The Strategic Solution
Implementation of a compiled Rust backend and WebAssembly parsing layer to offload binary data processing from JavaScript.
Architectural Implementation
The Challenge of Real-Time Settlement
The legacy settlement system was losing trades due to polling-based architecture that couldn't keep up with market volatility. At peak times, latency could spike to over 500ms, making it impossible to execute high-frequency trades effectively. Off-the-shelf fintech integrations were too rigid and generic to handle the specific liquidity demands of their market making strategy.
Impetix was brought in to architect a new system from the ground up, with a mandate to achieve sub-50ms latency. We rejected the low-code integration path and implemented a WebSocket-driven event stream in Rust. This bespoke architecture reduced latency by 90% and has successfully handled multiple million-user events without a single dropped trade—performance that no generic SaaS API could match.
