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.
Currently, proof generation seems to fail sometimes with the react native server, so prefer using Xcode instead.
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.
