Chainlink has reached two significant security milestones by obtaining ISO 27001 certification and SOC 2 Type 1 attestation. These assessments cover Chainlink Data Feeds, including Price Feeds and SmartData (Proof of Reserve and Net Asset Value), all supported by the Chainlink Data standard, as well as the Cross-Chain Interoperability Protocol (CCIP), Chainlink's interoperability standard. Deloitte & Touche LLP independently conducted the evaluations following the American Institute of Certified Public Accountants (AICPA) attestation standards. Chainlink is the first in the blockchain industry to secure both certifications for data and interoperability oracle platforms.
As the dominant data oracle standard in DeFi, holding around 68% market share by total value secured (TVS), Chainlink's data standard safeguards over $90 billion in total value and has facilitated tens of trillions in onchain transaction volume. Top DeFi protocols like Aave, GMX, Ether.fi, Pendle, and Compound rely on Chainlink’s infrastructure. Furthermore, CCIP is seeing growing adoption among leading financial institutions, tokenized asset issuers, and DeFi platforms, including Swift, UBS, ANZ Bank, and SBI Digital Markets, to enable seamless cross-blockchain interaction.
Chainlink’s oracle platform extends beyond these certifications, encompassing various oracle standards and a comprehensive developer platform that supports advanced onchain applications. This platform caters to diverse needs such as data, interoperability, compliance, privacy, compute, and legacy system integration, consolidating them into a single solution. The core Chainlink technology stack comprises essential oracle standards, services, end-to-end solutions, and a decentralized computation runtime that underpins the entire ecosystem.
The ISO 27001 certification validates Chainlink’s robust Information Security Management System (ISMS) that covers infrastructure, development, operations, administration, and security for CCIP, Price Feeds, and SmartData Feeds. This certification demonstrates compliance with stringent international benchmarks for security, availability, and confidentiality across the platform. Meanwhile, the SOC 2 Type 1 attestation confirms a strong set of security and operational controls designed to ensure compliant, reliable oracle services that protect organizational interests and client security.
Achieving these certifications represents a critical validation of Chainlink’s readiness as enterprise-grade infrastructure, especially for integration by large financial institutions. SOC 2 compliance, in particular, is a key criterion for security-conscious businesses evaluating third-party vendors. With these credentials, Chainlink reinforces confidence among financial institutions to employ its standards and oracle services in secure, compliant onchain use cases such as Delivery vs. Payment (DvP) settlement, stablecoin servicing, and onchain data distribution.
The certified Chainlink services include:
- CCIP: A cross-chain oracle protocol enabling secure transfer of data and value across public and private blockchains, unifying liquidity and supporting advanced cross-chain applications.
- Chainlink Price Feeds: Providing reliable, real-time financial market data onchain for pricing assets in lending protocols, stablecoins, and other financial applications.
- Chainlink Proof of Reserve: Verifying offchain and cross-chain reserves backing wrapped and tokenized assets to prevent infinite mint attacks and assure full collateralization.
- Chainlink NAVLink: Supplying Net Asset Value (NAV) data onchain to facilitate tokenized fund issuance and automate onchain subscription and redemption via fiat or stablecoins.
Establishing secure, certified standards for data and cross-chain oracles is crucial to unlocking the future of onchain finance, where tens of trillions in real-world assets will be tokenized and transacted seamlessly by global financial leaders.
