Day 1

Major Announcement: Chainlink and 24 Leading Financial Market Participants Advance Industry Initiative To Solve $58 Billion Corporate Actions Problem

Chainlink, together with 24 of the world’s largest financial market infrastructures and institutions, including Swift, DTCC, and Euroclear, is establishing a new, unified infrastructure for streamlining corporate actions processing. This is accomplished by leveraging the Chainlink oracle platform, blockchains, and artificial intelligence (AI) to extract, validate, and deliver corporate actions data in a standardized format across both blockchain networks and traditional financial systems. Our work represents a transformative approach to how a cross-market standard for corporate actions processing can be implemented across the global financial system.

The full list of participants in this industry initiative includes financial market infrastructures Swift, DTCC, Euroclear, SIX, TMX, CEVALDOM, Grupo BMV, ADDX, Orbix Technology, Marketnode, and Wamid, as well as leading asset managers and banks UBS, DBS Bank, BNP Paribas’ Securities Services business, ANZ, Wellington Management, Schroders, Zürcher Kantonalbank, Vontobel, CTBC Bank, Causeway Capital Management, Sygnum Bank, AMINA Bank, and Zand Bank.

This implementation builds on Phase 1 of our work, where Chainlink, Swift, Euroclear, and six financial institutions demonstrated that large language models (LLMs) could extract structured data from unstructured corporate action announcements and publish it onchain as a unified golden record—a single source of truth that all participants can easily access, verify, and build upon. While Phase 1 proved the technical viability of this approach and demonstrated that corporate actions processing could be reduced drastically, Phase 2 advances it into a production-grade solution that satisfies the requirements of today’s leading financial institutions.

Swift Announces New Blockchain-Based Ledger

As a landmark moment for the global financial system and blockchain industry alike, Swift announced at Sibos 2025 it is launching a new blockchain-based ledger.

We congratulate our partner Swift and the broader Swift community on adopting blockchains and oracle networks as a key next step, validating the clear value that blockchain technology and oracle networks bring to modernizing the financial system.

As noted by Swift, the ledger is a natural extension of Swift’s progressive ecosystem innovation and live digital asset trials over the past two years.

Over more than seven years, Chainlink and Swift have collaborated across numerous initiatives, all with a common theme of enabling financial institutions to connect to blockchain networks using their existing infrastructure and messaging standards.

For a brief history of some of the crucial work that has taken place between Swift and Chainlink over the years, read this blog:

Day 2

Major Announcement: Chainlink Advances Tokenized Fund Workflows With Swift Messaging in Collaboration With UBS

Chainlink announced a landmark technical solution enabling financial institutions worldwide to manage digital asset workflows directly from their existing systems using Swift messaging and the Chainlink Runtime Environment (CRE). With Swift messages and CRE, banks and institutions can seamlessly access blockchains through the same Swift infrastructure they have relied upon for decades. This shows how institutions can access blockchains without needing to upgrade to new infrastructure, replace their existing processes, or integrate new identity and key management solutions.

A first use case involved a technical and operational pilot with UBS Tokenize, the in-house tokenization unit of UBS. Subscriptions and redemptions for a tokenized fund smart contract from UBS were triggered using ISO 20022 messages through CRE and Swift infrastructure. CRE received the Swift messages, which then triggered subscription and redemption workflows in the Chainlink Digital Transfer Agent (DTA) technical standard. 

This new development builds on Swift, Chainlink, and UBS’ past tokenized asset use case in the Monetary Authority of Singapore’s (MAS) Project Guardian in 2024, demonstrating the technical and operational possibility for settlement of tokenized fund subscriptions and redemptions using offchain cash settlement via Swift. 

Major Announcement: Introducing the Chainlink Digital Transfer Agent (DTA) Technical Standard

We’re excited to introduce the Chainlink Digital Transfer Agent (DTA) technical standard—a comprehensive set of technical standards that define how transfer agents and fund administrators can expand their operations onchain to support tokenized assets, while remaining aligned with existing regulatory frameworks.

The Chainlink DTA technical standard leverages multiple time-tested Chainlink capabilities to provide the easiest and most reliable path for market participants to launch their own onchain transfer agency services and capture the emerging opportunity of tokenized financial markets.

