51+
52+
## Implementation Highlights
53+
54+
### Core Features
55+
- **Batch purchasing**: Buy tickets for multiple raffles in one operation
56+
- **Pre-validation**: All purchases validated before execution
57+
- **Individual simulation**: Each purchase simulated to check feasibility
58+
- **Partial failure handling**: Returns individual success/failure results
59+
- **Gas optimization**: Filters failed simulations to avoid wasted gas
60+
- **Detailed results**: Ticket IDs for successes, error messages for failures
61+
62+
### API Example
63+
64+
```typescript
65+
const result = await ticketService.buyBatch({
66+
purchases: [
67+
{ raffleId: 1, quantity: 3 },
68+
{ raffleId: 2, quantity: 5 },
69+
{ raffleId: 3, quantity: 2 },
70+
],
71+
memo: { type: 'text', value: 'Batch purchase' },
72+
});
73+
74+
// Result structure
75+
{
76+
results: [
77+
{ raffleId: 1, ticketIds: [101, 102, 103], success: true },
78+
{ raffleId: 2, ticketIds: [201, 202, 203, 204, 205], success: true },
79+
{ raffleId: 3, ticketIds: [], success: false, error: 'Raffle closed' }
80+
],
81+
txHash: '0xabc...',
82+
ledger: 12345,
83+
feePaid: '300000'
84+
}
85+
```
86+
87+
### Files Modified/Created
88+
89+
- ✅ `sdk/src/modules/ticket/ticket.types.ts` - Added batch types
90+
- ✅ `sdk/src/modules/ticket/ticket.service.ts` - Implemented buyBatch method
91+
- ✅ `sdk/src/modules/ticket/ticket.service.spec.ts` - Added comprehensive tests
92+
- ✅ `sdk/src/modules/ticket/README.md` - Updated documentation
93+
- ✅ `sdk/examples/buy-tickets-batch.ts` - Created working example
94+
- ✅ `sdk/BATCH_PURCHASE_IMPLEMENTATION.md` - Implementation guide
95+
- ✅ `sdk/package.json` - Fixed dependency version
96+
97+
## Design Decisions
98+
99+
### Sequential Execution
100+
Purchases execute sequentially rather than atomically because Soroban doesn't support true atomic multi-call in a single transaction. This allows partial success and better error reporting.
101+
102+
### Individual Simulation
103+
Each purchase is simulated before execution to:
104+
- Identify infeasible purchases early
105+
- Avoid wasting gas on failed transactions
106+
- Provide better error messages
107+
- Filter out bad purchases before execution
108+
109+
### Partial Failure Support
110+
The implementation continues processing even if some purchases fail, maximizing successful purchases and providing detailed feedback for failures.
111+
112+
## Next Steps
113+
114+
1. **Merge to main**: Ready for code review and merge
115+
2. **Integration testing**: Test against Stellar testnet
116+
3. **Contract optimization**: If contract adds native batch support, update implementation
117+
4. **Documentation**: Add to main SDK documentation site
118+
119+
## Notes
120+
121+
- Pre-existing error in `raffle.service.spec.ts` (line 153) - not related to this PR
122+
- All new code has zero diagnostics errors
123+
- Build completes successfully
124+
- Example code compiles without errors
125+
126+
## Ready for Review ✅
127+
128+
The batch ticket purchase feature is fully implemented, tested, and documented. All problems have been resolved and the code is ready for review and merge.
