PMMA - Prediction Market Mobile App

How to run and test the app with local ganache

• Run impact-signalling project locally (from impact-signalling folder, manual is located in README.md)
  • install npm dependencies
  • compile contracts
  • run ganache
  • deploy contracts
  • update code (replace contracts addresses)
  • run web-app
• In impact-signalling web-app
  • add user (owner) with 10 tokens
  • create some markets
  • trade a bit (it's optional)
• Run mobile app
  • update SIGNALLING_ORCHESTRATOR address and LOCAL_GANACHE_HTTP
    • to get LOCAL_GANACHE_HTTP use ifconfig
  • yarn
  • yarn start
• Send money to mobile app user
  • get wallet adress from mobile (use COPY ADDRESS button)
  • in impact-signalling web-app add money for this address
  • send normal tx with 1 ether to this address (for being able pay for transactions on mobile)
• Watch prices on mobile and trade
  • Click on the markets icon (on the bottom menu bar)
  • Select a market
  • You can buy sell and watch the prices (chart, prices and balances data is updated automatically)

Important

• Built contracts JSON are copied from impact-signalling project, if they will be updated - you should copy the new versions

• You should send tokens and (!important) ethers for being able to send transactions from mobile app

• Don't forget to update SIGNALLING_ORCHESTRATOR and LOCAL_GANACHE_HTTP

• Your computer and mobile device should be in the same network (you can use something like ngrok instead, but it's quite slow)

• Ganache should be started with --host 0.0.0.0 parameter
