Worked on the foundry-rs/foundry repository to enhance the CLI by introducing a deterministic startup funding harness. Developed a new --fund-accounts flag, allowing users to initialize accounts with custom ETH balances at startup, which streamlines test setups and deployment scenarios. Implemented support for address:amount specifications to provide granular control over account funding. The work involved Rust programming and focused on blockchain development and CLI tooling. Refactored code to simplify HashMap imports and applied formatting improvements, contributing to better readability and maintainability. Collaborated closely with co-authors to ensure code quality through peer review and rigorous validation across the repository.
