Cryptocurrency wallets are the essential tools for users engaging with cryp- tocurrencies. Like many software projects, they use third-party code, forming a complex software supply chain. Given the high stakes associated with cryp- tocurrency incentives, these wallets are often targets of motivated adversaries. This thesis explores the dependencies in cryptocurrency wallets, emphasizing the challenges and risks posed by their software supply chain. To address these challenges, we employ the Design Science Research (DSR) methodology, devel- oping and evaluating a new tool, Dirty-Waters. This tool is designed to collect and analyze data from source code repositories and package registries. It aims to unveil the transparency status in the software supply chain of cryptocur- rency wallets. Our quantitative and qualitative results reveal a lack of concern about the transparency of different packages. These findings provide insights for enhancing secure dependency management.
