Global finance is undergoing a profound and irreversible transformation, with assets, payments, and market infrastructure increasingly migrating onto blockchain networks, a paradigm shift poised to unlock unprecedented efficiencies and create entirely new financial products. This movement, known as onchain finance, is not merely an incremental technological upgrade but a fundamental re-architecture of how value is created, exchanged, and managed worldwide. Projections indicate a colossal expansion, with tokenized real-world assets (RWAs) expected to surge to an astounding $30 trillion within the next decade. Major financial institutions and market infrastructures, including interbank messaging giant Swift, are actively embracing this technological frontier, with Swift announcing the development of its own blockchain-based ledger to explore its potential.
The Dawn of Onchain Finance: A Trillion-Dollar Shift
The concept of tokenization — representing real-world assets or financial instruments as digital tokens on a blockchain — promises a revolution in market operations. It offers the potential for faster settlement times, programmability that embeds complex rules directly into assets, and the creation of novel financial instruments previously impossible within traditional frameworks. However, the path to realizing this immense potential is fraught with significant challenges, primarily centered around interoperability. The emerging landscape of hundreds of disconnected public and private blockchains, coupled with the necessity of integrating with existing, deeply entrenched financial systems, presents a complex web of technical and operational hurdles. For tokenized finance to scale globally, institutions cannot rely on fragmented "point solutions" or isolated blockchain environments. They require an end-to-end interoperability standard that seamlessly unifies cross-chain connectivity, integrates with legacy systems, ensures trusted data feeds, embeds compliance and privacy protocols, and orchestrates complex financial workflows. Chainlink, a decentralized oracle network, has positioned itself as the leading platform addressing this full spectrum of interoperability challenges, aiming to be the foundational standard for institutional tokenization on a global scale.
The journey towards onchain finance has been evolving for years, moving from nascent experiments in distributed ledger technology (DLT) to mainstream adoption discussions. Initially viewed with skepticism, blockchain has gradually proven its robustness and potential beyond cryptocurrencies, drawing the attention of central banks, commercial banks, and asset managers. The drivers for this shift are compelling: reducing operational costs, enhancing transparency, improving liquidity by fractionalizing assets, and accelerating settlement cycles from days to minutes or even seconds. However, these benefits remain largely theoretical without a robust framework to connect disparate blockchain ecosystems with each other and with the existing financial world. This is precisely where the demand for a universal interoperability standard becomes critical.
The Interoperability Imperative: Bridging Disconnected Ecosystems
The current multi-chain environment mirrors the early days of the internet before the adoption of TCP/IP. Back then, isolated networks communicated through customized, one-off connections, hindering widespread adoption and creating immense friction. Similarly, today’s blockchain landscape features diverse protocols, consensus mechanisms, governance models, and compliance rules, leading to fragmented liquidity, disconnected applications, and redundant asset versions. This complexity makes secure and efficient operations at scale exceedingly difficult for institutions. Without a shared, open interoperability standard, the industry faces a proliferation of bespoke bridging solutions, each introducing unique trust assumptions and security vulnerabilities that institutions must painstakingly assess and integrate.
To facilitate the seamless movement of data and value across the burgeoning onchain economy, an interoperability solution must enable secure cross-chain token transfers and message passing. This capability is vital not only for liquidity to flow where demand exists but also for assets and applications to be managed and synchronized across networks securely, efficiently, and in real-time.
Addressing Core Challenges: Chainlink’s Multi-Faceted Approach
Chainlink’s approach tackles four fundamental interoperability challenges that are paramount for institutional tokenization to achieve global scale:
I. Navigating the Multi-Chain Landscape
The existence of numerous public and private blockchains, each with distinct characteristics, necessitates a robust solution for cross-chain communication. Institutions require the ability to interact with assets and applications across these varied environments without being confined to a single chain or resorting to risky, custom bridges.
