Volo Intercepts $2.1M WBTC Bridge, Freezes Funds After $3.5M Sui Exploit

Volo Protocol froze stolen funds—including a blocked 19.6 WBTC ($2.1M) bridge attempt and $500,000 secured within 30 minutes—after an April 21, 2026, $3.5M exploit via admin key compromise on Sui. The attack drained WBTC ($2.1M), XAUm ($0.9M), and USDC ($0.5M) from three vaults, but $28M TVL elsewhere remains safe; Volo will absorb losses without passing to users. Impact contained: SUI up 2.7% at $0.97 despite 3.4% network TVL drop, amid April's $600M DeFi breaches pressuring key management and crypto sentiment.
