Anastasiia focused on enhancing EVM reliability and error handling in the neonlabsorg/neon-evm and neonlabsorg/neon-proxy.py repositories. She delivered features that improved precompiled transaction recognition by updating contract logic to correctly identify and execute precompile extension addresses. Using Rust and Python, she expanded error reporting by introducing structured error codes and detailed logging, enabling more precise debugging and transaction failure analysis. Her work included implementing a dataclass and error code enumeration to categorize transaction failures, along with new decoders and parsers for error interpretation. These changes deepened the robustness of transaction processing and debugging within Solana-based blockchain environments.
