Decentralized Oracle Network Chainlink is working with 24 world’s largest financial institutions to overhaul the way corporate actions, such as dividends, stock splits and mergers, are handled across the global market.
ChainLink operated pilots in Swift, DTCC, Euroclear and six other financial institutions. Using a combination of blockchain-based and artificial intelligence (AI), we ingested and tested real corporate action events in multiple languages.
A unified data container known as Golden Records was produced in near real time, according to a press release shared with Coindesk.
These records were distributed simultaneously to blockchain networks, such as Swift, interbank messaging systems, and legacy systems, significantly reducing the risk of manual work and errors.
This process used a blend of large-scale language models such as Openai’s GPT, Google’s Gemini, and Anthropic’s Claude to extract structured data from unstructured corporate action announcements. These were published as unified gold records in chains, creating “a single source of truth that can be easily accessed, verified and constructed by all participants.”
ChainLink’s Runtime Environment (CRE) verified model output, while Interoperability Protocol (CCIP) relayed data to blockchains, including private networks of Avalanche and DTCC.
Data Attesters encrypted the output and contributed to potentially missing data fields. According to ChainLink, the system achieved almost 100% data consensus on all test events.
Current systems for handling corporate behavior are expensive. Citi’s 2025 Asset Services Report shows that the average corporate action touches on 110,000 exchanges and costs $34 million. The global financial industry currently spends an estimated $58 billion a year on handling corporate measures.
