Lightweight Arbitrage Trading Bot for DEXs (Solana or BSC)
Budget: $10 – $30 USD
Arbitrage Trading Bot System Description
Objective
To develop a fast and efficient blockchain-based **arbitrage trading bot** that can identify and exploit small price differences between decentralized exchanges (DEXs) on **Solana** or **BNB Smart Chain (BSC)**.
The bot should be:
* Simple (not over-engineered)
* Fast (can monitor prices in real-time)
* Profitable (even with low capital, e.g., \$100–\$500)
* Cost-efficient (minimal gas fees)
* Secure (does not expose private keys)
---
Blockchain & DEX Focus
* **Primary Chains**:
* Option A: Solana
* Option B: Binance Smart Chain (BSC)
* **DEXs to Monitor**:
* On Solana: Jupiter, Raydium, Orca
* On BSC: PancakeSwap, 1inch, ApeSwap
---
Core Features
1. **Live Price Monitoring**
* Fetch token prices in real-time from 2–3 DEXs
* Compare token pairs like USDT/BNB, BUSD/BNB, etc.
2. **Arbitrage Opportunity Detection**
* Detect price differences that exceed a profitability threshold (e.g., 0.5–1% after gas fees)
3. **Gas Cost Awareness**
* Estimate gas costs before executing a trade
* Avoid unprofitable trades
4. **One-Click Execution (Optional)**
* Execute buy/sell in a single atomic transaction when profitable opportunity is found
5. **Logging & Dashboard (Optional)**
* Track past trades, profits, and missed opportunities
* Simple CLI or web dashboard (if required)
---
Technical Stack (Expected)
* **Languages**:
* Solana: Rust (preferred), or use SDKs via Python/TypeScript
* BSC: Python (web3.py) or JavaScript (ethers.js)
* **Tools & APIs**:
* DEX APIs (1inch, PancakeSwap, Jupiter, Raydium)
* Price feeds (Jupiter Aggregator, CoinGecko, or DEX Routers)
* RPC nodes (Ankr, QuickNode, Alchemy)
* **Wallet Management**:
* MetaMask (BSC) or Phantom (Solana)
* Use encrypted private key or hardware wallet integration
---
Performance Requirements
* Price refresh frequency: Every 2–3 seconds or faster
* Execution latency: Under 1 second ideal
* Low resource usage: Should run on low-cost VPS or local machine
* Support for small capital: \$100–\$500 minimum workable size
---
Security Requirements
* No private key hardcoding in source code
* Use secure signing (offline tx signing or encrypted secrets)
* Built-in checks to avoid front-running and failed trades
---
Future Enhancements (Optional, not in MVP)
* Multi-token pair scanning (5–10 pairs)
* Limit orders (e.g., only act at certain thresholds)
* Telegram alerts for arbitrage opportunities
* Multi-chain scanning (add Polygon, Arbitrum later)
Deliverables
1. Source code (well-documented and open for modification)
2. Setup guide (how to run and maintain the bot)
3. web/CLI interface
4. Deployment & testing on live environment
