Solana implementation of Upala protocol

This project demonstrates how to use the Upala to interact with programs on the Solana blockchain.

The project comprises of:

• An on-chain upala program on C
• A client that can send:
  • npm run create-group for the create new Upala group
  • npm run add-user for adding the new user to Upala group
  • npm run empty-pool to go out with the bank from Upala group
  • npm run remove-groups a simple clean the program storage

Quick Start

The following dependencies are required to build and run this example, depending on your OS, they may already be installed:

• Install node (v14 recommended)
• Install npm
• Install the latest Rust stable from https://rustup.rs/
• Install Solana v1.6.6 or later from https://docs.solana.com/cli/install-solana-cli-tools

If this is your first time using Rust, these Installation Notes might be helpful.

Install npm dependencies

$ npm install

Build the on-chain program

$ npm run build:program-c

Deploy the on-chain program
