Blockchain Automation Tools
Automated On-chain Operations & Monitoring
Python Node.js Docker Web3.js Telegram Bot
Overview
Developed a suite of automation tools for blockchain operations — covering airdrop farming workflows, transaction monitoring, wallet management, and notification systems across multiple chains.
Key Tools
Multi-chain Transaction Automation
- Built batch transaction executors for Ethereum, Arbitrum, Optimism, and Solana
- Implemented gas price optimization with EIP-1559 fee estimation
- Created scheduling system for time-sensitive on-chain operations (e.g., token claims, governance votes)
Wallet Portfolio Manager
- Developed multi-wallet balance aggregator supporting EVM and Solana wallets
- Built DeFi position tracker pulling data from lending and liquidity protocols
- Implemented P&L calculation with historical price lookups
Alert & Notification System
- Built Telegram bot for real-time alerts on wallet activity and price movements
- Implemented smart contract event listeners for protocol-specific notifications
- Created customizable threshold alerts for gas prices and token prices
Airdrop Workflow Engine
- Designed task orchestration framework for multi-step airdrop qualification
- Built transaction randomization (timing, amounts, paths) for organic activity patterns
- Implemented progress tracking and completion scoring per wallet
Technologies
- Backend: Python (web3.py, asyncio), Node.js (ethers.js)
- Automation: Docker, cron jobs, PM2 process manager
- Notifications: Telegram Bot API, Discord webhooks
- Data Storage: SQLite for transaction logs, Redis for caching
Results
Automation tools significantly reduced manual operational overhead, enabling efficient management of multi-chain activities with consistent execution and real-time visibility.
