The problem PRAVA solves

The Financial Inclusion Challenge

Limited Internet Connectivity: Many rural and remote areas suffer from inconsistent or non-existent internet access.
Non- viability of Digital currencies: CBDCs or any digital currencies can't be used when offline and that defeats the purpose of universability of digital money.
Transaction Failures: Frequent failures due to connectivity issues, leading to mistrust in digital payments.

Challenges we ran into

1. Couldn't find any DLT provider to build our SMS protocol, so we started building a relay application:
   Initially, we struggled to find a Distributed Ledger Technology (DLT) provider to support our SMS protocol needs. Consequently, we decided to develop a custom relay application, allowing us to maintain control and ensure seamless message delivery.

2. Our initial tech choice for building the app was React Native, but we switched our app tech stack to Flutter:
   We initially chose React Native for app development due to its cross-platform capabilities. However, it didn't had SMS support as we needed, so we switched to Flutter.

3. Had troubles signing transactions, so we had to create a smart wallet to facilitate our transactions:
   Encountering difficulties with transaction signing and execution, we developed a smart wallet solution. This wallet automates and secures the transaction process, ensuring smooth and reliable execution within our application ecosystem.
