<p><a href="https://x.com/Mantle_Official" rel="noopener noreferrer nofollow">@Mantle_Official</a> has confirmed it is migrating its Super Portal from <a href="https://x.com/LayerZero_Core" rel="noopener noreferrer nofollow">@LayerZero_Core</a> to <a href="https://x.com/Chainlink" rel="noopener noreferrer nofollow">@Chainlink</a>'s Cross-Chain Interoperability Protocol (CCIP), the latest in a string of high-profile departures from LayerZero that now totals over $7.2 billion in migrated value.</p><h2 id="a-growing-exodus-from-layerzero">A Growing Exodus From LayerZero</h2><p>The backdrop to Mantle's move is a security incident that rattled the cross-chain sector. <cite>The shift accelerated after a $292 million exploit drained 116,500 rsETH from Kelp DAO's LayerZero-powered bridge in April 2026.</cite><cite>The Kelp DAO exploit was not a failure of LayerZero's core smart contracts, but of its flexible security model. LayerZero allows applications to select their own Decentralised Verifier Networks (DVNs), off-chain actors responsible for validating events on a source chain before triggering an action on a destination chain. In the Kelp DAO case, the DVN was configured as a 1-of-1 set, meaning a single compromised verifier was sufficient to authorise fraudulent transfers.</cite></p><p>That incident prompted a broad reassessment of cross-chain infrastructure across DeFi. Mantle joins Kelp DAO and Lombard Finance in the move to CCIP. <cite>Lombard migrated its over $1 billion in bitcoin-backed assets from LayerZero to Chainlink CCIP after a security review following the Kelp DAO exploit.</cite> Other protocols including Solv, Re.xyz, and Kraken have made similar moves. <cite>Johann Eid, chief business officer at Chainlink Labs, described the trend as "a continued flight to safety across the industry."</cite></p><h2 id="why-protocols-are-choosing-ccip">Why Protocols Are Choosing CCIP</h2><p><cite>Chainlink's CCIP operates on a different, less flexible model. Each cross-chain lane is secured by a set of at least 16 independent, Chainlink-operated node operators, creating a high threshold for collusion or compromise. CCIP also integrates a separate Risk Management Network that monitors for anomalous activity and enforces value-based rate limits on each lane, acting as a circuit breaker to cap potential losses.</cite><cite>Chainlink recently completed a SOC 2 Type 2 examination for CCIP, a compliance certification typically associated with enterprise cloud providers and financial infrastructure companies, making it the only major oracle and interoperability provider with that tier of certification. SOC 2 Type 2 means an independent auditor spent months verifying that Chainlink's security controls actually work as advertised over a sustained period.</cite></p><p>For Mantle, the decision aligns with a broader platform strategy. <cite>The project said it is "thrilled to adopt the Chainlink standard," with its head of BD, Mark Veer, adding that the integration "enhances Mantle's cross-chain capabilities and strengthens our alignment with Chainlink's extensive ecosystem."</cite><cite>Chainlink CCIP has supported over $28 trillion in cumulative on-chain transaction value and averages approximately $90 million in weekly token transfers.</cite></p><p>Meanwhile, <cite>LayerZero has since removed support for 1-of-1 DVN configurations and announced plans to move most routes toward stricter 5-of-5 verifier setups.</cite> The protocol maintains significant volume, but the reputational damage from the Kelp DAO incident continues to shape infrastructure decisions across the sector.</p><p><strong>Sources:</strong><br><a href="https://www.mantle.xyz/blog/announcements/mantle-adopts-the-chainlink-standard-to-unlock-a-secure-cross-chain-ecosystem" rel="noopener noreferrer nofollow">Mantle official blog: Mantle Adopts the Chainlink Standard</a><br><a href="https://www.coindesk.com/business/2026/05/15/lombard-joins-layerzero-exodus-as-usd4-billion-in-assets-switch-to-chainlink-s-bridge" rel="noopener noreferrer nofollow">CoinDesk: Crypto firms move $4 billion in assets to Chainlink</a><br><a href="https://crypto.news/chainlink-ccip-draws-4b-from-layerzero-exodus/" rel="noopener noreferrer nofollow">Crypto.news: Chainlink CCIP draws $4B from LayerZero exodus</a></p>
