🎯 Best Practices

1. Smart Contract Security

- Use established libraries - Implement proper access controls - Test thoroughly - Audit contracts

2. Gas Optimization

- Optimize contract size - Use efficient data structures - Batch operations - Monitor gas usage

3. Network Management

- Use multiple RPC providers - Implement retry logic - Monitor network status - Handle network congestion

4. Wallet Security

- Use hardware wallets - Implement proper key management - Monitor transactions - Backup securely

5. Monitoring

- Track transaction status - Monitor gas prices - Alert on failures - Monitor contract events

🔧 Troubleshooting

Common Issues

1. Transaction Failures - Check gas limits - Verify network status - Review contract state - Check wallet balance

2. High Gas Costs - Optimize contract calls - Use batch operations - Monitor gas prices - Implement gas estimation

3. Network Issues - Use multiple RPC providers - Implement retry logic - Monitor network status - Handle timeouts

4. Security Issues - Audit contracts - Use established libraries - Implement access controls - Monitor for attacks

Debug Commands

Check contract status
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_call","params":[{"to":"0x...","data":"0x..."}],"id":1}' https://mainnet.infura.io/v3/YOUR_PROJECT_ID
Monitor gas prices
curl -X GET https://api.etherscan.io/api?module=gastracker&action=gasoracle&apikey=YOUR_API_KEY
Check transaction status
curl -X GET https://api.etherscan.io/api?module=proxy&action=eth_getTransactionReceipt&txhash=0x...&apikey=YOUR_API_KEY

🚀 Next Steps

1. Deploy smart contracts to mainnet 2. Set up monitoring and alerting 3. Implement DeFi protocols 4. Optimize gas usage 5. Monitor and maintain contracts
