PROFILE

Diana Carvalho

Dian Okka contributed to the Tycho project by developing and enhancing backend components across the tycho-execution, tycho-indexer, and tycho-protocol-sdk repositories. Over two months, Dian delivered features such as protocol executor deployments, encoding improvements, and MEV-resistance enhancements, focusing on DeFi protocol integration and smart contract reliability. Using Rust, Solidity, and JavaScript, Dian addressed token normalization issues, improved error handling for native and wrapped tokens, and expanded integration testing coverage. The work included codebase refactoring, dependency upgrades, and configuration management, resulting in more robust, maintainable systems that support safer cross-protocol interactions and streamlined deployment workflows for DeFi applications.

July 2025: Delivered MEV-resistance enhancements for EkuboExecutor and aligned monitoring/deployment with the Tycho project across tycho-execution and tycho-simulation. Implemented deployment/script updates for MEV resistance, updated Tenderly project association to Tycho, and upgraded tycho-execution to enable a new Ekubo executor with MEV resistance. These changes reduce MEV-related risk, standardize configuration across repos, and establish a scalable upgrade path for Ekubo-based workflows.

June 2025 monthly summary: Delivered critical fixes and feature work across Tycho Execution, Indexer, and Protocol SDK, enhancing encoding reliability, expanding protocol support, and strengthening test coverage. Key improvements include Curve Encoding Bug Fixes (token normalization, native/wrapped token handling, post-rebase adjustments), Curve/Swap Encoding improvements (ETH/WETH input handling, removal of unnecessary clones, and excluding foundry files), deployment of Balancer V3 and Bebop executors, and a broadened protocol test suite. In addition, codebase maintenance included renaming CurrencyToken to Token and dependency upgrades, plus a migration cleanup in the protocol SDK. Result: more robust, scalable, and maintainable components, enabling safer cross-protocol interactions and faster deployment cycles.
