Worked on the Consensys/linea-tracer repository to deliver and validate the integration of the hub shomei component, focusing on replay-based testing to ensure stability and accuracy. Developed the UpdatedShomeyTests Java test class within the arithmetization module, leveraging Java for integration testing and blockchain tracing. The approach involved configuring tests to replay historical transaction data using compressed data files, which expanded regression coverage and validated the integration under realistic conditions. No major bugs were addressed during this period, as the primary emphasis was on building robust test infrastructure and improving test coverage for the new feature within the blockchain tracing workflow.
