衡量链上订单流拍卖的价格改善
文章 arXiv papers · 作者: Brad Bachu et al.
总结
本文提出一种衡量链上订单流拍卖(OFA)带来价格改善的框架。文章介绍如何将执行收益归因于可调系统输入,包括路由质量、燃料费使用和优先费设置,旨在将拍卖效应与其他改善成交价格的来源区分开来。
在包括1Inch和Uniswap在内的以太坊交易界面上应用该方法后,分析报告称其样本中的平均收益为4–5个基点,且具有统计显著性。研究将价格改善主要归因于大额兑换可获得的额外流动性。摘录未提供样本量、期间、交易明细或统计检验细节,因此应将报告的平均值视为仅适用于所研究界面和数据的结果,而非普遍保证。
核心观点
- 该框架通过衡量价格改善来评估链上订单流拍卖。
- 框架将执行结果归因于路由、燃料费优化和优先费选择。
- 样本中,所研究的交易界面平均带来4–5个基点的改善。
- 分析认为,收益主要来自大额兑换获得的额外流动性。

# Quantifying Price Improvement in Order Flow Auctions # Quantifying Price Improvement in Order Flow Auctions 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.
