Mantle is moving its Super Portal from LayerZero to Chainlink CCIP for high-value cross-chain MNT transfers. The migration adds another major project to a broader shift away from LayerZero bridge infrastructure since May. It also places Chainlink’s Cross-Chain Token standard at the center of a growing wrapped-asset migration wave.
Mantle keeps MNT transfers unaffected during migration
Mantle said the Super Portal will move from LayerZero’s Omnichain Fungible Token standard to Chainlink’s Cross-Chain Token standard. The portal was co-developed with Bybit and supports MNT transfers between Ethereum and Solana. The project plans support for more blockchain networks after the transition ends.
The migration affects MNT, the native token of the network, which holds more than $2.5 billion in value locked. Mantle said existing MNT on Ethereum and Solana will remain unaffected during the process. Activity involving MNT on Byreal and Bybit will also continue without disruption.
The Super Portal will pause during the migration window from July 9 to July 15. The suspension allows the project to complete the technical change without affecting existing token balances. The team framed the move as an infrastructure update for cross-chain token movement.
CCIP migration follows bridge security scrutiny
More than $7.2 billion in cross-chain and wrapped assets have moved from LayerZero to Chainlink CCIP since May. Mantle became the latest project to replace LayerZero for transfers involving high-value token assets. The move lifted announced migrations to Chainlink CCIP above $7.24 billion.
The shift followed the $292 million Kelp bridge exploit earlier this year. That incident increased attention on bridge configurations that used LayerZero-powered systems. Kelp later said it would move more than $1.5 billion in assets to Chainlink CCIP.
Several other projects also announced migrations after the exploit. Solv Protocol moved $700 million in tokenized bitcoin, and Re shifted $475 million. Kraken, Lombard, Virtuals Protocol, and Yuzu Money also transferred wrapped or cross-chain assets.
New setup gives direct pool control
Under the new structure, Chainlink CCIP will secure MNT transfers through its decentralized oracle network. Mantle said the CCT standard gives it direct control over token pools and transfer settings. That control supports future expansion across more networks and tokenized asset markets.
LayerZero and Chainlink CCIP both support transfers between separate blockchain networks. These systems help users move tokens across markets that operate on different chains. However, bridge infrastructure remains a major security area for crypto projects.
“As tokenized financial assets move from concept to scale, the infrastructure that carries them across chains cannot be an afterthought,” Emily Bao said.
Bao serves as a key advisor at Mantle and commented in the project’s statement. Mantle now moves ahead with the Super Portal migration while keeping existing MNT activity unaffected.
