FlashSyn: Flash Loan Attack Synthesis via Counter Example Driven Approximation
Zhiyang Chen, Sidi Mohamed Beillahi, Fan Long
Abstract
In decentralized finance (DeFi), lenders can offer flash loans to borrowers, i.e., loans that are only valid within a blockchain transaction and must be repaid with fees by the end of that transaction. Unlike normal loans, flash loans allow borrowers to borrow large assets without upfront collaterals deposits. Malicious adversaries use flash loans to gather large assets to exploit vulnerable DeFi protocols.
