How to Serve Your Sandwich? MEV Attacks in Private L2 Mempools
Krzysztof Gogol, Manvir Schneider, Jan Gorzny +1
We study the feasibility, profitability, and prevalence of sandwich attacks on Ethereum rollups with private mempools. First, we extend a formal model of optimal front- and back-ru…
When Priority Fails: Revert-Based MEV on Fast-Finality Rollups
Krzysztof Gogol, Manvir Schneider, Claudio Tessone
We study the economics of transaction reverts on Ethereum rollups and show that they are not accidental failures but equilibrium outcomes of MEV strategies. Using execution traces…
Scaling DeFi with ZK Rollups: Design, Deployment, and Evaluation of a Real-Time Proof-of-Concept
Krzysztof Gogol, Szczepan Gurgul, Faizan Nehal Siddiqui +2
Ethereum's scalability limitations pose significant challenges for the adoption of decentralized applications (dApps). Zero-Knowledge Rollups (ZK Rollups) present a promising solut…
Cross-Rollup MEV: Non-Atomic Arbitrage Across L2 Blockchains
Krzysztof Gogol, Johnnatan Messias, Deborah Miori +2
This study quantifies the potential non-atomic MEV on Layer-2 (L2) blockchains by measuring the arbitrage opportunities between cross-rollup and DEX-CEX. Over recent years, we obse…
SoK: Decentralized Finance (DeFi) -- Fundamentals, Taxonomy and Risks
Krzysztof Gogol, Christian Killer, Malte Schlosser +3
Decentralized Finance (DeFi) refers to financial services that are not necessarily related to crypto-currencies. By employing blockchain for security and integrity, DeFi creates ne…
SoK: Liquid Staking Tokens (LSTs) and Emerging Trends in Restaking
Krzysztof Gogol, Yaron Velner, Benjamin Kraner +1
Liquid staking and restaking represent recent innovations in Decentralized Finance (DeFi) that garnered user interest and capital. Liquid Staking Tokens (LSTs), tokenized represent…
Quantifying Arbitrage in Automated Market Makers: An Empirical Study of Ethereum ZK Rollups
Krzysztof Gogol, Johnnatan Messias, Deborah Miori +2
Arbitrage can arise from the simultaneous purchase and sale of the same asset in different markets in order to profit from a difference in its price. This work systematically revie…
Liquid Staking Tokens in Automated Market Makers
Krzysztof Gogol, Robin Fritsch, Malte Schlosser +3
This paper studies liquid staking tokens (LSTs) on automated market makers (AMMs), both theoretically and empirically. LSTs are tokenized representations of staked assets on proof-…
Cross-border Exchange of CBDCs using Layer-2 Blockchain
Krzysztof Gogol, Johnnatan Messias, Malte Schlosser +2
This paper proposes a novel multi-layer blockchain architecture for the cross-border trading of CBDCs. The permissioned layer-2, by relying on the public consensus of the underlyin…
Empirical and Theoretical Analysis of Liquid Staking Protocols
Krzysztof Gogol, Benjamin Kraner, Malte Schlosser +3
Liquid staking has become the largest category of decentralized finance protocols in terms of total value locked. However, few studies exist on its implementation designs or underl…
