Looking for Anomalies in Cross-Chain Bridges

In recent years, there has been a growing adoption of blockchain interoperability solutions and cross-chain protocols [1] , [5] . The most popular are cross-chain bridges or, simply, bridges. Bridges connect decentralized applications across various blockchains, supporting the transfer and exchange of assets between blockchains. Cross-chain bridges now have tens of billions of total value locked (TVL). However, this growth has also led to the theft of billions in cross-chain protocols [1] . Not even extensively audited bridges are immune to vulnerabilities [7] .
