Summary

Vesper Finance is an Ethereum-based DeFi yield aggregator co-founded by former Bitcoin Core developer Jeff Garzik that launched in early 2021 and briefly exceeded $1 billion in TVL. The protocol suffered a confirmed $3.37 million oracle manipulation exploit on Rari Fuse Pool #23 in November 2021, and was indirectly exposed to a May 2024 Sonne Finance exploit that required treasury remediation. Vesper remains operational as of 2025 with approximately $48–55 million TVL, though its native VSP token has lost over 99% of its all-time-high value.
