Unleash Protocol Breach: $3.9M Lost in Multisig Compromise, Governance Lapse Cited
December 30, 2025
Unleash Protocol suffered a security breach resulting in about $3.9 million in losses, likely due to a compromised multisig that enabled an unauthorized contract upgrade and withdrawals.
The unauthorized governance action originated within Unleash’s governance and permission framework, suggesting social engineering or other compromise bypassed normal checks.
Assets affected included WIP, USDC, WETH, stIP, and vIP, with all affected withdrawals occurring via the unauthorized upgrade rather than user-driven actions.
Preventive takeaways emphasize audits, regular multisig key rotation, and permission-management tools to minimize DeFi risks.
Unleash says it is conducting a root-cause investigation and will share updates through official channels, urging users to follow for safety guidance.
The breach did not affect the wider Story ecosystem but underscored governance as a critical risk in decentralized finance.
Security firms flagged suspicious withdrawals and activity, including moves to externally owned accounts and SafeProxyFactory-linked addresses.
Community reactions were mixed, with some labeling it a scam while others called for stronger governance security; the token did not show a significant price drop due to limited liquidity, but trust in the ecosystem could be affected.
Analysts attribute the incident to a governance failure at Unleash rather than a vulnerability in Story Protocol itself.
Unleash paused all protocol operations and engaged independent security experts; the impact is limited to Unleash contracts and administrative controls, not the broader Story Protocol infrastructure or validators.
There is no evidence of compromise to Story Protocol contracts, validators, or underlying infrastructure; emergency measures include pausing operations and advising users to avoid interacting with Unleash contracts until further notice.
Emergency steps included suspending platform operations, collaborating with forensics experts, and issuing guidance to avoid Unleash contracts pending official updates.
