Chainlink has received SOC 2 Type 2 attestation from Deloitte & Touche LLP, a primary U.S. subsidiary of Deloitte LLP, which provides audit, assurance, and risk advisory services as part of the Big Four accounting firms.
The examinations, performed in accordance with standards established by the American Institute of Certified Public Accountants (AICPA), cover Chainlink Data Feeds including Price Feeds, Proof of Reserve, and Net Asset Value (NAV), as well as Cross-Chain Interoperability Protocol (CCIP).
In 2025, Chainlink became the first oracle platform to achieve ISO 27001 certification and SOC 2 Type 1 attestation. To date, Chainlink is the only data and interoperability oracle platform meeting all three key institutional security standards: SOC 2 Type 1, SOC 2 Type 2, and ISO/IEC 27001:2022.
As the most widely used data oracle standard, Chainlink powers the vast majority of DeFi, with more than 2,000 Chainlink Price Feeds holding over 67% of the total oracle market. By allowing smart contracts to securely access offchain data and interoperability across 70+ networks, Chainlink has enabled over $29 trillion in onchain transaction value.
The Chainlink interoperability standard, powered by CCIP, is being adopted by a growing number of leading financial institutions and market infrastructure providers such as Swift, UBS, ANZ Bank, and SBI Digital Markets to support a spectrum of stablecoins and tokenized real-world assets throughout the onchain economy.
Chainlink’s data and interoperability standards are just two facets of its comprehensive web3 infrastructure which can be leveraged to satisfy all of the data, interoperability, compliance, privacy, compute, and legacy system integration requirements of advanced onchain applications through the Chainlink Runtime Environment (CRE).
Whereas SOC 2 Type 1 evaluates the design of security controls at a specific point in time, SOC 2 Type 2 provides a more rigorous and thorough evaluation of operational performance by testing security controls over a sustained period of time. With SOC 2 Type 2 attestation, Chainlink meets the high-level security standards demanded by enterprise customers.
This milestone not only accelerates Chainlink’s adoption across DeFi and traditional finance but advances a global onchain financial system in which tokenized real-world assets deliver numerous benefits to everyday consumers.
