Wasabi Protocol Hack: $4.5M Loss and DeFi Lessons

Wasabi Protocol suffered a $4.55 million breach after attackers seized the private key for wasabideployer.eth and used a UUPS upgrade to grant themselves ADMIN_ROLE, replacing perp-vault and Long Pool code on Ethereum and Base. Funds from multiple vaults (wWETH, sUSDC, wBITCOIN, wPEPE on ETH; sUSDC, wWETH, sBTC, sVIRTUAL, sAERO, sBRETT on Base) were drained and users were urged to revoke LP approvals. The incident underscores ongoing single-key vulnerabilities across DeFi; cumulative losses in 2026 have topped $770M and recent high-profile hacks (eg. DRIFT) have prompted delistings and trust erosion. Market-wise, the piece notes ETH trading near $2,307 with a neutral RSI but warns that DeFi hacks are pressuring a sideways trend and could boost futures volatility — reinforcing bearish sentiment and accelerating demand for multisig/timelock governance.
