Mantle shifts Super Portal to Chainlink CCIP in $2.5B upgrade

Mantle migrated its Super Portal from LayerZero to Chainlink CCIP, securing cross-chain transfers of MNT across its $2.5 billion ecosystem.

"As tokenized financial assets move from concept to scale, the infrastructure that carries them across chains cannot be an afterthought," said Emily Bao, Key Advisor at Mantle.

The Super Portal, co-developed with Bybit, connects MNT between Ethereum and Solana. Under the new Cross-Chain Token standard, Mantle gains full control over its token pools and transfer settings. Chainlink CCIP secures every transfer through 16 independent node operators, native rate limits that act as circuit breakers, and SOC 2 Type 2 compliance — meeting the institutional security standards required by major financial institutions. The migration is scheduled from July 9 to July 15, during which the Super Portal will be temporarily suspended. Existing MNT on Ethereum and Solana remains unaffected.

The move adds to a broader industry shift. More than $7.2 billion in cross-chain and wrapped assets have migrated from LayerZero to Chainlink CCIP since May, following the $292 million Kelp bridge exploit that increased scrutiny of LayerZero-powered bridge configurations. Other projects that made the switch include Kelp, Lombard, Solv Protocol, Virtuals, Re and Kraken's tokenized assets. Chainlink's infrastructure now secures approximately 70 percent of DeFi and has enabled over $32 trillion in on-chain value, according to the company.

The migration positions Mantle to expand MNT across additional blockchain networks and tokenized asset markets as demand grows for moving real-world assets on-chain. Mantle's ecosystem holds more than $2 billion in community-owned assets, anchored by MNT on Bybit and supported by projects including mETH, fBTC and MI4.
