WeiPay ERC20 Wallet

WeiPay is a open source cryptocurrency wallet available for both IOS and Android mobile devices. WeiPay will support Ethereum out of the box with added support for ERC20 tokens and Bitcoin. An api will be created to host token details on IPFS in order for any fork of the wallet to provide uniform data to its users with the added benefits of reduced app storage space.

Clean Clone to Build to IOS Device

• git clone https://github.com/ChainSafe/WeiPay.git
• npm install or yarn install
• react-native link
• React Native/Xcode build issue
  • Double Conversion Errors -> Xcode -> Libraries -> RCTWebSocket.xcodeproj -> Build Phases - > Link Binary with Libraries -> select libfishhook.a and click " - " button. Click " + " and add libfishhook.a to add the broken dependency.
  • https://github.com/facebook/react-native/issues/19839
  • React Native third party library issue -> https://github.com/facebook/react-native/issues/14382
  • Solution: CD /node_modules/react-native/third-party/glog & ./configure
  • This will throw one last error in xcode, you must change the return value of the function to NULL and comment out the current return statement (return (void*)context->PC_FROM_UCONTEXT;).
  • https://github.com/facebook/react-native/issues/16106
  • Build & run project -> select developer profile -> make sure deployment targets are the same in both your project and the tests project -> WeiPay should build to your physical ios device

How To:

• git clone https://github.com/ChainSafe/WeiPay.git
• npm install, sudo npm install (if on linux)
• react-native link
• git checkout -b yourBranchName

Software Requirements

• Node 8.0 +
• XCODE - For IOS Build
• Android Studio - Android Build

• JDK >= 1.7 (if you run on 1.6 you will get an error on "_cameras = new HashMap<>();")
• On Android, you require buildToolsVersion of 25.0.2+. This should easily and automatically be downloaded by Android Studio's SDK Manager.
• Java should be in your system path

Run on Simulator

• IOS: react-native run-ios

• Android: react-native run-android
