Cross-chain bridges like LayerZero and Wormhole have seen a surge in transaction volume, but frequent security vulnerabilities are raising concerns. On X, users are discussing how new cross-chain protocols can enhance both security and interoperability. While cross-chain bridges enable assets to flow seamlessly between different blockchains, their centralized nature makes them vulnerable to attacks. The rise in hacks has prompted a demand for solutions that improve safety while maintaining the ability to interact with multiple chains. New protocols are focusing on decentralization, encryption, and consensus mechanisms to address these issues, offering a promising future for cross-chain interactions without compromising on security.
