Mantle is migrating its Super Portal from LayerZero's Omnichain Fungible Token standard to Chainlink's Cross-Chain Interoperability Protocol, with the portal suspended between July 9 and July 15 during the transition. The migration follows a broader trend of projects moving away from LayerZero after the $292 million Kelp bridge exploit earlier this year raised security concerns about cross-chain infrastructure. The move pushes total announced migrations from LayerZero to Chainlink CCIP above $7.24 billion since May, with Mantle's MNT token representing more than $2.5 billion in locked value across the network.
Mantle Suspends Super Portal for LayerZero to Chainlink Migration
Mantle's Super Portal, co-developed with Bybit, enables transfers of MNT between Ethereum and Solana. During the migration between July 9 and July 15, the portal will be suspended. Existing MNT on Ethereum and Solana, along with MNT activity on Byreal and Bybit, will remain unaffected. Support for additional blockchain networks is planned.
Under the new setup, Chainlink CCIP will secure MNT transfers using its decentralized oracle network. Mantle said the migration gives it direct control over token pools and transfer settings through the Cross-Chain Token standard.
"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.
Cross-Chain Migrations Exceed $7.24 Billion Following Kelp Exploit
The current wave of migrations began after the $292 million Kelp bridge exploit earlier this year. The incident increased scrutiny of LayerZero-powered bridge configurations and pushed projects managing large pools of wrapped, tokenized, or cross-chain assets to review their infrastructure.
Kelp announced it would migrate more than $1.5 billion in assets to Chainlink CCIP. Since then, other projects have followed. Solv Protocol migrated $700 million in tokenized bitcoin, Re moved $475 million, Kraken transferred $330 million in wrapped assets, Lombard migrated more than $1 billion, Virtuals Protocol moved $700 million, and Yuzu Money transferred $54.5 million.
LayerZero remains one of the most widely used cross-chain messaging protocols. The protocol faces pressure from the migration wave as multiple projects with billions of dollars in assets moved to a rival protocol in a short period.
Chainlink CCIP Provides Decentralized Oracle Network Security
Chainlink's Cross-Chain Token standard is designed to support token movement across chains while giving issuers control over how assets are minted, burned, locked, or released. The standard allows projects to manage token pools and transfer settings directly.
Bridges allow tokens and data to move between blockchains, but they concentrate risk because a single failure can expose large amounts of user assets. The migration reflects a reassessment of cross-chain infrastructure after a year in which bridge security has become one of the most important risk areas in crypto.
FAQ
What is Mantle migrating from LayerZero to Chainlink CCIP?
Mantle is migrating its Super Portal from LayerZero's Omnichain Fungible Token standard to Chainlink's Cross-Chain Interoperability Protocol. The Super Portal, co-developed with Bybit, enables transfers of MNT between Ethereum and Solana. The portal will be suspended between July 9 and July 15 during the migration.
How much value has migrated from LayerZero to Chainlink since May?
Total announced migrations from LayerZero to Chainlink CCIP exceed $7.24 billion since May. The migration wave began after the $292 million Kelp bridge exploit earlier this year. Projects that migrated include Kelp ($1.5 billion), Solv Protocol ($700 million), Lombard (more than $1 billion), Kraken ($330 million), Re ($475 million), Virtuals Protocol ($700 million), and Yuzu Money ($54.5 million).
Why did Mantle choose Chainlink CCIP for cross-chain transfers?
Mantle said the migration to Chainlink CCIP gives it direct control over token pools and transfer settings through the Cross-Chain Token standard. Chainlink CCIP secures MNT transfers using its decentralized oracle network. Emily Bao, a key advisor at Mantle, stated that "the infrastructure that carries them across chains cannot be an afterthought" as tokenized financial assets move from concept to scale.
