Problem Statement 4: How can new technologies in digital wallets enable new trustworthy user experiences?

Short abstract of the project

With the advancement of tech, undeserved regions have trouble keeping up specifically with the lack of a stable internet connection. TikiWallet addresses this issue by introducing an innovative e-wallet solution that facilitates transactions even in areas with limited connectivity.

It introduces a unique dual-wallet system - online and offline. While supporting conventional online transactions between users, our platform empowers individuals to engage in secure, offline transactions using WiFi-direct technology, eliminating the dependence on traditional internet connectivity.
