This years SIBOS is the biggest one yet for Chainlink. Moving our work forward with Swift on interoperability, as well as announcing our work with the DTCC, Euroclear, UBS, DBS, BNP and many others on solving key problems like corporate actions for successful institutional tokenization by the TradFi industry. Digital Transfer Agency launching with UBS and DataLink launching with Deutsche Borse are also very big because Chainlink clearly solves two of institutional tokenization's largest challenges; on-chain transfer agency and institutional grade data for digital assets. At this SIBOS I think it has become clear to everyone in the TradFi and DeFi community that the Chainlink Stack is the only system where you can get all of your digital asset challenges solved using a single standard. It is important to remember that solving just one of these problems is not enough to make institutional transactions happen on-chain at scale. Institutional tokenization and institutional capital flows in the trillions require multiple conditions to be met; on-chain data, cross-chain connectivity, on-chain compliance, on-chain asset servicing e.g. corporate actions, legally binding transfers e.g. transfer agency and many others depending on the use case. If we want institutional tokenization to happen at scale and for that scale to turn into trillions of dollars in capital flowing on-chain, there needs to be a single global standard that solves these problems on-chain, in a way that works for both the institution and the regulators they are overseen by. More to come and very excited about the Chainlink Stacks ability to solve these problems in one standard.
At Sibos 2025, @SergeyNazarov presented how onchain standards can combine with existing systems and standards to create next-gen digital assets, including: • Introducing a major industry milestone in a global corporate actions initiative led by Chainlink in collaboration with 24 of the world’s largest financial organizations (Swift, DTCC, Euroclear, and more). • A live discussion with the DTCC’s Global Head of Digital Assets Nadine Chakar on how combining blockchains, oracles, and AI provide a real solution to the long-standing corporate actions problem. • A focus on Swift’s new blockchain-based ledger announcement that builds on existing work between Swift and Chainlink to facilitate interoperability across existing and emerging systems for various use cases. • Establishing compliance across blockchains and token standards through the Chainlink compliance standard and Cross-Chain Identity (CCID). And multiple other key developments accelerating the adoption of institutional tokenization. 🔗 Presentation slides: blog.chain.link/wp-content/u… Watch the full video now ⬇️

The great work done by the SEC’s Project Crypto has helped define how tokenized infrastructure can align with existing U.S. regulatory frameworks, an area long overdue for clarity. That groundwork is now advancing into joint roundtable discussions between the SEC and CFTC around regulatory harmonization, an increasingly strong signal that the United States is positioning itself to lead in the next phase of global finance, underpinned by decentralized infrastructure. I’m also excited to see @MikeSeligEsq being considered for the CFTC Chair. His experience as Chief Counsel of the SEC’s Crypto Task Force and as Senior Advisor to the Chairman gives him a rare combination of legal and technical expertise to navigate the U.S. through this turning point in financial innovation.

THE CHAINLINK ENDGAME The updated Chainlink vision is here. What started as a data solution is now an extensive platform of essential services for integrating the world into the onchain economy ⬇️ blog.chain.link/chainlink-or… What TCP/IP did for the Internet and the Java Runtime Environment (JRE) did for online development, Chainlink is doing for blockchains and onchain apps. In the early days of the Internet, scaling required more than innovation—it required unification and seamless orchestration. TCP/IP and the JRE emerged, bringing coherence to a fragmented digital world and abstracting away complexity so developers could focus on building. Blockchains are at the same turning point. With more chains and even more financial institutions and real-world assets moving onchain, the main challenge now is building apps that efficiently orchestrate across blockchains and existing systems. Advanced blockchain apps now involve multiple types of data, cross-chain interoperability, compliance policies, integration with legacy systems, and much more. Building these next-gen apps is nearly impossible to do in-house and overly complex if you have to rely on a growing list of vendors, who each only solve a small portion of the application’s overall requirements. Chainlink changes that. Chainlink is not just a price feed. It’s a unified oracle platform that underpins critical standards, services, and end-to-end solutions needed to unlock advanced blockchain applications: • Data oracles for publishing mission-critical data onchain • Interoperability oracles for moving data and value cross-chain • Compliance and privacy oracles for meeting regulatory and internal business requirements • Legacy system integration for seamless connecting between onchain and offchain systems • Verifiable orchestration and compute to power entire applications in a decentralized manner Like Java and TCP/IP before it, Chainlink unifies blockchains and abstracts away complexity, empowering developers and institutions to build and power the entire lifecycle of onchain use cases via a single, secure platform. Now, enterprises can efficiently build onchain apps that mirror the sophistication of traditional finance yet benefit from the transparency, security, and composability of blockchains and Chainlink technology. Chainlink is how the world integrates into the onchain economy.
Great meeting today with @SenatorTimScott, Chairman of the Senate Banking Committee, the group working on the critical new market structure bill going to the senate. This new version of the market structure bill has many advantages over past versions, enabling our industry to rapidly grow in the US with fewer limitations. I am excited by the urgency with which Senator Scott is moving this critical piece of legislation forward and how he is focused on solidifying a long-term approach by the US government towards our industry's future growth. I think our entire industry should be grateful to Senator Scott for his great work on the recently passed Genius Act and his continued efforts to create clear legislation for our industry's bright future. Thank you Senator Scott.

