CertiK, a Web3 security firm, highlighted significant risks associated with cross-chain bridges and supply chain attacks at the DC Blockchain Summit. CBO Jason Jiang, referencing CertiK's "2025 Skynet Hack3D Report," identified smart contract vulnerabilities as a major attack surface, with cross-chain bridges being prime targets due to their concentrated liquidity. He noted that supply chain attacks in 2025 resulted in over $1.45 billion in damages from just two incidents, while phishing attacks were the most frequent. Jiang emphasized the need for regulatory frameworks that support responsible vulnerability disclosure and cross-industry collaboration. He also discussed with U.S. lawmakers the future of market structure, the adaptation of traditional banks to cryptocurrency, and enhancing consumer protection against fraud, stressing the importance of collaboration between technology providers and law enforcement.
