Worked on the paritytech/foundry-polkadot repository to extend authorization capabilities for EIP-7702 cheatcodes, enabling support for multiple authorizations and active delegations within transaction workflows. Focused on improving transaction security for multi-party scenarios, the implementation introduced a vector for active delegations and updated nonce handling to accommodate multiple delegations. Comprehensive tests were added to validate the new multi-authorization functionality and ensure backward compatibility with existing cheatcodes. The work emphasized code quality and robust test coverage, aligning with business priorities for scalable, secure transaction flows. Utilized Rust for blockchain and smart contract development, with a strong emphasis on thorough testing practices.
