High-Performance Market Making Engine in Go

How we built a private execution system so an investor could manage significant DeFi volume without relying on third-party platforms.
A private investor needed a proprietary execution engine to automate liquidity providing strategies on Uniswap. The challenge was twofold: quickly getting up to speed on DeFi domain concepts (concentrated liquidity, tick ranges) and translating them into performant software capable of managing real capital without the security risks of third-party platforms.
Relying on manual execution or third-party tools limited speed, privacy, and control over high-value trading operations.
Validate whether a private execution engine could be built quickly enough to capture the market opportunity while keeping strategy logic and infrastructure under the client's control.
In two weeks, we analysed the domain and built the engine in Go, chosen for its concurrency model and type safety. We designed the architecture to be modular and extensible: the core handles smart contract interaction, while trading strategies are isolated plug-ins. For security and data sovereignty, the system was built for self-hosted deployment on private infrastructure. We built a minimal operational interface covering wallet connection, position monitoring, and fast switching between liquidity allocation strategies.
The client moved from manual or third-party execution to a private system they controlled. It handled €100k+ per day, allowed new strategies to be added without rebuilding the core, and reduced dependency on external platforms for high-value trading operations.
