# Phase 1 Implementation Status

Last Updated: 2026-03-27T21:52:00-07:00

## Build Status
- **Compile**: ✅ BUILD SUCCESSFUL
- **Unit Tests**: ✅ 163 tests pass, 0 failures
- **Test Coverage**: Core wallet, transaction, and payment flow logic

## Completed Components

### Core Wallet Infrastructure
- ✅ `CardanoWalletManager` - wallet state management with StateFlow
- ✅ `CardanoKeyStorage` - encrypted mnemonic storage with biometric protection
- ✅ `SeedPhraseManager` - BIP39 mnemonic generation/validation
- ✅ `BiometricAuthenticator` - biometric authentication wrapper
- ✅ `CardanoNetworkConfig` - testnet (preprod) configuration

### Transaction Building
- ✅ `DefaultTransactionBuilder` - transaction construction using cardano-client-lib
- ✅ `KoiosCardanoClient` - Koios API integration for UTXOs and protocol params
- ✅ `PaymentStatusPoller` - transaction confirmation polling
- ✅ Fee calculation from protocol parameters

### Payment Flow
- ✅ `/pay` slash command parsing
- ✅ Payment entry UI with validation
- ✅ Payment confirmation UI with fee display
- ✅ Payment progress UI with status tracking
- ✅ Payment event sending (using marker prefix format)

### Timeline Integration
- ✅ `TimelineItemPaymentContent` - payment card data model
- ✅ `TimelineItemContentPaymentFactory` - payment event parsing
- ✅ Custom event type handling via `MsgLikeKind.Other`

## Known Limitations

### sendRaw() SDK Binding
The Matrix Rust SDK does not currently expose `sendRaw()` for sending custom event types through the Timeline interface. Current implementation uses a message prefix marker (`$CARDANO_PAY$`) as a workaround.

**Impact**: Payment events appear as messages with special prefix instead of custom Matrix event types.

**Resolution**: When the Rust SDK adds Timeline.sendRaw() support, update:
1. `RustTimeline.kt` - implement actual call to `inner.sendRaw()`
2. `DefaultPaymentEventSender.kt` - switch from marker prefix to raw events
3. `TimelineItemContentFactory` - handle native custom events

The receiving side (`TimelineEventContentMapper`) already handles `CustomEventContent` from `MsgLikeKind.Other`.

## Test Summary

| Module | Tests | Status |
|--------|-------|--------|
| CardanoNetworkConfigTest | 7 | ✅ Pass |
| CardanoWalletManagerTest | 9 | ✅ Pass |
| PaymentStatusPollerTest | 4 | ✅ Pass |
| PaymentConfirmationPresenterTest | 4 | ✅ Pass |
| PaymentEntryPresenterTest | 8 | ✅ Pass |
| PaymentProgressPresenterTest | 7 | ✅ Pass |
| TimelineItemPaymentContentTest | 13 | ✅ Pass |
| TimelineItemContentPaymentFactoryTest | 14 | ✅ Pass |
| + Other wallet tests | ~97 | ✅ Pass |
| **Total** | **163** | ✅ Pass |

## Next Steps (Phase 2)

1. **Native custom events** - When Rust SDK exposes `sendRaw()`, implement proper custom event sending
2. **Address book** - Store/lookup Cardano addresses for Matrix users
3. **Payment receipts** - Store payment history locally
4. **QR code scanning** - For receiving addresses
5. **Mainnet support** - Configuration toggle and safety checks
