Cross-Chain Vulnerabilities

Architecture

Cross-chain vulnerabilities arise from the inherent complexity of interoperability protocols designed to facilitate asset transfers between disparate blockchain networks. These systems often rely on a bridge architecture, where assets are locked on one chain and mirrored on another, creating a single point of failure if the validation mechanism or smart contract logic is compromised. The security model of a cross-chain bridge is only as strong as its weakest link, often involving external validators or multi-signature schemes.
