Bytecode-Level Detection of Ethereum Upgradeability Proxy Contracts

UPC Sentinel detects active upgradeability proxy contracts (UPCs) directly from Ethereum smart-contract bytecode using a three-layer pipeline: dynamic analysis to confirm a contract is an active proxy, combined static+dynamic analysis to decide whether it is upgradeable, and pattern classification. Working on bytecode reaches closed-source contracts, and multi-level dynamic dependency analysis captures transitive dependencies missed by prior tools.

UPC Sentinel: An Accurate Approach for Detecting Upgradeability Proxy Contracts in Ethereum

UPC Sentinel is a three-layer algorithm combining static and dynamic analysis of Ethereum smart-contract bytecode to detect active upgradeability proxy contracts (UPCs) — proxies that delegate calls …
