Mantle Fortifies Cross-Chain Security with Chainlink CCIP Migration
Event summary
- Mantle migrated its Super Portal from LayerZero to Chainlink CCIP, enhancing security for cross-chain transfers of its $2.5B+ MNT token.
- The migration, occurring July 9–15, 2026, temporarily suspends the Super Portal but requires no user action.
- Chainlink CCIP offers institutional-grade security features, including SOC 2 Type 2 compliance and decentralized node infrastructure.
- Mantle adopted the Cross-Chain Token (CCT) standard, providing full autonomy over its smart contracts and cross-chain token pool.
The big picture
Mantle's migration reflects a broader industry shift towards secure cross-chain infrastructure as tokenized financial assets scale. With billions lost to exploits, the move aligns with institutional demands for enterprise-grade security standards. This upgrade positions Mantle as a key player in connecting traditional finance with on-chain liquidity.
