Advanced Bot Configuration

Gas Optimization

Konfigurasi gas untuk menghemat biaya transaksi:

                // config.js
module.exports = {
  gas: {
    maxFeePerGas: null,        // null = auto detect
    maxPriorityFeePerGas: null,
    gasLimit: 21000,            // Adjust per transaction type
    gasPriceMultiplier: 1.1,   // 10% above base fee
  }
}
            

Retry Logic

Implementasi retry untuk handle failed transactions:

                // Retry configuration
const retryConfig = {
  maxRetries: 3,
  retryDelay: 5000,      // 5 seconds
  exponentialBackoff: true,
  retryOn: ['NONCE_EXPIRED', 'TIMEOUT', 'NETWORK_ERROR']
}
            

Concurrency Control

Mengelola jumlah operasi paralel:

                // Limit concurrent operations
const { pLimit } = require('p-limit');
const limit = pLimit(5); // Max 5 concurrent

const promises = wallets.map(wallet => 
  limit(() => processWallet(wallet))
);
await Promise.all(promises);
            

Logging & Monitoring

Setup proper logging untuk debugging:

                // logger.js
const winston = require('winston');

const logger = winston.createLogger({
  level: 'info',
  format: winston.format.json(),
  transports: [
    new winston.transports.File({ filename: 'error.log', level: 'error' }),
    new winston.transports.File({ filename: 'combined.log' })
  ]
});
            

💡 Pro Tips

• Monitor gas prices dengan tools seperti Etherscan Gas Tracker
• Set up alerts untuk failed transactions
• Use nonce manager untuk handle concurrent transactions
• Implement circuit breaker pattern untuk handle outages
