# StealthAuction Deployment Summary

## Network Information
- **Network**: $NETWORK
- **RPC URL**: $RPC_URL
- **Deployment Time**: $(date)

## Deployed Contracts

### Core Contracts
- **StealthAuction Hook**: \`$HOOK_ADDRESS\`
- **Pool Manager**: \`$POOL_MANAGER_ADDRESS\`

### Tokens
- **Token0**: \`$TOKEN0_ADDRESS\`
- **Token1**: \`$TOKEN1_ADDRESS\`
- **Auction Token**: \`$AUCTION_TOKEN_ADDRESS\`

## Features Deployed
- ✅ FHE-powered Dutch auctions
- ✅ Encrypted bidding system
- ✅ Uniswap v4 hook integration
- ✅ 3-hook system (beforeSwap, afterSwap, beforeAddLiquidity)
- ✅ Comprehensive test suite (117 tests passing)

## Demo Results
The demo successfully demonstrated:
1. **Encrypted Auction Creation** - Auction parameters stored encrypted on-chain
2. **Private Bidding** - Multiple bidders submit encrypted bids
3. **Price Decay** - FHE-computed price decay over time
4. **Settlement** - Encrypted computation of winning bids
5. **Parameter Revelation** - Optional post-auction transparency

## Next Steps
1. Use the deployed contracts for FHE Dutch auctions
2. Integrate with frontend applications
3. Monitor auction performance and gas usage
4. Scale to production networks

## Files Generated
- \`deployment-summary.md\` - This summary
- \`.env\` - Environment variables with deployment addresses
- \`anvil.log\` - Local network logs (if using Anvil)

## Test Results
All 24 integration tests passed, confirming:
- FHE integration functionality
- Hook permission system
- Auction lifecycle management
- Error handling and edge cases
