Chainlink Leads Initiative With 24 Financial Giants to Automate Corporate Actions Onchain

Chainlink has partnered with 24 global financial institutions, including Swift, DTCC, and Euroclear, to launch an initiative that brings corporate actions processing onchain. The project uses Chainlink’s oracle network, blockchain infrastructure, and artificial intelligence (AI) to deliver faster, more accurate, and standardized corporate action data.

Corporate actions—such as dividends, mergers, or stock splits—currently cost the financial industry an estimated $58 billion annually. The new initiative seeks to reduce costs, cut settlement errors, and increase automation by standardizing how this data is validated and shared across traditional and blockchain-based systems.

Why Corporate Actions Matter

Corporate actions are any events initiated by a company that affect shareholders or bondholders. These include:

• Dividend payments
• Mergers and acquisitions
• Stock splits and reverse splits
• Rights issues
• Tender offers

Today, processing these events remains inefficient. According to Citi’s 2025 Asset Servicing report, the average corporate action event involves more than 110,000 firm interactions and costs $34 million to process. Automation rates remain under 40%, while manual data checks are still common across institutions. Costs are rising at about 10% per year, adding pressure to an already inefficient system.

The issue is obvious: without better data standards and automation, firms will continue to face high costs and settlement risks. These inefficiencies increase operational risks and delay settlement, making standardization a high-priority issue across global finance.

How Chainlink and Partners Are Tackling the Problem

The initiative is being developed in multiple phases.

Phase 1

In Phase 1, Chainlink, Swift, Euroclear, and six financial institutions tested whether large language models (LLMs)—such as OpenAI’s GPT, Google’s Gemini, and Anthropic’s Claude—could extract structured data from unstructured corporate action announcements. The results were published onchain as unified “golden records,” creating a shared and verifiable source of truth.

Phase 2

Phase 2 introduced a production-grade deployment, expanding both speed and global coverage. Key developments include:

• Chainlink Runtime Environment (CRE): Validates multiple AI model outputs, transforms the results into ISO 20022-compliant messages, and transmits them to the Swift Network.
• Chainlink Cross-Chain Interoperability Protocol (CCIP): Distributes confirmed records across DTCC’s blockchain and other public and private networks, ensuring synchronized access.
• Institutional roles: New roles for attestors and contributors cryptographically confirm data accuracy and fill missing fields, creating a verifiable chain of custody.

During testing, the system achieved nearly 100% agreement among AI models and processed data in multiple languages, including Spanish and Chinese.

Who Is Involved

The list of participants includes a wide range of financial infrastructures, banks, and asset managers:

• Financial Market Infrastructures: Swift, DTCC, Euroclear, SIX, TMX, CEVALDOM, Grupo BMV, ADDX, Orbix Technology, Marketnode, Wamid
• Banks and Asset Managers: UBS, DBS Bank, BNP Paribas Securities Services, ANZ, Wellington Management, Schroders, Zürcher Kantonalbank, Vontobel, CTBC Bank, Causeway Capital Management, Sygnum Bank, AMINA Bank, Zand Bank

The involvement of such a broad group suggests a strong industry-wide push toward standardizing corporate action processing.

The Role of Chainlink

Chainlink provides the technical backbone for this initiative. Its Decentralized Oracle Networks (DONs) connect offchain systems with smart contracts, enabling real-time data validation and automation.

The CRE validates AI outputs, while CCIP ensures that data can flow across both blockchain and traditional systems. This combination allows:

• Faster reconciliations
• Reduced settlement errors
• Lower operational risks
• Simultaneous access across infrastructures

Chainlink’s role extends beyond this initiative. As of September 2025:

• It secures over $103 billion in assets via oracle feeds.
• Supports more than 2,500 projects.
• Has grown from $23 billion in secured assets in early 2024 to $103 billion.

Tokenization and Onchain Synchronization

A major outcome of the initiative is enabling tokenized equities to reference the same standardized records across blockchains and traditional systems. Tokenization—the process of converting real-world assets into digital tokens—has surged, with tokenized assets excluding stablecoins reaching $30 billion in 2025, up 253% year-to-date.

By aligning corporate actions with tokenized markets, the initiative:

• Improves synchronization across systems.
• Provides real-time, verifiable data for both custodians and smart contracts.
• Reduces discrepancies in corporate action events tied to tokenized assets.

Industry Perspectives

Chainlink co-founder Sergey Nazarov highlighted the importance of solving corporate actions for tokenized equities:

“Being able to solve the data validation problem of corporate actions using AI Oracle Networks from Chainlink is a big leap forward in what AI Oracle Networks are capable of, showing that multiple AIs can come to consensus on critical information inside of a Decentralized Oracle Network.” 

Analysts at investment bank Jefferies also emphasized Chainlink’s growing role as a bridge between traditional finance and blockchain. With LINK used for service payments, node operations, and staking, demand for Chainlink’s infrastructure could strengthen as tokenization expands.

Future phases of the initiative are expected to address more complex corporate actions, such as stock splits and mergers. Additional work will expand support for different jurisdictions and currencies, while adding stronger privacy and governance controls to meet compliance requirements.

Conclusion

The partnership between Chainlink, Swift, DTCC, Euroclear, and 21 other financial institutions advances the standardization of corporate actions onchain. By combining AI, blockchain, and oracle technology, the initiative provides a near real-time, validated, multilingual solution that reduces costs and risks for global finance.

The system already demonstrates high accuracy, ISO 20022 compliance, and seamless integration with both blockchain and traditional infrastructure. As tokenization continues to expand, the collaboration places Chainlink at the center of efforts to synchronize corporate actions across markets.
