIs, WebSockets and FIX.
Docker, Kubernetes and AWS provide deployment and scaling; ELK Stack supports operations. Portfolio, risk, price-chart, crypto IPO and middle-office services complete the post-trade platform.
As of 2025 - platform is discontinued or inactive for standard retail customer access.