Now live in production, and starting with tokenized investment funds as the initial product use case, the Chainlink DTA technical standard allows transfer agents, fund administrators, issuers, distributors, and custodians to quickly and easily offer the following services:

• Real-time subscription and redemption processing of tokenized funds across multiple blockchains.
• Seamless integration of pre-built fiat and digital asset settlement workflows, reducing the need for manual reconciliation.
• Programmable compliance enforcement directly in the transaction flow, powered by Chainlink Automated Compliance Engine (ACE), eliminating fragmented eligibility checks.
• An onchain golden record of fund lifecycle activities that is automatically synchronized with each transaction rather than via delayed reconciliation.
• Cross-chain interoperability for tokenized funds, removing the siloed nature of single-chain tokenization initiatives.
• Transparent, auditable records that build regulator and market participant confidence, with extensibility to additional products beyond investment funds such as ETFs, corporate debt, and private equity.

UBS uMINT, the token corresponding to UBS Asset Management’s tokenized money market investment fund, is the first smart contract to begin adopting the DTA technical standard.

The Chainlink DTA technical standard is being built to seamlessly run on top of the Chainlink Runtime Environment (CRE) to leverage its core capabilities, such as compatibility with legacy systems, access to fiat settlement via established payment rails, and record reconciliation with offchain systems. Furthermore, the Chainlink DTA technical standard leverages multiple standards and services within the Chainlink platform, including: 

• Cross-Chain Interoperability Protocol (CCIP) to enable multi-chain distribution of tokenized assets.
• Automated Compliance Engine (ACE) to enforce role-based controls and compliance requirements onchain.
• NAVLink Feeds to ensure accurate NAV pricing for tokenized fund subscriptions and redemptions.

If you are a financial institution and see the rising demand in tokenized assets as a large opportunity, contact Chainlink Labs to see how the Chainlink DTA technical standard can help you launch onchain transfer agency services. You can also explore the technical documentation and developer resources for a deeper look into the architecture and functionality of the Chainlink DTA technical standard.

Day 3

Major Announcement: GLEIF and Chainlink Form Strategic Partnership to Bring Institutional-Grade Identity Solution to Blockchain Industry

The Global Legal Entity Identifier Foundation (GLEIF) has entered into a strategic partnership with Chainlink to establish a new institutional-grade identity solution for the blockchain industry.

The solution combines GLEIF’s verifiable Legal Identity Identifier (vLEI) with Chainlink’s infrastructure for Cross-Chain Identity (CCID) and Automated Compliance Engine (ACE) to enable digital asset transactions that are verifiable, compliant, and trusted across jurisdictions while preserving user privacy.

While digital assets are set to transform global finance, the lack of a verifiable identity solution onchain has held back institutional adoption. By enabling verifiable identity data to be embedded directly into onchain assets and smart contracts, GLEIF and Chainlink are empowering institutions and tokenization platforms to:

• Programmatically verify asset provenance
• Automatically enforce compliance policies
• Reliably recover control over assets if private cryptography keys are compromised
• Seamlessly meet compliance requirements for regulatory frameworks across the globe

This removes the final hurdles for banks, asset managers, and institutional investors ready to implement digital asset solutions at scale and opens up hundreds of trillions in institutional capital to flow onchain.

This new solution unlocks a number of new capabilities for asset issuers and smart contract applications in order to realize the full potential of tokenized finance, including:

• Stablecoin issuers can prove their legal identity at the contract level, ensuring regulators, markets, and users can distinguish between genuine, reserve-backed stablecoins and fraudulent imitations.
• Asset issuers and smart contract applications can unlock seamless compliance with regulations across different jurisdictions, such as Europe’s Markets in Crypto-Assets Regulation (MiCA), the U.S. Financial Data Transparency Act (FDTA), and the Financial Action Task Force (FATF) requirements.
• Custodians and Virtual Asset Service Providers (VASPs) can verify that receiving addresses meet FATF Travel Rule requirements without exposing customer data.
• Banks and asset managers can issue tokenized assets with verifiable provenance throughout the asset’s lifecycle.
• Enterprises can restore control of compromised contracts using role-based recovery mechanisms.
