Transaction Performance
The deployment executed flawlessly with optimal gas efficiency:
- Chain ID: 8163 (SVM Testnet)
- Total Gas Used: 4,931,423 gas
- Average Gas Price: ~1 gwei
- Total Cost: 0.00493 ETH equivalent
- Status: ✅ SUCCESS
Transaction Hashes:
0x2883f2d588c5f5d0bc2a85f359511b37f6793ff6605f4182b5b71b9edc179b120x862fc4f54eec4f2a430efc913f9bd37b48acead68182e8e4d246bded00999d40
Fee Market Validation
Beyond successful deployment, we've confirmed that the fee market is behaving exactly as expected! This is crucial for:
✅ Predictable transaction costs
✅ Fair priority fee mechanisms
✅ Network sustainability
✅ Developer confidence
The gas pricing remained stable throughout the complex multi-contract deployment, demonstrating robust economic design.
🔍 Verify on Explorer
All deployed contracts are now live and verifiable on our BlockScout explorer:
https://evmscan.steemscanner.com
You can:
- Inspect contract source code
- View transaction details
- Monitor contract interactions
- Track token transfers
- Analyze gas usage patterns
What This Means
Successfully deploying Uniswap V4—a sophisticated, production-grade DeFi protocol—proves that SVM can handle:
- Complex smart contracts with intricate logic
- Large-scale deployments with multiple interdependent contracts
- Real-world DeFi infrastructure requirements
- Efficient gas optimization for cost-effective operations
This brings us significantly closer to mainnet readiness and demonstrates that Steem can support a thriving DeFi ecosystem.
