Developed a configurable gas price scaling feature for the eth_gasPrice RPC within the matter-labs/zksync-os-server repository, enabling dynamic adjustment of gas prices based on network conditions. Leveraging Rust for backend and API development, the implementation introduced a gas_price_scale_factor parameter, defaulting to 1.5, which is applied to the base fee calculation. To ensure reliability and prevent regressions, comprehensive unit and integration tests were written, validating both the scaling logic and end-to-end RPC behavior. This work enhanced cost estimation accuracy for clients interacting with the network, providing greater flexibility and resilience in gas price determination through robust backend engineering practices.
