TLDR:

• Swift completed a tokenized bond interoperability trial with BNP Paribas, Intesa Sanpaolo, and Société Générale using Chainlink.
  
• Chainlink CCIP enabled cross-chain settlement of tokenized assets across 12+ major financial institutions including Citi and BNY Mellon.
  
• AI models achieved nearly 100% data consensus on corporate actions records validated through the Chainlink Runtime Environment.
  
• GLEIF and Chainlink partnered to deliver verifiable, cross-jurisdictional identity and compliance tools for institutional blockchain transactions.

Chainlink is building the infrastructure behind the next era of capital markets through a series of landmark partnerships and technical milestones.

Working alongside Swift, DTCC, Euroclear, and dozens of major financial institutions, the platform is connecting traditional finance with blockchain networks.

From tokenized bond settlements to AI-powered corporate actions processing, the groundwork for a new financial system is taking shape across both legacy and emerging infrastructure.

Connecting Traditional Finance to Blockchain Networks

Swift, the messaging standard connecting over 11,500 financial institutions across 200+ countries, recently completed a major digital asset interoperability trial.

The initiative involved tokenized bond transactions with BNP Paribas Securities Services, Intesa Sanpaolo, and Société Générale (FORGE).

It demonstrated how Swift can orchestrate tokenized asset transactions across blockchains and existing enterprise systems.

This trial marks a turning point in how traditional banking infrastructure interacts with distributed ledger technology.

The foundation for this milestone was laid through earlier collaboration between Swift, Chainlink, and UBS Asset Management. That work demonstrated cross-chain settlement of tokenized assets using existing Swift fiat payment rails.

More than 12 world-leading financial organizations participated, including Citi, BNY Mellon, Euroclear, Clearstream, and Lloyds Banking Group. The results established a replicable framework now being extended across Swift’s global network.

Chainlink’s Cross-Chain Interoperability Protocol (CCIP) serves as the technical backbone enabling settlement across public and private blockchains. Banks can now access on-chain environments while operating within familiar Swift messaging standards.

This removes the need for institutions to rebuild existing infrastructure from the ground up. Instead, blockchain connectivity becomes an extension of systems already trusted by thousands of institutions worldwide.

At Sibos 2024, Chainlink Co-Founder Sergey Nazarov presented these capabilities to capital markets participants. The showcase demonstrated how Swift integration with blockchains works through existing standards and Chainlink infrastructure.

Institutions can streamline interoperability without sacrificing the compliance frameworks they already operate within. This approach directly addresses one of the most persistent barriers to institutional blockchain adoption.

As part of the Monetary Authority of Singapore’s Project Guardian, Swift, UBS Asset Management, and Chainlink went further. They demonstrated the issuance and settlement of tokenized funds using traditional Swift fiat payment rails.

Digital asset transactions settled through infrastructure already used by institutions across more than 200 countries. That proof of concept confirmed that tokenized finance and conventional payment systems can operate as one unified layer.

Building a Shared Data Foundation for Capital Markets

At Sibos 2025, Chainlink and 24 of the world’s largest financial institutions announced Phase 2 of their corporate actions initiative. Partners include Swift, DTCC, Euroclear, UBS, and Wellington Management.

The phase introduces a production-grade system with new data attestor and contributor roles assigned to trusted institutions. These roles allow participating organizations to validate and enrich AI-extracted corporate actions records with verifiable accuracy.

The Chainlink Runtime Environment (CRE) managed the orchestration of multiple AI model outputs throughout the testing period. Confirmed results were converted into ISO 20022-compliant messages and delivered through the Swift Network.

At the same time, Chainlink CCIP distributed identical records across DTCC’s blockchain ecosystem and additional chain environments. Post-trade systems, smart contracts, and custodians could all access the same data simultaneously.

During testing, AI models reached nearly 100% data consensus across all evaluated corporate actions records. The system processed multilingual disclosures written in Spanish and Chinese, broadening its global coverage across jurisdictions.

Cryptographic attestation by designated institutions created a verifiable chain of custody for each corporate action. Data accuracy for confirmed records reached 100%, establishing a new reliability standard for the industry.

This infrastructure produces what the initiative calls an on-chain golden record. It functions as a real-time, attested source of truth accessible by both blockchain platforms and traditional financial systems.

Tokenized equities can now reference the same confirmed data across public and private chains. That synchronization creates the conditions for greater automation across on-chain markets going forward.

The Global Legal Entity Identifier Foundation (GLEIF) extended this infrastructure further through a strategic partnership with Chainlink. Their combined solution integrates GLEIF’s verifiable Legal Identity Identifier with Chainlink’s Cross-Chain Identity and Automated Compliance Engine.

Institutions can now verify asset provenance, enforce compliance policies programmatically, and meet regulatory requirements across multiple jurisdictions. Taken together, these layers of infrastructure form the backbone of a capital markets system built for the era ahead.
