This trend gained momentum following a security incident earlier this year, where a LayerZero-powered bridge was exploited in a hack of KelpDAO's rsETH, resulting in a $292 million loss. That event prompted widespread reassessment of cross-chain security standards.

Mantle, which developed its Super Portal in collaboration with the crypto exchange Bybit, stated it selected Chainlink CCIP after a review to meet institutional-grade security requirements. The new infrastructure utilizes Chainlink's decentralized oracle network, secured by independent node operators, and includes built-in rate limits. The migration...
