TLDR
- Kraken transitions kBTC wrapped Bitcoin infrastructure from LayerZero to Chainlink CCIP
- Move triggered by April 2026 Kelp DAO bridge exploit that resulted in $292 million losses
- Industry-wide shift sees more than $3 billion in TVL move from LayerZero to Chainlink platforms
- Kraken becomes fourth major protocol to abandon LayerZero, following Kelp, Solv, and Re
- Coinbase previously adopted Chainlink CCIP for approximately $7 billion in wrapped token assets
Cryptocurrency exchange Kraken has confirmed its decision to transition away from LayerZero as the underlying cross-chain technology for kBTC, its wrapped Bitcoin offering, opting instead for Chainlink’s Cross-Chain Interoperability Protocol (CCIP).
The strategic shift follows a devastating April 2026 security breach at Kelp DAO that resulted in $292 million in stolen funds. Security researchers believe the attack was orchestrated by North Korea’s notorious Lazarus Group, who exploited vulnerabilities in Kelp’s LayerZero-based bridge operating with a single-verifier setup.
According to Kraken’s official statement, the exchange selected Chainlink CCIP due to its “enterprise-grade infrastructure with strict security and risk management requirements.”
Chainlink’s CCIP infrastructure operates with 16 independent node operators that must validate every cross-chain transaction. The protocol features built-in rate limiting mechanisms and maintains both ISO 27001 and SOC 2 Type 2 security certifications.
Launched in 2024, Kraken’s kBTC maintains a 1:1 backing ratio with Bitcoin. Current data from DeFiLlama shows the token commands approximately $260 million in market capitalization with around $333 million in total value locked.
The infrastructure transition encompasses multiple blockchain networks including Ethereum, Ink, Unichain, and Optimism, with additional chains planned. Chainlink will provide infrastructure support for all future wrapped asset products from Kraken.
A Pattern of Departures From LayerZero
Kraken represents the fourth significant protocol to discontinue LayerZero infrastructure following the Kelp security incident. Previous departures include Kelp DAO itself, along with Solv Protocol and Re. Combined, these three protocols account for approximately $2.57 billion in total value locked.
A Chainlink representative verified that more than $3 billion in TVL has transitioned to Chainlink infrastructure in recent weeks, including assets from Tydro, the primary lending protocol operating on Kraken’s Ink blockchain network.
LayerZero initially disputed accountability for the Kelp breach. While the company had previously advised Kelp to implement a more secure multi-signer configuration, LayerZero later acknowledged inadequate communication contributed to the incident.
Post-exploit investigation revealed that 47% of applications utilizing LayerZero infrastructure operated with single-verifier configurations, identical to the 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.
Industry Response
The decentralized finance ecosystem mobilized through the DeFi United initiative, successfully raising over $320 million to restore rsETH backing and provide compensation to impacted users.
Coinbase executed a comparable infrastructure migration last year, designating Chainlink CCIP as the exclusive bridge solution for approximately $7 billion in wrapped token assets.
In related corporate developments, Kraken’s parent entity Payward filed an application this month seeking federal trust charter status to operate as a federally chartered cryptocurrency banking institution.
