Proof of Passport App
Requirements
Install nodejs v18, circom and snarkjs
For android, install java, android studio and the android sdk
For ios, install Xcode and cocoapods
Installation
yarn
In /common, also run:
yarn
Build the app
Go to the circuit folder of the monorepo and build the circuit.
Build the android native module
Run:
./scripts/build_android_module.sh
You might need to set the rust-toolchain rust version as global default. Example:
rustup default 1.67.0
This you modify the circuits, you might have to modify ark-circom-passport/src/passport.rs too.
Build the iOS native module
Run:
./scripts/build_ios_module.sh
Now:
cd ios
pod install
./post_install.sh
cd ..
Run the server
To run the server, first connect your phone to your computer, allow access, then:
yarn start
Then press a for android or i for iOS
If you want to see the logs and have a better ios developer experience, open /ios in Xcode and launch the app from there instead.
⚠️ Due to the current limitations of mopro, see #51, the proving on iOS only works when the app is run on Xcode. It will not work with the react native server or in a .ipa build. We are working on fixing that.
To see the android logs you'll have to use the Android Studio Logcat.
To export an apk:
cd android
./gradlew assembleRelease
The built apk it located at android/app/build/outputs/apk/release/app-release.apk
Download zkey
If you want to mint a proof of passport SBT, instead of building the circuit yourself, run:
./scripts/download_current_zkey.sh
This will download the zkey currently deployed onchain in the proof of passport contract and place it in `circuits/build`` Then, build the android or iOS native module and run the app.
