Spartan Protocol
Summary
Spartan Protocol is a decentralized liquidity and synthetic-asset protocol that launched on Binance Smart Chain (BSC) in 2020 and was operated by a fully anonymous, community-driven team. On May 2, 2021, a critical vulnerability in the protocol's liquidity-share calculation logic was exploited via flash loan, resulting in approximately $30 million in stolen funds — ranking it among the largest DeFi exploits of that era. The protocol attempted a v2 rebuild with re-audited contracts but has since fallen to near-zero TVL and market cap, with no meaningful development activity recorded after 2024.
