AaryaPay is a proof-of-concept mobile payment application that implements an offline P2P transaction protocol developed as a part of a research project. It is built using Golang with its Gin framework and utilizes PostgreSQL and Redis as the DBMS. Traefik is employed as a reverse proxy, while Nginx serves static files.
