PROFILE

Igor Markin

Over a three-month period, this developer enhanced the cowprotocol/services repository by implementing dynamic driver configuration overrides for end-to-end tests using Rust and TOML parsing, improving test flexibility and maintainability. They also delivered a settlement notification system that proactively informs external liquidity providers of upcoming settlements, supporting early risk management and better pricing through backend development and smart contract integration. In the propeller-heads/tycho-simulation repository, they integrated the Liquorice protocol to enable multi-protocol experimentation, streamlined error handling, and stabilized builds with continuous integration. Their work focused on robust system design, maintainable code, and expanding simulation and testing capabilities across multiple protocols.

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.
