Market Making on Uniswap: High-Performance Engine in Go
We built a custom liquidity providing system capable of running multiple strategies and handling hundreds of thousands of euros in daily transactions.
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.
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.
We shipped a production-ready system handling hundreds of thousands of euros daily. The client got a fully private technology asset with no intermediaries, able to implement new market logic independently. Going from concept to execution that fast meant capturing DeFi market opportunities with a system that actually holds up.
