Mantle Joins $7.2 Billion Exodus From LayerZero to Chainlink CCIP

More than $7.2 billion in cross chain and wrapped assets have moved from LayerZero to Chainlink’s Cross Chain Interoperability Protocol since May, with Mantle now becoming the latest project to make the switch for its high-value token transfers.

Mantle Shifts Super Portal to Chainlink Standard

Mantle is migrating its Super Portal, a bridge it built with Bybit, from LayerZero’s Omnichain Fungible Token standard to Chainlink’s Cross-Chain Token standard. The portal handles MNT transfers between Ethereum and Solana, with more blockchain support planned. MNT itself holds more than $2.5 billion in locked value, pushing total announced migrations from LayerZero to Chainlink CCIP past $7.24 billion. The Super Portal will pause during the switch, scheduled for July 9 through July 15, though existing MNT holdings on Ethereum, Solana, Byreal and Bybit won’t be affected.

Bridge Security Concerns Drive the Trend

Cross-chain bridges have become a major weak point in crypto, since a single flaw can expose hundreds of millions in user funds. The migration wave picked up after a $292 million exploit hit Kelp’s LayerZero-powered bridge earlier this year, prompting closer scrutiny of similar setups. Kelp later moved over $1.5 billion in assets to Chainlink CCIP. Other projects have followed suit: Solv Protocol shifted $700 million in tokenized bitcoin, Re moved $475 million, Kraken transferred $330 million in wrapped assets, Lombard migrated more than $1 billion, Virtuals Protocol moved $700 million and Yuzu Money shifted $54.5 million.

Mantle Cites Control and Security

Mantle advisor Emily Bao said infrastructure carrying tokenized assets across chains “cannot be an afterthought” as the sector scales up. Under the new CCT standard, Chainlink’s decentralized oracle network will secure MNT transfers, while Mantle gains direct control over token pools and transfer settings as it expands to new chains.
