Clockwork Finance: Automated Analysis of Economic Security in Smart Contracts. (arXiv:2109.04347v2 [cs.CR] UPDATED)
cs.CR updates on arXiv.org arxiv.org
We introduce the Clockwork Finance Framework (CFF), a general purpose, formal
verification framework for mechanized reasoning about the economic security
properties of composed decentralized-finance (DeFi) smart contracts. CFF
features three key properties. It is contract complete, meaning that it can
model any smart contract platform and all its contracts--Turing complete or
otherwise. It does so with asymptotically constant model overhead. It is also
attack-exhaustive by construction, meaning that it can automatically and
mechanically extract all possible economic attacks on users' …
