Recently exploring layer 2 solutions on Ethereum, researchers investigated how different trade order policies affect arbitrage opportunities. The study, authored by academics including Akaki Mamageishvili, Offchain Labs’ Ed Felten and others, examined the potential profitability of arbitrage strategies when time advantages are auctioned for inclusion of transactions in layer 2 networks, according to Offchain Labs.
Research Methodology
This study outlines three scenarios to evaluate the impact of trading order policies on arbitrage.
- First come first serve (FCFS): This method involves capturing arbitrage opportunities as they arise, without any premium for including faster trades. Participants invest in latency infrastructure to speed up transaction sequences.
- Gas Priority Auction (PGA): Here, transactions are prioritized based on the monetary tip provided to the block builder, incentivizing traders to pay more for processing initial transactions within a block.
- FCFS with time advantage: In this scenario, users bid on priority trade orders using dynamic programming to optimize when trades are executed for maximum profit.
Researchers conducted simulations to determine the potential profits under these market conditions.
Research Results
Studies have shown that the choice of trading order policy has a significant impact on arbitrage profits. FCFS using the Time Advantage method has been shown to be the most profitable approach, especially on highly volatile trading pairs such as ETH-USDT. Simulation results show that this strategy generates 47.7% more revenue than PGA and 86.77% more than traditional FCFS.
Implications for MEV extraction
This study further highlights implications for maximum extractable value (MEV) operations. The design of the trading sequence mechanism affects profit distribution, and time-advantaged arbitrageurs are advised to delay trades within the time window to maximize profits. Additionally, Automated Market Maker (AMM) pools can potentially reclaim MEV by adjusting fees and limiting trading frequency for arbitrageurs.
The paper also points out that although the negative autocorrelation of price movements may favor an immediate FCFS strategy, overall, FCFS with its time advantage is more profitable than PGA, especially in volatile market conditions.
These results provide important insights for traders and developers in optimizing trading order policies to improve arbitrage profitability on Ethereum’s layer 2 network.
