Volo Protocol
Summary
Volo Protocol is a liquid staking and DeFi vaults platform built on the Sui blockchain, offering voloSUI (vSUI) as a liquid staking token and multi-asset yield vaults. In January 2024, it was acquired by NAVI Protocol, a leading Sui lending protocol. On April 22, 2026, Volo suffered a $3.5 million exploit targeting three isolated vaults holding WBTC, XAUm, and USDC; the team pledged to absorb all user losses and approximately $500,000 was frozen on-chain, while the root cause — attributed by security researchers to a compromised privileged operator key rather than a smart contract flaw — remained under investigation at time of writing.
