Spartan Protocol
Summary
Spartan Protocol is a BSC-based decentralized liquidity protocol offering token swapping and synthetic asset generation via a liquidity-sensitive AMM. On May 2, 2021, a flash loan exploit targeting a flaw in the protocol's liquidity share calculation resulted in the loss of approximately $30 million in user funds, none of which were verifiably recovered. The protocol relaunched as V2 in October 2021 but has seen drastically reduced activity and a near-total collapse in token value.
