Cross-chain bridges represent one of the most vulnerable attack surfaces in the cryptocurrency ecosystem, as demonstrated by the Wanchain bridge incident where 515 million NIGHT tokens were moved from a compromised bridge contract to the Cardano ecosystem, causing a 30-50% price drop. This incident highlights that bridge vulnerabilities can be localized to specific bridge infrastructure rather than affecting the entire network, and that formal methods and peer review significantly reduce potential attack vectors in decentralized systems.
