PROFILE
Mikhail Surin
Mike Surin contributed to the neonlabsorg/neon-evm repository by engineering features that advanced EVM emulation and cross-chain interoperability. He refactored transaction data handling to use transient memory and standard Rust Vec types, improving performance and maintainability. Mike introduced on-chain block hash retrieval via Solana syscalls, generalized slot hash providers, and modernized EVM state management for more reliable smart contract execution. His work included API development for emulating EVM transactions from holder accounts and enabling Solana calls without predefined lamport limits. Using Rust, Solidity, and deep knowledge of system programming, he delivered robust backend solutions and addressed complex data structure challenges.

Apr 1, 2025April 2025 (neon-evm) delivered two high-value features and advanced architecture to support multi-backend backends. No major bug fixes were recorded this month; focus was on delivering capabilities with strong validation and on refactoring for scalability. These efforts provide immediate business value through cross-chain interoperability and a more maintainable, extensible EVM loader.

Mar 1, 2025March 2025 performance summary for neon-evm: Delivered a key feature enhancing on-chain access to block hashes by refactoring the EVM Loader to retrieve block hashes via the sol_get_sysvar syscall and introducing a SlotHashesSysvarProvider for on-chain operations. Generalized the slot-hash retrieval to accept a generic provider, removed unnecessary account retrieval from RPC in the emulator, and optimized small buffer handling for memory efficiency. This work reduces on-chain RPC overhead, improves reliability of block hash data for smart contracts, and lays groundwork for future on-chain data providers.
