More to Extract: Discovering MEV by Token Contract Analysis
Jiaqi Chen, Yuzhe Tang, Yue Duan
This paper tackles the discovery of tMEV, that is, the Maximal Extractable Value on blockchains that arises from Token smart contracts. This scope differs from the existing MEV-dis…
Understanding the Security Risks of Decentralized Exchanges by Uncovering Unfair Trades in the Wild
Jiaqi Chen, Yibo Wang, Yuxuan Zhou +4
DEX, or decentralized exchange, is a prominent class of decentralized finance (DeFi) applications on blockchains, attracting a total locked value worth tens of billions of USD toda…
Efficiently Hardening SGX Enclaves against Memory Access Pattern Attacks via Dynamic Program Partitioning
Yuzhe Tang, Kai Li, Yibo Wang +2
Intel SGX is known to be vulnerable to a class of practical attacks exploiting memory access pattern side-channels, notably page-fault attacks and cache timing attacks. A promising…
TopoShot: Uncovering Ethereum's Network Topology Leveraging Replacement Transactions
Kai Li, Yuzhe Tang, Jiaqi Chen +2
Ethereum relies on a peer-to-peer overlay network to propagate information. The knowledge of Ethereum network topology holds the key to understanding Ethereum's security, availabil…
iBatch: Saving Ethereum Fees via Secure and Cost-Effective Batching of Smart-Contract Invocations
Yibo Wang, Kai Li, Yuzhe Tang +4
This paper presents iBatch, a middleware system running on top of an operational Ethereum network to enable secure batching of smart-contract invocations against an untrusted relay…
