Mantle is migrating its $2.5 billion Super Portal from LayerZero's OFT standard to Chainlink's Cross-Chain Token (CCT) standard between July 9 and July 15, joining a wave of projects shifting high-value cross-chain assets to Chainlink CCIP. The move pushes announced migrations from LayerZero to Chainlink past $7.24 billion since May, as bridge security becomes the binding constraint for institutional tokenised assets.
Mantle said the switch gives it direct control over token pools and transfer settings under the CCT standard, with Chainlink's decentralized oracle network securing MNT transfers across Ethereum, Solana, and additional chains planned later. "As tokenized financial assets move from concept to scale, the infrastructure that carries them across chains cannot be an afterthought," Emily Bao, a key advisor at Mantle, said in a statement.
Why it matters
The exodus began after the $292 million Kelp bridge exploit earlier this year, which sharpened scrutiny of LayerZero-powered bridge configurations. Kelp subsequently committed to migrate more than $1.5 billion in assets to Chainlink CCIP, with Lombard bringing more than $1 billion across as well. Solv Protocol moved $700 million in tokenized bitcoin, Re transferred $475 million, Kraken shifted $330 million in wrapped assets, Virtuals Protocol relocated $700 million, and Yuzu Money transferred $54.5 million.
The infrastructure matters because cross-chain bridges remain one of crypto's largest security risks, with a single failure able to expose hundreds of millions of dollars in user assets. The trend points to institutional and tokenized-asset projects consolidating around CCIP's oracle-secured model for high-value flows, while LayerZero retains share in lower-stakes consumer and memecoin corridors.
Market impact
MNT, the native token of Mantle's network, carries more than $2.5 billion in value locked, and the migration temporarily suspends the Super Portal while existing MNT on Ethereum and Solana, along with activity on Byreal and Bybit, remain unaffected.

Why is Mantle moving from LayerZero to Chainlink CCIP?
Mantle said the switch to Chainlink's Cross-Chain Token standard gives it direct control over token pools and transfer settings, with Chainlink's decentralized oracle network securing MNT transfers across Ethereum and Solana.
-
How much value has migrated from LayerZero to Chainlink CCIP in total?
Announced migrations since May have pushed past $7.24 billion, led by Kelp at more than $1.5 billion and Lombard at more than $1 billion, alongside Mantle's $2.5 billion Super Portal.
-
When did the exodus from LayerZero start?
The shift accelerated after the $292 million Kelp bridge exploit earlier in the year, which heightened scrutiny of LayerZero-powered bridge configurations and prompted Kelp to migrate to Chainlink CCIP.
-
Which other projects have moved from LayerZero to Chainlink CCIP?
Kelp, Lombard, Solv Protocol, Re, Kraken's tokenized assets, Virtuals Protocol, and Yuzu Money have all announced migrations, collectively moving billions in wrapped and tokenized assets.
-
Will Mantle users be affected during the migration?
Existing MNT on Ethereum and Solana, along with MNT activity on Byreal and Bybit, remain unaffected. Only the Super Portal is suspended during the July 9 to July 15 migration window.
