Gas & Execution Optimization for Early DEX Arbitrage
- 10 Jan 2026
Introduction
Fast execution and gas optimization are critical for capturing alpha on newly listed DEX pairs. Even if you identify a lucrative opportunity, poor transaction timing or high gas fees can erase potential profits. This guide focuses on practical techniques to optimize execution while minimizing risk.
This article builds on the foundation laid in Spot New DEX Pairs Before Everyone Else and complements other strategies in the Alpha & Insider cluster:
Step 1: Understanding Gas Fees
- Gas fees determine the priority of your transaction in the network.
- Monitor current network congestion using tools like Etherscan Gas Tracker or custom RPC dashboards.
- Use dynamic gas settings: higher fees for high-alpha trades, lower for monitoring or exploratory trades.

Step 2: Mempool Monitoring
- Mempools show pending transactions before they hit the blockchain.
- Track front-running and sandwich attack patterns to avoid being outpaced.
- Tools like Flashbots, MEV-Inspect, or custom monitoring scripts help you detect profitable windows.

Step 3: Transaction Bundling & Priority
- For multiple arbitrage trades, bundle transactions to reduce gas overhead and maintain execution order.
- Use private RPC nodes or Flashbots bundles for high-value trades to bypass public mempool exposure.
- Always calculate expected ROI vs gas cost to avoid negative outcomes.
Step 4: Execution Strategies
- Manual Execution: Best for small trades or testing new strategies.
- Automated Scripts: Use bots for speed-critical trades, but incorporate rate limits and safety checks.
- Hybrid Approach: Monitor mempool manually and trigger bot scripts for precision execution.
This complements Spot New DEX Pairs Before Everyone Else by turning opportunity spotting into actionable trades.
Step 5: Risk Management & Safety
- Never overallocate capital in low-liquidity pools; slippage can wipe gains.
- Avoid suspicious contracts or new tokens with high deployer concentration.
- Diversify execution across multiple pairs to reduce exposure.
