Overview
- Mantle announced it is migrating its Super Portal, which moves MNT between Ethereum and Solana, from LayerZero’s Omnichain Fungible Token standard to Chainlink’s Cross-Chain Token standard and will suspend portal transfers for a planned multi-day migration.
- Projects have moved more than $7.2 billion in cross-chain and wrapped assets onto Chainlink’s Cross-Chain Interoperability Protocol since May, a total compiled from public migration announcements.
- The exodus picked up speed after a major bridge exploit earlier this year exposed flaws in some LayerZero configurations, prompting teams to seek oracle-based message verification and tighter operational controls.
- Mantle and other migrating projects say Chainlink’s CCIP secures cross-chain messages using its decentralized oracle network and that the CCT standard lets them set transfer policies and manage token pools directly.
- The wave of migrations underscores that bridges remain a high-risk part of crypto infrastructure and could lead to more planned suspensions, technical audits, and changes in custody and governance for tokenized assets.
