Smart contract deployment costs constitute an economic consideration in blockchain ecosystems, yet existing gas optimization approaches primarily focus on execution efficiency while neglecting deployment gas reduction. We analyze Solidity storage internals and identify that conventional variable packing–despite reducin...
Across 31 applications on AWS Lambda, PyXtrim reduces cold-start latency by 21.7% and peak memory usage by 17.1% at the median, more than double the reduction achieved by the state of the art, while debloating each application in minutes.

This paper designs a realistic and controlled experimental environment, evaluating 33 CVEs across 20 real-world projects and two popular ACR pipelines, to assess the susceptibility of real-world ACR pipelines to vulnerability re-introduction attacks and finds that template-based attacks are ineffective and may even bac...

Modern infrastructures rely on Infrastructure as Code (IaC) systems to keep complex deployments consistent, reproducible, and scalable at production scale. The reliability of these infrastructures, however, depends on the correctness of their building blocks, which are reusable components (modules) that each performs a...
