Summary

DFX Finance is a decentralized foreign exchange protocol optimized for trading fiat-backed stablecoins such as CADC, EURS, and XSGD, backed by investors including Polychain Capital. On November 10, 2022, the V2 smart contracts were exploited via a reentrancy vulnerability in the flash loan function, resulting in approximately $7.5 million in total losses split between a primary attacker (~$4.3M) and an MEV front-running bot (~$3.2M). The stolen funds were funneled into Tornado Cash; the protocol subsequently paused all contracts, launched a DFX-token reimbursement plan, and later released V3, but TVL remains near zero as of 2024.
