PROFILE

Monica Jin

Over a three-month period, contributed to the polkadot-sdk and polkadot-docs repositories by focusing on resource accounting, benchmarking reliability, and developer documentation. Addressed gas and weight cost inaccuracies in execution tracing for nested child calls, introducing a PendingStep stack to improve EVM and PVM resource tracking using Rust. Enhanced the EVM Sized Benchmark Helper to generate precise contract sizes and updated stipend logic to strengthen security against reentrancy. Additionally, updated documentation in Markdown to ensure correct resolc version guidance for Hardhat compatibility, reducing installation issues. The work emphasized correctness, security, and improved onboarding for smart contract and blockchain development workflows.

Feb 2026 monthly summary for paritytech/polkadot-sdk: Delivered a critical bug fix to gas and weight cost accounting for nested child calls in execution tracing. Implemented exclusion of child call consumption from parent costs, tracked with a PendingStep stack, and subtracted upon parent completion. Expanded test coverage for nested call gas tracking in both EVM and PVM modes. This change improves resource accounting accuracy, debuggability, and pricing predictability for on-chain operations. Core PR: [pallet-revive] Fix gas_cost and weight_cost for nested calls in execution tracer (#10928).
