Chainlink co-founder Sergey Nazarov said security reviews are becoming a decisive factor in cross-chain infrastructure selection, arguing that the trend is accelerating adoption of Chainlink’s Cross-Chain Interoperability Protocol, or CCIP. In a post on X, Nazarov pointed to recent comments from Kraken, Lido Finance and Lombard Finance as evidence that larger users are placing more weight on reliability, risk controls and infrastructure design when evaluating bridging providers.
Nazarov Says Security Is Driving CCIP Adoption
Nazarov framed the shift as part of a broader change in how crypto and financial institutions evaluate infrastructure. “Our industry has started caring much more about the security and reliability of the infrastructure, standards and oracles/dependencies that it is built on top of,” he wrote. “This shift in focus towards security is already massively benefiting Chainlink because it is built with security and reliability in mind from the start e.g. 16 nodes vs 1 of 1 or 2 of 2.”
The Chainlink co-founder argued that the same factors that helped Chainlink become widely used as a data oracle provider are now influencing cross-chain decisions. “The way Chainlink became the leading data oracle is through security and reliability, I think that will happen across all categories where Chainlink deploys services for the same reasons,” Nazarov wrote. He added that this focus “makes a better system for everyone in the DeFi/TradFi industry to transact with less risk” and, in his view, leads to more Chainlink adoption over time.
Nazarov specifically identified cross-chain interoperability as an area where he sees the dynamic becoming visible. “We are now clearly seeing this dynamic take place in cross-chain interoperability, with many large users migrating onto CCIP after conducting deeper security reviews of bridging providers,” he wrote. He said more of those reviews are being published, and cited public statements from Kraken, Lido Finance and Lombard Finance to support the point.
Chainlink Points to Enterprise Reviews and Migrations
Kraken said it selected Chainlink CCIP because of enterprise-grade infrastructure and risk-management requirements. The exchange highlighted “ISO 27001 and SOC 2 Type 2 certifications,” a “secure by default architecture,” “16 independent nodes” and “native rate limits” among the reasons for its choice. Those criteria align with Nazarov’s argument that cross-chain users are increasingly evaluating infrastructure not only on connectivity, but also on operational security and default safeguards.
Lido Finance also published analysis tied to its use of CCIP for cross-chain expansion. The Lido material said Chainlink CCIP provides “strong decentralization, native safeguards, and issuer control as default protocol-level guarantees,” and said those design choices help insulate wstETH from several attack vectors associated with the Kelp and LayerZero exploit. Nazarov referenced that analysis as another example of users placing security architecture at the center of provider selection.
Lombard Finance described Chainlink CCIP as an emerging standard for high-value cross-chain infrastructure. “Chainlink CCIP has emerged as the standard in cross-chain infrastructure, providing an enterprise-grade framework to secure high-value assets,” Lombard wrote. Nazarov said more than $4 billion had migrated “in just a few weeks,” adding that he sees the industry’s preference for security and reliability as a key trend behind faster CCIP adoption.
Nazarov also linked CCIP adoption to a broader Chainlink strategy spanning data, interoperability, identity and compliance, verifiable off-chain orchestration, collateral management and tokenized asset infrastructure. He said Chainlink continues to build during quieter market periods and pointed to work involving DTCC, SGX, State Street and Fidelity International as examples of adoption across capital markets infrastructure. His central argument remains that as DeFi and TradFi systems increasingly connect, shared standards and security-focused infrastructure will become more important to institutional and on-chain finance users.
