Developed and delivered per-transaction call results and transfer tracing for the EVM simulation in the morpho-org/sdks repository, enabling detailed tracking of transaction logs, status, return data, gas usage, and asset changes. This work involved a broad refactor of the simulation’s API and types, introducing new structures for call results and stabilizing behavior across both eth-simulate-v1 and tenderly-rest backends. The implementation, written in TypeScript and leveraging full stack development and testing skills, improved simulation correctness, safety checks, and documentation. Additional updates included enhanced test helpers, refined parsing logic, and targeted bug fixes to ensure robust and maintainable code.
