Arbitrage Extractable Value with Anthony Lee Zhang | a16z crypto research talks

TL;DR

Impermanent loss in AMMs refers to the slippage that occurs when trading at prices worse than the centralized exchange prices, resulting in losses for liquidity providers.

Transcript

for today very happy to introduce Anthony Lee Zack who committed you have had fun conversations with over the week from University of Chicago he's a professor in the business school talking about Arbitrage extractable value all right so thanks a lot very happy to be here I'll get started I have to apologize uh you saw this paper before a week ago a...

Key Insights

• 🌸 Impermanent loss in AMMs is caused by trading at prices worse than the centralized exchange prices, resulting in losses for liquidity providers.
• 🌸 "Arbitrage extractable value" is a measure of impermanent loss and represents the profits that arbitragers can extract from the AMM.
• 🧑‍🏭 Impermanent loss can be calculated using formulas that consider factors such as the AMM invariant and price volatility.
• 🌸 Quantifying impermanent loss helps in assessing the risks and rewards of providing liquidity in AMMs and making informed decisions.
• 🫵 The concept of impermanent loss in AMMs is similar to sniping discrepancies between different exchange prices and can be viewed as a form of convergence arbitrage.
• 🧑‍🏭 Impermanent loss is influenced by factors such as slippage, volatility, and the curvature of the AMM's invariant function.
• 🤱 There are limitations and assumptions in the analysis, such as ignoring fees, order flow, and gas fees.

Questions & Answers

Q: What is impermanent loss in the context of automated market makers?

Impermanent loss refers to the loss of liquidity provision through an AMM when trading at prices that are worse than the centralized exchange prices.

Q: How does the paper define "arbitrage extractable value"?

"Arbitrage extractable value" is defined as the slippage incurred by AMMs due to the difference between the AMM trading price and the centralized exchange price. It represents the profits that arbitragers can extract from the AMM.

Q: How is impermanent loss quantified in the paper?

The paper provides formulas to calculate impermanent loss, expressed as the percentage of portfolio value lost to arbitrage extractable value in a unit of time. The formulas vary depending on the specific AMM invariant being used.

Q: Why is it important to define and quantify impermanent loss?

Defining and quantifying impermanent loss helps to understand the impact and risks of providing liquidity in AMMs. It allows for better decision-making and risk management for liquidity providers.

Summary & Key Takeaways

• The paper discusses the concept of impermanent loss in automated market makers (AMMs) and aims to define and quantify it.

• Impermanent loss refers to the loss of liquidity provision through an AMM due to trading at prices worse than the centralized exchange prices.

• The paper presents the concept of "arbitrage extractable value" as a measure of impermanent loss and provides formulas to calculate it for different AMMs.
