Over a two-month period, contributed to the use-ink/ink repository by developing and enhancing host functions for ink! smart contracts, focusing on resource management and EVM compatibility. Implemented a host function to expose block gas limits and reference time limits, enabling contracts to better manage execution resources. Expanded the Ink! Host Functions API to include EVM-like getters such as chain_id, balance_of, and block_hash, as well as data-size related functions, improving contract execution control and interoperability. The work involved comprehensive unit and integration testing, documentation updates, and code refactoring, utilizing Rust and blockchain development skills to ensure reliability and maintainability.