A significant stride in this area was demonstrated through a collaboration between SBI Digital Markets, UBS Asset Management, and Chainlink under the Monetary Authority of Singapore (MAS) Project Guardian. This pilot successfully showcased how Chainlink’s infrastructure, combined with the Digital Transfer Agent (DTA) technical standard, enables the creation of tokenized funds with automated fund management operations and transfer agency processes. Specifically, the solution allows tokenized funds to maintain their share register on one blockchain while leveraging Chainlink’s Cross-Chain Interoperability Protocol (CCIP) to process fund lifecycle activities, such as subscriptions and redemptions, on an entirely different blockchain. This innovative architecture lays the groundwork for institutional-grade onchain financial products. Winston Quek, CEO at SBI Digital Markets, underscored the significance, stating, "This architecture creates a foundation for our own onchain financial products and services to meet immediate user demand for tokenization and tokenized funds in particular. This new way of launching fund structures and administering them via smart contracts empowers both fund managers and their service providers to deliver new onchain financial products and lower operational costs to investors, both things they are actively looking for."
II. Integrating Legacy Financial Systems
The global financial system is built upon decades of robust, battle-tested infrastructure that secures trillions in value daily. This existing infrastructure, encompassing custodians, transfer agents, fund administrators, payment systems, and Central Securities Depositories (CSDs), is not obsolete but indispensable. The goal of onchain finance is not to dismantle and replace these trusted systems but to securely and standardly integrate them with blockchain technology. The primary challenge lies in the fact that these legacy systems were not designed for native blockchain connectivity, forcing institutions to rely on resource-intensive, bespoke integrations prone to delays and errors.
A universal interoperability standard must extend beyond merely connecting blockchains to define how offchain systems – including banking infrastructure, data providers, enterprise platforms, and web APIs – can directly and securely integrate with onchain environments. Such a standard would create a unified framework for operations across global finance, accelerating tokenization within existing capital markets and establishing a common model for hybrid onchain/offchain tokenized asset transactions.
This vision was further advanced through an initiative announced at Sibos 2025, involving Chainlink and 24 of the world’s largest financial institutions and market infrastructures, including Swift, DTCC, Euroclear, SIX, UBS, and Wellington Management. This collaboration focused on developing a unified infrastructure for streamlined corporate actions processing. The Chainlink Runtime Environment (CRE) orchestrates and validates outputs from multiple AI models concerning new corporate actions events, transforms these confirmed outputs into industry-standard ISO 20022 messages, and delivers them to financial institutions via the Swift network. Simultaneously, Chainlink’s CCIP distributes these confirmed records in real-time to DTCC’s blockchain ecosystem and other public and private blockchains. In this solution, Chainlink CRE and CCIP serve as critical orchestration and interoperability layers, powering the processing, validation, and cross-system distribution of corporate actions data. Sté phanie Lheureux, Director, Digital Assets Competence Center at Euroclear, highlighted the importance of this work: "Delivering scalable digital market infrastructure means aligning new solutions with the systems institutions already trust, and the Chainlink Runtime Environment makes this alignment seamless by enabling new technologies to integrate within existing workflows. Our corporate actions industry initiative with Chainlink and major financial institutions shows that industry-wide coordination around standards and interoperability are key to reaching global scale."
III. Ensuring Data Integrity, Compliance, and Privacy
Beyond mere connectivity, a universal interoperability standard must embed the essential building blocks required for sophisticated tokenized asset transactions: trusted data, automated compliance, and privacy preservation. Just as in traditional finance, nearly all onchain transactions require various data inputs, such as Net Asset Value (NAV), Assets Under Management (AUM), and Know Your Customer (KYC)/Anti-Money Laundering (AML) checks. Furthermore, transactions must adhere to embedded compliance policies and conditions, ranging from identity and investor accreditation requirements to internal business rules regarding transaction limits and operating hours. The imperative for privacy, to meet consumer and regulatory demands, adds another layer of complexity. Therefore, an interoperability standard can only achieve widespread adoption if it comprehensively supports these critical components for advanced transactions.
The Hong Kong Monetary Authority (HKMA) underscored this necessity in its report on Phase 2 of its e-HKD program. The report highlighted the results of multiple industry initiatives, including a crucial cross-chain settlement solution powered by Chainlink in collaboration with ANZ, China AMC, and Fidelity International. In this solution, these institutions leveraged Chainlink CCIP and ACE (Attestation and Computation Engine) to satisfy both institutional cross-chain interoperability and compliance requirements for the secure cross-chain settlement of tokenized assets. The solution adeptly addresses the three biggest challenges of institutional tokenized asset transactions by unifying trusted data, cross-chain connectivity, and automated compliance into a single workflow. It provides secure, high-quality data for accurate asset pricing and transfer agent operations, enables seamless value and data movement across blockchains using Chainlink CCIP, and enforces compliance by verifying onchain identity proofs against jurisdiction-specific regulatory policies through Chainlink’s ACE.
