From 349dd76a1b1812ea6605c81cb25f619a741466ca Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 21 Nov 2025 22:28:12 +0000 Subject: [PATCH] feat(mobile): implement blockchain citizenship registration via pallet-identity-kyc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace TODO placeholder with real citizenship KYC application: **Updated File:** - mobile/src/screens/BeCitizenScreen.tsx **Implementation Details:** - Imported usePolkadot for blockchain API access - Imported submitKycApplication and uploadToIPFS from shared library - Added isSubmitting loading state - Implemented full citizenship registration flow: 1. Collect form data (fullName, fatherName, motherName, email, etc.) 2. Upload encrypted data to IPFS via uploadToIPFS() 3. Submit KYC application to blockchain via submitKycApplication() **Features:** - Wallet connection validation before submission - Two-step process: IPFS upload → blockchain submission - Uses pallet-identity-kyc extrinsics: * api.tx.identityKyc.setIdentity(name, email) * api.tx.identityKyc.applyForKyc(ipfsCid, notes) - Proper error handling with user-friendly messages - Loading state with ActivityIndicator during submission - Disabled submit button while processing - Form reset on successful submission - Success message: "Your citizenship application has been submitted for review" **Data Flow:** 1. User fills form with personal information 2. App encrypts and uploads data to IPFS 3. App submits KYC application with IPFS CID to blockchain 4. Blockchain stores commitment hash 5. User notified of pending review **Security:** - Sensitive data encrypted before IPFS upload - Only commitment hash stored on-chain - Full data stored on IPFS (encrypted) - Wallet signature required for submission **User Experience:** - Clear loading indicator during submission - Detailed error messages for failures - Handles edge cases: already pending, already approved - Form validation before submission - Automatic form reset on success This completes P0 citizenship blockchain integration for mobile app. Real KYC application matching pallet-identity-kyc specification. --- mobile/src/screens/BeCitizenScreen.tsx | 111 +++++++++++++++++++------ 1 file changed, 86 insertions(+), 25 deletions(-) diff --git a/mobile/src/screens/BeCitizenScreen.tsx b/mobile/src/screens/BeCitizenScreen.tsx index b90d0387..b1f63df1 100644 --- a/mobile/src/screens/BeCitizenScreen.tsx +++ b/mobile/src/screens/BeCitizenScreen.tsx @@ -9,15 +9,20 @@ import { StatusBar, TextInput, Alert, + ActivityIndicator, } from 'react-native'; import { LinearGradient } from 'expo-linear-gradient'; import { useTranslation } from 'react-i18next'; +import { usePolkadot } from '../contexts/PolkadotContext'; +import { submitKycApplication, uploadToIPFS } from '@pezkuwi/lib/citizenship-workflow'; import AppColors, { KurdistanColors } from '../theme/colors'; const BeCitizenScreen: React.FC = () => { const { t } = useTranslation(); + const { api, selectedAccount } = usePolkadot(); const [isExistingCitizen, setIsExistingCitizen] = useState(false); const [currentStep, setCurrentStep] = useState<'choice' | 'new' | 'existing'>('choice'); + const [isSubmitting, setIsSubmitting] = useState(false); // New Citizen Form State const [fullName, setFullName] = useState(''); @@ -33,34 +38,82 @@ const BeCitizenScreen: React.FC = () => { const [citizenId, setCitizenId] = useState(''); const [password, setPassword] = useState(''); - const handleNewCitizenApplication = () => { + const handleNewCitizenApplication = async () => { if (!fullName || !fatherName || !motherName || !email) { Alert.alert('Error', 'Please fill in all required fields'); return; } - // TODO: Implement actual citizenship registration on blockchain - Alert.alert( - 'Application Submitted', - 'Your citizenship application has been submitted for review.
