BARD Mantle adopts Chainlink CCIP as the cross-chain standard, replacing LayerZero due to security issues.
Mantle (MNT) has officially adopted Chainlink (LINK)\'s Cross-Chain Interoperability Protocol (CCIP) as its cross-chain communication standard, replacing the previously used LayerZero (ZRO) protocol. The decision follows a broader industry trend-more than $7.24 billion in assets have been relocated from LayerZero to Chainlink CCIP since May.
Why this switch is significant
This move is not an isolated incident, but part of a major shift in the decentralized finance (DeFi) ecosystem. Several large projects have been migrated, including KelpDAO ($1.5 billion), Lombard (BARD,$1 billion), Solv Protocol (SOLV,$700 million), Virtuals Protocol (VIRTUAL,$700 million), Re (RE,$470 million), Kraken ($330 million), and Yuzu Money ($54.5 million).
The migration wave was triggered by a security incident involving LayerZero-the cross-chain bridge that was used when KelpDAO\'s rsETH was hacked. The incident exposed vulnerabilities in bridging security and prompted extensive review and replacement of cross-chain standards across the industry.
Security is a core driver
Cross-chain bridges have long been a key vulnerability point in the encryption ecosystem. Hacking attacks on these bridges have caused billions of dollars in losses over the past few years. The KelpDAO event became a catalyst for protocols to prioritize security over convenience or existing integration.
Chainlink\'s CCIP is designed to focus on security and reliability, relying on Chainlink\'s mature oracle network and multi-layer verification mechanism. This architecture is designed to reduce the risk of vulnerabilities that occur frequently in other cross-chain solutions.
Implications for broader markets
Mantle\'s decision to adopt CCIP suggests that the market is increasingly leaning towards protocols that provide strong security guarantees. For users and developers, the shift could mean safer cross-chain transactions, lower risk of financial loss, and greater confidence in the infrastructure that supports DeFi applications.
However, migration also brings a transition period. Existing applications and smart contracts built based on LayerZero need to be updated or migrated, which may cause temporary friction. But in the long run, it is expected to form a safer and more resilient cross-chain ecosystem.
Conclusion
Mantle\'s adoption of Chainlink CCIP as a cross-chain standard is an important vote of confidence in security-focused infrastructure. With more than $7.24 billion in assets migrating from LayerZero, this trend highlights the industry\'s growing focus on protecting user funds. As the DeFi ecosystem matures, such decisions may become more common and shape the future of cross-chain interoperability.
Frequently Asked Questions
Q1: Why did Mantle replace LayerZero with Chainlink CCIP?
The switch stems from security concerns-LayerZero was used as a bridging protocol in the KelpDAO rsETH incident. Mantle and other protocols prioritize security by using Chainlink CCIP.
Q2: How many assets have been migrated from LayerZero to Chainlink CCIP?
Since May, more than US$7.24 billion in assets from major projects such as KelpDAO, Lombard, and Solv Protocol have been announced to be relocated to Chainlink CCIP.
Q3: What does this mean for users of Mantle and other protocols?
Users will receive improved security for cross-chain transactions, but may experience a transition period as existing applications and smart contracts need to be updated to adapt to new standards.
