Monitoring Cross-DEX Pool Price Spreads After Gas Costs
Summary
The document shows a live monitor comparing executable buy and sell quotes across decentralized exchange pools for several crypto pairs and chains. For a stated trade size of 10,000 stablecoins, it selects the best buy pool and best sell pool, reports gross spread and profit, estimates gas expense, and calculates net profit. It also compares prices with Binance and records whether a trade is indicated.
In the displayed snapshot, every listed opportunity has negative net profit and is marked as unavailable, illustrating how pool differences can disappear after costs. This is a monitoring example, not evidence of realized arbitrage returns. The record is limited to a particular moment and set of pools; repeated RPC out-of-gas errors are also shown, which may impair quote collection. Slippage, transaction execution risk, and broader testing are not discussed.
Key ideas
- The monitor compares buy and sell quotes across pools on the same chain.
- It evaluates a stated trade size and subtracts estimated gas costs from gross profit.
- It includes a comparison against centralized exchange prices.
- All opportunities in the displayed snapshot have negative net profit and no trade indication.
- Repeated RPC out-of-gas errors may affect data collection reliability.