Further demonstrating Chainlink’s capabilities in this domain, phase two of the Central Bank of Brazil’s (BCB) Drex project focused on cross-border trade. Chainlink connected the BCB with the HKMA to orchestrate seamless and secure trade settlement across jurisdictions in a compliant manner. Additional participants included Banco Inter, Standard Chartered, the Global Shipping Business Network (GSBN), and 7COMm. The Chainlink platform facilitated seamless communication across the Drex platform, the Hong Kong Ensemble Network, and GSBN’s trade finance system. The Chainlink Runtime Environment (CRE) translated messages between networks, triggered electronic Bill of Lading transfers, and connected offchain systems like GSBN’s API. Chainlink CCIP provided secure cross-chain messaging, ensuring that key events like contract execution and credit release remained synchronized across all platforms. These examples, alongside Chainlink’s work with Apex Group and the Bermuda Monetary Authority (BMA) on institutional-grade stablecoin infrastructure for embedded supervision, and with the Global Legal Entity Identifier Foundation (GLEIF) for an institutional identity solution, illustrate a comprehensive approach to data, compliance, and privacy.
IV. Orchestrating Complex Financial Workflows
The final piece of the interoperability puzzle is orchestration — the ability to securely coordinate complex financial processes that span multiple blockchains, external systems, regulatory logic, and institutional workflows through a single, unified framework. Traditional smart contracts typically execute isolated functions on a single chain. However, institutional asset lifecycles are far more intricate, demanding data from pricing and compliance systems, multi-chain execution, identity verification and compliance functions, existing system integration, and conditional business logic that must run securely and reliably in parallel. Without a dedicated orchestration layer that unifies these diverse components and processes, institutions are forced to construct and maintain a complex web of bespoke integrations and custom logic. This fragmented approach invariably slows adoption, heightens operational risk, and fragments liquidity across disparate systems.
A universal interoperability standard must therefore encompass not just connectivity across chains, systems, and data sources, but also robust orchestration capabilities that weave these elements into composite workflows capable of powering real-world financial operations at scale.
UBS successfully completed the world’s first in-production, end-to-end tokenized fund workflow leveraging the Chainlink Digital Transfer Agent (DTA) technical standard as a solution to this challenge. This innovative solution harnesses key Chainlink platform capabilities, including the Chainlink Runtime Environment (CRE) for offchain computation and workflow automation, Chainlink CCIP for secure cross-chain messaging and token transfers, and Chainlink Data Feeds for reliable pricing data. This comprehensive workflow can cover every stage of the fund lifecycle, from order taking and execution to settlement and data synchronization across all onchain and offchain systems, showcasing the power of integrated orchestration.

At the core of Chainlink’s offering is the Chainlink Runtime Environment (CRE), an advanced orchestration layer designed to enable institutional-grade smart contracts. These are complex financial workflows that operate seamlessly across blockchains and offchain systems, directly addressing the critical pain point of integrating existing legacy systems with blockchain environments. Built upon CRE are open standards, each tackling a key dimension of end-to-end interoperability:
- Chainlink Cross-Chain Interoperability Protocol (CCIP): This protocol provides a highly secure and reliable standard for transferring tokens and arbitrary data messages across disparate blockchain networks.
- Chainlink Attestation and Computation Engine (ACE): ACE enables verifiable offchain computation and data attestation, crucial for embedding complex business logic, regulatory compliance, and privacy-preserving computations into onchain transactions.
- Chainlink Digital Transfer Agent (DTA) Technical Standard: This standard defines how tokenized funds and other financial instruments can be administered onchain, automating fund management operations and transfer agency processes across blockchains and existing systems.
- Chainlink Data Feeds: Providing access to tamper-proof, high-quality, and real-time data from various offchain sources, essential for accurate asset pricing, risk management, and smart contract execution.
The CRE unifies these standards on a single platform, making them composable into sophisticated workflows that interact across both onchain and offchain systems. This results in a cohesive interoperability standard that can power the entire lifecycle of tokenized asset transactions while rigorously meeting institutional-grade requirements for security, compliance, and reliability.
