Solana Copy Trading Bot 🤖⚡

An advanced Solana copy trading bot designed for high-speed, secure, and automated DeFi trading. This project uses non-blocking parallel execution, must-selling protection, and multi-DEX fallback to safely copy trades on the Solana blockchain.

Built for reliability and performance, the bot ensures no missed sells, no blocked streams, and automatic balance management, even under heavy network load.

🚀 Key Features

• Solana Copy Trading – Automatically replicate target wallet trades in real time
• Parallel Transaction Processing – Buy and sell operations run concurrently without blocking the main stream
• Must-Selling Logic – Guaranteed sell attempts with retries and fallback strategies
• Multi-DEX Support – Native trading on PumpFun, PumpSwap, and Raydium with Jupiter API fallback
• Balance Monitoring Service – Continuous background checks to prevent stuck tokens
• Automatic SOL / WSOL Management – Smart wrapping and rebalancing after trades
• High Reliability – Designed to prevent lost transactions during network congestion

🏗️ Architecture Overview

Non-Blocking Main Stream

• Continuously monitors target wallets using Yellowstone gRPC
• Immediately submits buy/sell operations to parallel workers
• Never pauses or waits for transaction completion

Parallel Transaction Processor

• Each trade runs in an independent spawned task
• Multiple operations execute simultaneously
• Built-in retry logic and error handling per transaction

---

🔁 Must-Selling System (Fail-Safe Design)

Every sell operation follows a robust fallback sequence:

1. Native DEX Sell (3 retries)

   • PumpFun / PumpSwap / Raydium Launchpad
   • Ultra-low latency execution

2. Jupiter API Fallback (3 retries)

   • Automatically triggered if native DEX fails
   • Includes SOL/WSOL balance handling

3. Balance Verification

   • Confirms token balance before selling
   • Prevents unnecessary or failing transactions

This guarantees tokens are never left unsold.

🧠 Balance Monitoring & Automation

• Wallet scanned every 2 minutes by default
• Any remaining tokens are automatically sold
• SOL / WSOL balances are rebalanced after sells
• SOL is auto-wrapped to prepare for upcoming trades

This system acts as a self-healing safety net.
