No Place to Hide: An Analysis on Protected Order Flow Sandwich Attacks
Lioba Heimbach, Ozan Solmaz, Burak Öz +1
Front-running has long plagued Ethereum's public mempool, earning it the nickname of a "dark forest", where predators lurk for profitable transactions. In response, Ethereum and ot…
IntentFuzz: A Protocol-Aware Fuzzer for Automated Invariant Violation Detection in Intent-Based Cross-Chain Bridges
André Augusto, Christof Ferreira Torres, André Vasconcelos +1
Cross-chain bridges move value between blockchains. Intent-based bridges are a variant where a solver fulfills a user's declared outcome and an off-chain settlement layer later rec…
There Will Be Spam: Characterizing State-Invariant Transactions and Speculative MEV
Vabuk Pahari, Johnnatan Messias, Christof Ferreira Torres
Blockchains rely on transparency and immutability to ensure trust, but these guarantees come at the cost of an ever-growing ledger that increasingly threatens decentralization by m…
Signals and Spoils: Speculative Oracle Extractable Value in the Era of Cross-Chain Interoperability
Hasret Ozan Sevim, Christof Ferreira Torres
A new form of Maximal Extractable Value (MEV), termed speculative MEV, has emerged across Layer-2 blockchains. Unlike Ethereum mainnet, many Layer-2 systems lack a public mempool,…
Exploiting Liquidity Exhaustion Attacks in Intent-Based Cross-Chain Bridges
André Augusto, Christof Ferreira Torres, André Vasconcelos +1
Intent-based cross-chain bridges have emerged as an alternative to traditional interoperability protocols by allowing off-chain entities (\emph{solvers}) to immediately fulfill use…
The Express Lane to Spam and Centralization: An Empirical Analysis of Arbitrum's Timeboost
Johnnatan Messias, Christof Ferreira Torres
DeFi applications are vulnerable to MEV, where specialized actors profit by reordering or inserting transactions. To mitigate latency races and internalize MEV revenue, Arbitrum in…
Cross-Chain Arbitrage: The Next Frontier of MEV in Decentralized Finance
Burak Öz, Christof Ferreira Torres, Christoph Schlegel +4
Decentralized finance (DeFi) markets spread across Layer-1 (L1) and Layer-2 (L2) blockchains rely on arbitrage to keep prices aligned. Today most price gaps are closed against cent…
Rolling in the Shadows: Analyzing the Extraction of MEV Across Layer-2 Rollups
Christof Ferreira Torres, Albin Mamuti, Ben Weintraub +2
The emergence of decentralized finance has transformed asset trading on the blockchain, making traditional financial instruments more accessible while also introducing a series of…
