Olga Kunyavskaya contributed to the Near-One/omni-bridge repository, delivering cross-chain interoperability features and robust smart contract enhancements over seven months. She engineered Bitcoin and ZCash integration, enabling seamless BTC and ZEC transfers with end-to-end test coverage, and improved token lifecycle management by refining fee processing and admin controls. Olga applied Solidity and Rust to implement secure proxy patterns, token standards, and CI/CD pipelines, while Docker and Hardhat were used to streamline deployment and testing. Her work addressed complex blockchain integration challenges, improved artifact management, and ensured reliable cross-chain transfers, reflecting a deep understanding of backend development and blockchain protocols.

January 2025 monthly summary for Near-One/omni-bridge: Implemented WebAssembly (WASM) CI Validation and Artifact Management. A dedicated CI workflow validates WASM assets, the build script now copies only relevant WASM files, and .gitignore was updated to exclude WASM artifacts from version control. These changes improve build reliability, artifact hygiene, and deployment consistency, reducing manual validation effort and risk of invalid artifacts reaching production.

December 2024: Key bug fix in Near-One/omni-bridge to correct fee processing. The Omni-Bridge now mints fees to the recipient at deployment rather than burning on ft_on_transfer, ensuring accurate revenue flow across token deployment states. This reduces fee leakage and improves reliability and predictability of token lifecycle and fees.

In 2024-11, Near-One/omni-bridge delivered the eNear token integration into the Omni Bridge, including deployment of the eNearProxy, updates to mint/burn logic, and accompanying documentation. The month also included a Hardhat project refactor with test migrations to improve build reliability and maintainability. Major reliability and correctness fixes were implemented through dependency cleanup with Borsh consistency improvements and a new token deployment balance safeguard.
