Decentralized exchange (DEX) liquidity is fragmented across multiple blockchain networks (Ethereum, Arbitrum, Solana, Polygon, Optimism, and Base). Price discrepancies naturally arise across liquidity pools due to temporary trading imbalances. **Cross-Chain DEX Arbitrage** involves buying an asset at a lower price on a source chain DEX and simultaneously selling it at a higher price on a destination chain DEX.
However, executing profitable arbitrage requires accounting for **Price Impact** and network fees. Large order sizes relative to pool liquidity cause slippage, degrading execution prices. Additionally, cross-chain bridge fees, source/destination gas costs, and protocol swap commissions can quickly erase nominal arbitrage margins if not modeled in advance.
Step-by-Step Guide: How to Use the Suite
- Cross-Chain Arbitrage Calculator: Input trade capital, source DEX price, destination DEX price, and bridge costs to calculate net dollar profit and trade ROI.
- DEX Slippage & Price Impact Engine: Enter order size and pool liquidity depth to simulate constant-product AMM price impact and slippage loss.
- Route Gas & Bridge Net Yield Engine: Subtract multi-chain gas fees and DEX swap commissions from gross trade returns to verify net execution yields.
Key Concepts & Mathematical Principles
Constant Product AMM Price Impact Equation
In standard Automated Market Maker ($x \cdot y = k$) pools, price impact increases relative to trade order size vs total pool reserves:
Price Impact % = [ Order Size / (Pool Liquidity + Order Size) ] × 100
Net Arbitrage Profit Formula
Net trade profit accounts for gross price spreads across chains minus cross-chain bridge fees and execution costs:
Net Profit ($) = [ Trade Capital × (Dest Price - Source Price) / Source Price ] - Bridge Fees - Total Gas
Frequently Asked Questions (FAQ)
Q1: What is the difference between slippage and price impact?
Price impact is the price movement caused directly by your own order size relative to pool liquidity depth. Slippage is the price movement that occurs between transaction submission and block execution due to other pending trades.
Q2: How do cross-chain bridges affect arbitrage profitability?
Bridges charge protocol fees and impose settlement time delays. Fast bridge routes often charge higher fee percentages, which must be factored into net profit calculations.
Q3: Are calculations executed securely in my browser?
Yes. All mathematical calculations run 100% locally in your web browser via client-side JavaScript without requiring RPC connections or external API calls.
