The Wormhole exploit tested cross-chain bridge recovery
In February 2022 Wormhole disclosed a vulnerability that allowed unauthorized minting of wrapped assets; the incident was addressed after intervention by the project and supporters.
The event showed how a bridge’s message-verification layer can become a single high-value attack surface.
It intensified scrutiny of validator signatures, cross-chain message authenticity and emergency recovery powers.
Bridge users should understand who can halt, patch or recapitalize a system during an incident.
