In March 2026, Max Petrov developed a configurable gas price scaling feature for the eth_gasPrice RPC within the matter-labs/zksync-os-server repository. Using Rust and focusing on backend and API development, Max introduced a gas_price_scale_factor parameter, defaulting to 1.5, which dynamically adjusts the base fee returned by eth_gasPrice. This addition allows clients to better estimate transaction costs under varying network conditions. Max ensured reliability by implementing comprehensive unit and integration tests that validated both the scaling logic and end-to-end RPC behavior. The work demonstrated a focused, in-depth approach to enhancing API flexibility and robustness without addressing unrelated bugs.
