EthGlobal Istanbul
We are enhancing a well-known Open Vote Network (OVN) protocol with an iOS app and gasless vote casts for a great user experience. We are using WalletConnect for the iOS app and ERC4337 paymaster protocol.
We are reusing the voting protocol from zkSNARK-Open-Vote-Network
Project strucutre:
SmartContract: contains the OVN smart contracts and the zkSNARK circuits.delegate: contains the iOS app delegate (the iOS companion app that should be merged into the native iOS app in the future)iOSApp: contains the iOS app
The smart contracts have been deployed on the Goerli Linea Network Using following commands:
truffle migrate --network linea_testnetcd scriptstruffle exec deploy.js --network linea_testnettruffle exec register.js [userId] --network linea_testnettruffle exec castVote.js [userId] [true/false] --network linea_testnettruffle exec tally.js --network linea_testnet
See the smart contract address at Blockscout.
