量化订单流拍卖中的价格改善

Quantifying Price Improvement in Order Flow Auctions

Brad Bachu, Xin Wan, Ciamac C. Moallemi

AI总结:

本文提出一个评估链上订单流拍卖的框架,通过开源工具将价格改善归因于可修改输入,应用于1Inch和Uniswap等界面,发现拍卖增强型界面平均改善4-5个基点,来源为大额交换的额外流动性。

摘要:

这项工作引入了一个用于评估链上订单流拍卖(OFAs)的框架,重点强调价格改善这一指标。利用一组开源工具,我们的方法系统地将价格改善归因于系统的特定可修改输入,如路由效率、燃气优化和优先费设置。当应用于领先的基于以太坊的交易界面(如1Inch和Uniswap)时,结果显示,拍卖增强型界面可以在交易结果上提供统计显著的改善,在我们的样本中平均为4-5个基点。我们进一步确定了此类价格改善的来源是为大额交换增加的流动性。这项研究为基于区块链的交易平台的未来创新奠定了基础。

英文摘要:

This work introduces a framework for evaluating onchain order flow auctions (OFAs), emphasizing the metric of price improvement. Utilizing a set of open-source tools, our methodology systematically attributes price improvements to specific modifiable inputs of the system such as routing efficiency, gas optimization, and priority fee settings. When applied to leading Ethereum-based trading interfaces such as 1Inch and Uniswap, the results reveal that auction-enhanced interfaces can provide statistically significant improvements in trading outcomes, averaging 4-5 basis points in our sample. We further identify the sources of such price improvements to be added liquidity for large swaps. This research lays a foundation for future innovations in blockchain based trading platforms.
