DEFI DeFi Arbitrage Bot Strategies

Strategy 1: Cross-DEX Arbitrage

Simple arbitrage:

Asset: ETH/USDT
DEX 1: Uniswap (price $1,850)
DEX 2: SushiSwap (price $1,855)
Profit: $5 per ETH
Gas: ~$2
Net profit: $3 per ETH

Automation:

• Monitor multiple DEXs simultaneously
• Execute when spread > gas cost + profit margin
• Multi-chain arbitrage (Ethereum → BSC → Polygon)
• Flash loans for capital efficiency

2025 results:

• Average profit per trade: $5-25
• Success rate: 67%
• Gas optimization critical
• Competition increasing

Strategy 2: Cross-Chain Arbitrage

Bridge arbitrage:

Asset: USDC
Chain 1: Ethereum (price $0.9998)
Chain 2: Polygon (price $1.0002)
Bridge cost: $0.001
Net profit: $0.0004 per USDC
Scale: $100,000 = $40 profit

Automation:
