Challenge

A gaming platform needed a reliable, secure way to accept crypto deposits and handle payouts. Storing keys on the main application server posed severe security risks, while watching blocks across five different networks (BTC, ETH, BSC, TRX, SOL) was complex, error-prone, and prone to silent failures.

Approach

Ships engineered a microservice-based TypeScript monorepo with an event-driven architecture using NATS. We isolated transaction signing into a dedicated service using HashiCorp Vault with an EVM plugin so keys never leave Vault. Watcher jobs deterministically derived player addresses via HD wallets, while automated sweeps and refills kept treasury operations fluid and secure.

Result

A rock-solid backend vault that handles multi-chain transactions, compliance blacklisting, AML checks, and secure signing with absolute reliability. The client received a secure, production-ready system with a clean administrative dashboard for operational monitoring.
