Summary

Zabu Finance was an Avalanche-based yield farming protocol that suffered a $3.2 million flash loan exploit on September 12, 2021, marking what was widely described as the first major DeFi hack on the Avalanche blockchain. The vulnerability — a known deflationary token accounting flaw that had already been exploited on Polygon two months prior — drained the protocol's SPORE staking pool and caused the ZABU token to collapse from approximately $0.004 to near-zero. The protocol attempted a v2 token relaunch but has since gone effectively dormant, with a TVL of approximately $5,000 and a website SSL certificate that expired in August 2022.
