To be presented at @TheWebConf of @TheOfficialACM arxiv.org/abs/2601.08641 Thanks to @Morris56912799 from @uclfincomp @UCLEngineering @ucl, Yebo Feng & Prof Yang Liu from @NTUsg for the collab, and to @Exponential_Sci & @UKCBT_org 's support through @Ripple 's UBRI program
In meme coin trading, sneaky bots (often run by scammers) fake hype, buy cheap early, lure people into copying them, then dump high, leaving copiers wrecked. Paper exposes these cheating bots & builds an AI system to detect and avoid them. Partially funded by @Ripple UBRI. 🔗👇

Proud of my PhD student to become a Prof, especially Kaihua, who already has helped *selflessly* so many of my other students in a supervisory capacity. Apply to work with Kaihua. He goes deep and doesn't shy away from details where others fold. Going to 80% is easy. Going to 100% is what matters. He'll help you realize your potential in doing so.

How are @GyroStable's new Dynamic Pools doing? Here's ETH/USDC on Base measured by market making PnL (TVL-adjusted markouts). Noticeably the best performance for this pair at the pool level. And it serves passive LPs. Let's walk through what this means 👇 Why markouts? Markouts compare the execution prices LPs receive in a liquidity pool against the ‘true’ prices on CEXs. - Positive markouts means LPs are making a trading profit. - Negative markouts means LPs are leaking value to arbitrageurs. Other components to LP profitability LPs can also earn a return from 'volatility harvesting' if prices mean revert / wiggle around for a period of time. You can think of this in a simple way as effectively buying low and selling high over time (if the pool can achieve this) *while* prices wiggle back and forth. If a pool captures volatility harvesting, it can add profitability on top of markouts. - A pool with positive markouts and volatility harvesting will do even better. - If a pool has large negative markouts, it will be very hard to overcome this even with volatility harvesting. The only pools today that really 'guarantee' volatility harvesting are pools that preserve the 'constant function' property of static AMMs. And then only while prices wiggle back and forth. Pools in which LPs constantly shift positions (e.g., most concentrated liquidity) give up this property and lock in IL at each shift. In which case, LPs must shift liquidity in sophisticated ways if they want to achieve volatility harvesting or conceivably lose money on this component too. Dynamic E-CLPs Gyroscope's Dynamic Pools are designed to capture volatility harvesting by preserving the 'constant function' property in most settings (liquidity updates are designed to be rare). They're designed to move with the market but settle into regions in which they have a shot at volatility harvesting. Which means that Gyro LPs benefit from good positioning both on the empirical markouts performance above and volatility harvesting.

Highly recommended. Learn about the research that we did with @Campa_91 , @JiahuaJavaXu and @PaoloTasca about the effects in the costs of liquidity and Total Value Locked for USDC and USDT in @Uniswap before, during and after the collapse of Silicon Valley Bank
It’s a wrap on our recent #webinar! 👩‍💻Missed it? Watch it here: youtu.be/GLW4ezGfbhg The webinar on How Stable Are Stablecoins? featuring presentations by our Research Fellow Walter J. Hernandez and Carlo Campajola our Head of Tokenomics & Lecturer in Artificial Intelligence and Financial Analytics @UCL Here are the highlights: 1. Carlo dove into #stablecoins, explaining their pivotal role in the #crypto ecosystem. 2. Carlo covered types, backing systems, benefits, and use cases of stablecoins, highlighting their rise post-#DeFi summer 2020-2021. He also explained the Terra-Luna crash to illustrate the risks of algorithmic stablecoins. 3. Walter presented their research on “The effects of transparency on stablecoin liquidity during the collapse of the Silicon Valley Bank,” conducted with @JiahuaJavaXu, @Paolotasca, and Carlo. 📃 In this study they analysed USD-USDT liquidity pools on DEXs during the crisis to examine transparency effects. Want to know more about their findings? Check out the report here -> arxiv.org/abs/2407.11716 🙌 A big thanks to all attendees and our researchers for this enriching dialogue! 🤓 #FinTech #Blockchain

1B USD of total volume has now been settled through Gyroscope. And growth is turning up. Volumes are up 66% month-over-month. And Rehype pools are scaling into the most capital efficient pool type in DeFi.

The number of people holding more than $100 GYD has increased 500% in the last half of March. Most heard: people are still surprised by how liquid GYD is. @GyroStable gives you extremely efficient stablecoin liquidity while getting more resilient mechanisms basically for free.
