Key Highlights
- Kraken has decided to transition from LayerZero to Chainlink CCIP for its kBTC wrapped Bitcoin offering
- The migration comes in response to a devastating $292 million security breach on Kelp DAO’s LayerZero bridge in April 2026
- More than $3 billion in total value locked has shifted from LayerZero to Chainlink infrastructure in recent months
- Kraken becomes the fourth major platform to abandon LayerZero post-hack, following Kelp, Solv, and Re
- Coinbase executed a comparable infrastructure transition to Chainlink CCIP in the previous year, affecting approximately $7 billion in wrapped assets
The cryptocurrency exchange Kraken has revealed plans to discontinue its use of LayerZero technology for kBTC, its wrapped Bitcoin product, opting instead for Chainlink’s Cross-Chain Interoperability Protocol (CCIP).
This strategic shift follows a catastrophic $292 million security incident that compromised Kelp DAO during April 2026. The breach, allegedly orchestrated by threat actors associated with North Korea’s notorious Lazarus Group, exploited vulnerabilities in Kelp’s LayerZero bridge infrastructure, which was operating with only a single-verifier setup.
In explaining the move, Kraken emphasized that Chainlink CCIP provides “enterprise-grade infrastructure with strict security and risk management requirements.”
Chainlink’s CCIP architecture mandates validation from 16 separate node operators for every cross-chain transaction. The protocol additionally features built-in rate limiting mechanisms and maintains both ISO 27001 and SOC 2 Type 2 security certifications.
Kraken’s kBTC represents a bitcoin-pegged token with 1:1 backing, first introduced in 2024. The asset currently maintains a market capitalization near $260 million with approximately $333 million in total value locked, based on DeFiLlama data.
The infrastructure overhaul encompasses multiple blockchain networks including Ethereum, Ink, Unichain, and Optimism, with additional chains planned. Chainlink will serve as the cross-chain provider for all upcoming Kraken wrapped asset products.
Mass Exodus From LayerZero Infrastructure
Kraken joins three other prominent projects that have abandoned LayerZero infrastructure following the Kelp security breach. Kelp DAO, Solv Protocol, and Re have all executed similar migrations. These three platforms collectively account for approximately $2.57 billion in total value locked.
A representative from Chainlink verified that more than $3 billion in TVL has transitioned to Chainlink infrastructure during recent weeks, including a migration from Tydro, the primary lending platform on Kraken’s Ink blockchain network.
LayerZero initially disputed responsibility for the Kelp incident. While the company had previously advised Kelp to implement a more secure multi-signer configuration, it eventually acknowledged inadequate communication around the issue.
Post-exploit investigation revealed that 47% of applications utilizing LayerZero were operating with single-verifier configurations, identical to the vulnerable setup exploited during the Kelp attack.
LayerZero has subsequently announced it will discontinue support for 1/1 Decentralized Verifier Network configurations and has initiated deployment of enhanced security protocols.
Sector-Wide Reaction
The decentralized finance sector mobilized over $320 million through the DeFi United initiative to restore rsETH backing and provide restitution to impacted users.
Coinbase implemented a parallel infrastructure migration during the previous year, designating Chainlink CCIP as the exclusive bridge solution for roughly $7 billion in wrapped token assets.
Payward, Kraken’s parent organization, has also submitted an application this month for federal trust charter status to operate as a federally regulated cryptocurrency banking institution.
