Mantle is moving its Super Portal, developed with Bybit, to Chainlink’s Cross-Chain Interoperability Protocol (CCIP), replacing LayerZero as the cross-chain infrastructure securing transfers of the MNT token across Mantle’s more than $2.5 billion ecosystem.

The company said the migration strengthens security through Chainlink’s decentralized oracle network and institutional-grade safeguards while giving Mantle direct control over its cross-chain token infrastructure under the Cross-Chain Token standard. The Super Portal will be suspended temporarily during the transition, with no action required from users.

Emily Bao, a key advisor at Mantle, said the decision would provide institutional-grade security for MNT transfers as tokenized assets gain wider adoption.

“As tokenized financial assets move from concept to scale, the infrastructure that carries them across chains cannot be an afterthought,” Bao noted.

Mantle said the new infrastructure will enable MNT to expand across more blockchain networks as demand grows for cross-chain movement of tokenized assets.

Chainlink’s CCIP has gained momentum after several crypto projects such as Virtuals and Lombard migrated away from LayerZero in the wake of a high-profile DeFi exploit. The transition has resulted in more than $7.2 billion worth of cross-chain and wrapped assets moving onto Chainlink’s network since May.

“We’re continuing to see an industry trend of leading protocols upgrading their cross-chain infrastructure to meet the requirements of institutional adoption,” Johann Eid, Chief Business Officer at Chainlink Labs, stated. “Mantle’s migration to Chainlink CCIP reflects the growing recognition that secure-by-default infrastructure is critical for any cross-chain deployment to succeed at scale.”
