Blockchain bridges have experienced significant security breaches, resulting in over $2.8 billion in stolen assets by mid-2025. These bridges, essential for connecting different blockchains, are vulnerable due to weak on-chain checks, unsafe off-chain verification, token handling errors, and setup mistakes. Hackers have exploited these vulnerabilities to forge signatures, bypass security checks, and utilize infinite approvals. The report emphasizes the need for improved bridge design and increased user awareness to enhance security in blockchain interoperability.
