• Proposal notifications

4. Identity & Verification (SDIS)

• View identity card with member stats
• Generate proofs (membership, age, reputation)
• Verify others via QR code scan
• Verification history tracking

5. Trust Graph

• View trust score on profile
• Attest trust for other members
• Trust score calculation (backend)

6. Offline Mode

• Queue operations when offline

SDK Methods

All methods implemented in @icn/react-native:

Authentication

• login(coopId, scopes) - Authenticate with cooperative
• logout() - Clear auth state
• initialize() - Load persisted session

Payments

• getBalance(coopId, did) - Get current balance
• pay(coopId, payment) - Send payment
• getHistory(coopId, options) - Transaction history

Governance

• listProposals(domainId) - List proposals
• getVotes(proposalId) - Get vote tally
• vote(proposalId, choice) - Cast vote

Identity

• getMemberProfile(coopId, did) - Get member profile
• verifyLevel1(qrData) - SDIS Level 1 verification

Trust

• attestTrust(coopId, target, score, metadata) - Attest trust
• getTrustScore(coopId, did) - Get trust score

Real-time

• connectRealtime(coopId) - Connect WebSocket
• disconnectRealtime() - Disconnect WebSocket
• onEvent(eventType, handler) - Subscribe to events

WebSocket Events

The app subscribes to these real-time events:

• PaymentCreated - New payment received or sent
• GovernanceProposalCreated - New proposal created
• GovernanceVoteCast - Vote cast on proposal
• TrustAttestationCreated - Trust attestation made
• IdentityVerified - Identity verification completed

Configuration

Gateway URL

Production: https://api.icn.zone

Edit in sdk/react-native/examples/CoopWallet/src/client.ts:

const GATEWAY_URL = 'https://api.icn.zone';

Secure Storage

• iOS/Android: Uses Expo SecureStore (hardware keychain)
• Web: Falls back to localStorage (development only)
