Mantle Moves Super Portal to Chainlink as CCIP Migration Total Tops $7.2B

Mantle is migrating its Super Portal, co-developed with Bybit, from LayerZero’s Omnichain Fungible Token standard to Chainlink’s Cross-Chain Token standard. The move makes Mantle the latest project to shift high-value token-transfer infrastructure to Chainlink’s Cross-Chain Interoperability Protocol, with announced migrations from LayerZero now above $7.24 billion, according to CoinDesk.

The development matters because cross-chain bridges remain a major security concern in crypto. These systems let assets move between blockchains, but failures can expose large amounts of user funds, making the choice of transfer infrastructure important for protocols, exchanges and tokenized asset issuers.

Mantle said the migration covers MNT, the native token of its network, and the Super Portal currently enables transfers between Ethereum and Solana. The project plans to add support for more blockchain networks, while Chainlink CCIP will secure MNT transfers through its decentralized oracle network.

CoinDesk reported that the latest shift follows increased scrutiny of LayerZero-powered bridge configurations after a $292 million Kelp bridge exploit earlier this year. Kelp later said it would move more than $1.5 billion in assets to Chainlink CCIP, while other migrations have included Solv Protocol, Re, Kraken’s tokenized assets, Lombard, Virtuals Protocol and Yuzu Money.

Mantle said the Super Portal will be suspended during the migration, scheduled for July 9 through July 15. Existing MNT on Ethereum and Solana, as well as MNT activity on Byreal and Bybit, are expected to remain unaffected during the process.
