## Deployment Details

### Successful Deployment
- **Address**: `0x9a1D0dBEE997929ED02fD19E0E199704d20914dB`
- **Transaction**: `0x4dc9f5eedf580c2b37457916b04048481aba19cf3c1a106ea1ee9eefa0dc03c8`
- **Method**: `forge create` with `--broadcast`
- **Gas Price**: 20 gwei (20000000000 wei)
- **Gas Limit**: 10,000,000 (required for successful deployment)
- **Status**: ✅ Deployed and confirmed

### Previous Attempts
- **First attempt**: Failed with 5M gas limit (hit gas limit, transaction reverted)
- **Solution**: Increased gas limit to 10M gas
- **Result**: ✅ Success

---

## Key Fixes Applied

### 1. Script Fixes
- ✅ Added `--broadcast` flag to Method 2
- ✅ Added `--gas-limit 10000000` (10M gas)
- ✅ Added RPC_URL validation and export
- ✅ Added on-chain verification for Method 1
- ✅ Script now properly tries all methods with verification

### 2. Gas Limit Issue
- **Problem**: 5M gas limit was insufficient
- **Solution**: Increased to 10M gas limit
- **Result**: Deployment succeeded

## Lessons Learned

1. **Gas Limit Critical**: Contract deployment requires sufficient gas limit (10M for this contract)
2. **Verification Important**: Always verify on-chain deployment before reporting success
3. **Multiple Methods**: Having fallback deployment methods is essential
4. **Export Variables**: Ensure variables are exported for subshell access
