Swift Achieves Blockchain Interoperability Milestone With Chainlink and Major Banks

• Swift completed cross-chain tokenized bond trials with BNP Paribas, Intesa Sanpaolo, and Société Générale.
• Chainlink CCIP enabled secure distribution of AI-validated corporate action records across blockchains.
• GLEIF and Chainlink provide verifiable institutional identity for compliant blockchain transactions globally.

Swift has completed a key milestone in digital asset interoperability, working with major European banks on tokenized bond trials. BNP Paribas Securities Services, Intesa Sanpaolo, and Société Générale participated in the initiative.

The tests showed how Swift can manage tokenized asset transactions across blockchains while maintaining existing enterprise systems. This builds on prior work with Chainlink and UBS Asset Management, which integrated traditional payment rails with blockchain settlements.

Expanding Cross-Chain Tokenized Asset Capabilities

The trials demonstrated how tokenized bonds can settle across multiple blockchain networks. Swift coordinated these transactions while keeping compatibility with existing financial systems.

Banks were able to move assets without changing current operational standards. Michael McDonough from Swift said, “Our work shows tokenized assets can be transferred across blockchains and traditional systems securely.” 

Participating banks verified transactions using Swift messaging standards, enabling seamless integration. The trial confirmed that multiple institutions can interact on-chain simultaneously.

This achievement also expands Swift’s cross-chain network. Earlier tests involved 12 major banks, including Citi, BNY Mellon, and BNP Paribas. The framework now supports tokenized bonds, funds, and other assets across public and private blockchains.

The milestone offers scalable infrastructure for global financial institutions. It reduces friction between traditional and blockchain-based systems. Swift now provides a platform to accelerate institutional adoption of tokenized assets.

Standardizing Corporate Actions Using AI and Chainlink

Swift and Chainlink are working to standardize corporate actions data across blockchains and traditional systems. Phase two introduced data attestor and contributor roles to confirm AI-extracted records. Verified institutions enrich these records, achieving nearly 100% accuracy in corporate actions processing.

The Chainlink Runtime Environment transforms validated data into ISO 20022-compliant messages for Swift. Chainlink CCIP then distributes the records across blockchain networks. This creates a real-time on-chain golden record accessible to smart contracts, custodians, and post-trade systems simultaneously.

AI processing also supports multilingual corporate disclosures, including Spanish and Chinese. This allows global institutions to access accurate and verified information. Tokenized equities can now reference these confirmed records on multiple blockchains.

The system improves synchronization and automation across asset servicing. Institutions can track corporate actions consistently across traditional and blockchain platforms. This lays the foundation for a more efficient financial ecosystem.

Connecting Banks to Blockchain Using Existing Standards

Chainlink and Swift have enabled banks to connect to blockchains without changing existing infrastructure. Institutions can adopt blockchain efficiently while continuing to use Swift messaging standards. Sergey Nazarov, Chainlink co-founder, stated, “This framework allows financial institutions to adopt blockchain seamlessly.”

The cross-chain solution has been tested with over 12 banks, including Euroclear, Clearstream, ANZ, Citi, and Lloyds Banking Group. The tests confirmed tokenized assets can move securely across public and private blockchains. The system also supports real-time settlement for tokenized bonds and funds.

Banks can now use blockchain to improve operational efficiency. Automated processes reduce manual reconciliation work. Swift and Chainlink help institutions bridge traditional finance with blockchain technology effectively.

This integration enhances transparency while maintaining compliance standards. Institutions can safely scale digital asset operations across multiple markets. The system strengthens connectivity between conventional and decentralized financial networks.

Institutional Identity Verification for Blockchain Transactions

GLEIF partnered with Chainlink to provide institutional-grade identity verification for blockchain transactions. Using verifiable Legal Entity Identifiers (vLEIs) and Chainlink’s CCID, identity data is embedded directly into blockchain assets.

This solution enables automated compliance and verifies asset provenance across jurisdictions. It also allows recovery of assets if private keys are compromised. Institutions can now meet regulatory requirements while maintaining data privacy.

The partnership supports scalable digital asset operations globally. Tokenization platforms can programmatically verify asset ownership and enforce compliance policies. It adds trust and security to blockchain-based transactions.

Swift, Chainlink, and major banks have created a framework connecting traditional finance with blockchain. This system enables secure, real-time tokenized asset transactions and standardized corporate actions. It also allows institutions to adopt blockchain efficiently without disrupting existing processes.
