Blockchain oracle network Chainlink and 24 major financial services institutions have completed the second phase of an industry initiative to standardise and streamline corporate actions processing. Using Chainlink’s platform, blockchain, and artificial intelligence (AI), the solution has unlocked a unified golden record for corporate actions.
According to numbers published by the Depository Trust and Clearing Corporation (DTCC), corporate actions processing costs the industry US$58 billion annually. Citi’s 2025 asset servicing report revealed that the average corporate action event involves more than 110,000 firm interactions and costs US$34 million to process, but 75 per cent of market participants are still relying on manual data revalidation.
Quick actions
Phase 2 of the initiative made “substantial improvements to the speed, reach, and accessibility of corporate actions data” in order to achieve production-grade deployment.
The phase saw the Chainlink Runtime Environment (CRE) validate multiple AI model outputs and transform confirmed results into messages that were ISO 20022-compliant. These were then transmitted to the Swift network. Simultaneously, Chainlink’s Cross-Chain Interoperability Protocol (CCIP) distributed the same confirmed results across DTCC’s blockchain ecosystem as well as other public and private blockchain environments, enabling access across traditional infrastructure and blockchain-based platforms.
Data attestors and contributors were brought on board to check on data accuracy and contribute to any missing data fields. This created a verifiable chain of custody across the lifecycle of each corporate action.
Throughout the test, the system was able to achieve nearly 100 per cent data consensus agreement among AI models across all evaluated corporate actions. The architecture was also able to support multilingual processing for disclosures written in non-English languages including Spanish and Mandarin.
All golden
The solution makes possible the building of a unified golden record – described in the press release as “an attested, real-time source of truth that can be accessed simultaneously by smart contracts, custodians, and post-trade systems”. Organisations can now receive structured and validated corporate actions data in multiple languages in their existing systems in minutes, not days.
The solution also allows tokenised equities to reference the same confirmed records across public and private blockchains, thus laying the groundwork for better synchronisation and increased automation across on-chain markets.
The goal is to create a shared foundation for asset servicing across both blockchain networks and traditional financial infrastructure by standardising how corporate actions data is extracted, validated, and delivered. With the reduction of settlement errors, faster reconciliations, and lower operational risks, there is potential to save the indsutry “tens of billions of dollars” in processing costs annually, all without distrupting existing processes.
More to come
The second phase of the initiative was built on the first phase, which proved that large language models (LLMs) are capable of extracting structured data from unstructured corporate action announcements and publish it as unified golden records on chain.
The 24 institutions inolved in the second phase include Swift, DTCC, Euroclear, SIX, and BNP Paribas’ Securities Services. Findings from this phase of the initiative have been published in a report titled “Establishing a unified standard for asset servicing with the Chainlink platform, blockchains, and AI”.
Future plans for the initiative involve three main areas: building support for more complex corporate actions such as stock splits, expanding global coverage for additional jurisdictions and currencies, and introducing stronger privacy and governance controls to meet the operational and compliance needs of global financial institutions.
