Mantle's $2.5B MNT Token Exits LayerZero for Chainlink CCIP

Mantle, a project co-developed with Bybit, is migrating its Super Portal from LayerZero's Omnichain Fungible Token standard to Chainlink's Cross-Chain Interoperability Protocol (CCIP). This move follows the $292 million Kelp bridge exploit in which tokens and data were moved between blockchains. The migration pushes the total value of announced migrations from LayerZero to Chainlink CCIP above $7.24 billion since May.

Mantle's Super Portal enables transfers of its native token, MNT, between Ethereum and Solana. Support for additional blockchain networks is planned. During the migration, the portal will be suspended between July 9 and July 15. Existing MNT on Ethereum and Solana, along with MNT activity on Byreal and Bybit, will remain unaffected.

The migration reflects a broader reassessment of cross-chain infrastructure after a year in which bridge security has become one of the most important risk areas in crypto. Projects managing large pools of wrapped, tokenized, or cross-chain assets are reviewing their infrastructure due to increased scrutiny of LayerZero-powered bridge configurations.
