Markin developed and integrated advanced backend features across cowprotocol/services and propeller-heads/tycho-simulation, focusing on robust system design and maintainability. He delivered a dynamic driver configuration override system for end-to-end tests, leveraging Rust and TOML parsing to enable flexible, per-run test setups. In cowprotocol/services, he built a settlement notification system that proactively informs external liquidity providers of upcoming settlements, supporting early risk management and improved pricing. For propeller-heads/tycho-simulation, he integrated the Liquorice protocol, streamlined error handling, and stabilized builds using Rust and GitHub Actions. Markin’s work demonstrated depth in protocol integration, configuration management, and continuous integration practices.
March 2026: Liquorice Protocol integration into Tycho Simulation Framework to enable multi-protocol experimentation; internal LiquoriceState return type simplified by removing a generic and streamlining error handling. Also resolved compilation issues to stabilize builds and completed the feature-branch merge to enable CI/testing coverage. The work broadens simulation capabilities, improves maintainability, and accelerates multi-protocol research workflows.

Delivered the Settlement Notification System for External Liquidity Providers in cowprotocol/services, enabling proactive notifications of upcoming settlements prior to on-chain submission. This supports earlier risk management and hedging, enabling better pricing for liquidity providers and users. The feature is implemented as a driver-level notifier (commit 8d03321f8075c2e930b489cdce9c6da2294f9d8f) under PR #3451. No major bugs reported this month; groundwork laid for broader LP integration and reliability improvements.
