Mantle joins wave of protocols migrating from LayerZero OFT to Chainlink CCIP standard
Mantle is migrating its Super Portal from LayerZero’s OFT standard to Chainlink’s CCT standard for cross-chain MNT token transfers, joining a broader exodus that has seen $7.2 billion in assets move to Chainlink CCIP since May 2026.
The migration window runs from July 9 to July 15, 2026. Mantle’s Super Portal, co-developed with exchange Bybit, currently locks $2.5 billion in value and enables MNT transfers between Ethereum and Solana, with additional blockchain networks planned.
The shift reflects growing concerns over cross-chain bridge security. A $292 million exploit of the Kelp bridge earlier in 2026 intensified scrutiny of LayerZero-powered configurations. Kelp itself has since migrated $1.5 billion to Chainlink CCIP. Other major protocols have followed: Lombard moved over $1 billion, Solv Protocol transferred $700 million in tokenized bitcoin, Virtuals Protocol moved $700 million, and Re migrated $475 million. Kraken transferred $330 million in wrapped assets, and Yuzu Money moved $54.5 million.
Under the new setup, Chainlink CCIP will secure MNT transfers using its decentralized oracle network. The migration grants Mantle direct control over token pools and transfer settings under the CCT standard, replacing the previous OFT model.
Emily Bao, key advisor at Mantle, stated: “As tokenized financial assets move from concept to scale, the infrastructure that carries them across chains cannot be an afterthought.”
Bridges between blockchains are recognized as one of crypto’s largest security risks, with single failures exposing hundreds of millions in user assets. Both LayerZero and Chainlink CCIP enable token holders to move assets between blockchains, but the migration wave underscores the market’s preference for Chainlink’s infrastructure at scale.