We're excited to announce the launch of the Chainlink Reserve, a new upgrade centered on the creation of a strategic onchain reserve of LINK tokens. blog.chain.link/chainlink-re… The Chainlink Reserve is designed to support the long-term growth and sustainability of the Chainlink Network by accumulating LINK tokens using offchain revenue from large enterprises that are adopting the Chainlink standard and from onchain service usage. The Chainlink Reserve is being built up by using Payment Abstraction to convert offchain and onchain revenue into LINK, using a combination of Chainlink services and decentralized exchange infrastructure. Demand for Chainlink has already created hundreds of millions of dollars in revenue, substantially from large enterprises that have paid offchain for access to the Chainlink Platform. With increasing demand from a number of the world’s largest banking and capital markets institutions, this form of paying for the Chainlink standard is expected to grow into the future as the industry grows. The Reserve has already accumulated over $1M worth of LINK from this early stage launch phase, which is expected to gradually grow in the coming months as more revenue is converted into LINK and placed into the Reserve. We do not expect any withdrawals from the Reserve for multiple years and thus it is expected to grow over time. We believe that as the industry demand for Chainlink’s unique capabilities increases, that adoption of Chainlink services will enable the Reserve to grow further. 🧵👇
I am truly impressed by the @realDonaldTrump administration's thoughtful approach to helping the blockchain industry achieve its full potential in the united states and beyond. I think the president's clear placing of our industry as a national priority will be seen as a critical and historic moment for our industry and for the united states financial system's role globally. This recent report highlights some of the key points that the white house has been considering. It is telling that the first few pages of the report are about oracles and clearly highlights some of the great work that the Chainlink community has been doing to bring smart contracts to the next stage of their evolution, clearly mentioning the Cross Chain Interoperability Protocol (CCIP).
TODAY: The White House has featured oracles as a key technology in its new Digital Asset Report, highlighting how Chainlink is critical infrastructure for powering stablecoins, tokenized funds, & the onchain economy. whitehouse.gov/wp-content/up… We and our entire industry are immensely grateful to President Trump (@realDonaldTrump), @SecScottBessent, @DavidSacks, @BoHines, and the President‘s Working Group on Digital Asset Markets for their leadership in advancing bipartisan digital asset innovation in the United States. The Trump Administration's thoughtful approach to our industry’s adoption and growth has created a new era for both our industry and the United States financial future. The @WhiteHouse report outlines the U.S. government’s approach to digital assets, proposing a clear regulatory framework for their issuance by addressing market structure, oversight, and consumer protection. This landmark policy initiative underscores a growing global consensus that oracle infrastructure is critical for secure, interoperable, and compliance-ready digital assets, which are key for the blockchain industry to reach its full potential. In addition to the Chainlink team’s many ongoing meetings in D.C., this report clearly affirms the significant policy momentum Chainlink has strategically worked to support for years, both in D.C. and globally. In a single platform, Chainlink enables governments, financial institutions, and Web3 developers to overcome the three most critical challenges in deploying institutional-grade blockchain applications in a regulated environment: 1. Delivering verifiable data onchain enables the creation of hyper-reliable government and institutional-grade blockchain applications by ensuring the accuracy, integrity, and transparency of critical data. 2. Connecting public chains, private chains, and legacy systems into a unified network unlocks next-generation financial markets and streamlines digital asset operations. 3. Enabling regulatory requirements and policy controls to be embedded directly into smart contracts allows for programmatic compliance with regulations, such as KYC/AML, jurisdictional restrictions, and transaction limits, all while preserving user privacy. By establishing the foundational standards needed for secure and compliant digital asset infrastructure, Chainlink is accelerating digital asset adoption in America and powering the future of U.S. financial leadership.

🧵We're proud to welcome six renowned leaders to The Digital Chamber's Advisory Board, with the addition of four existing leaders to help continue and expand The Digital Chamber’s leadership in digital asset and blockchain policy.
Excited to see our industry reaching new heights and getting global adoption from governments because of the fundamental value that our technology provides. The GENIUS Act is a huge step forward for stablecoins, forming the basis of on-chain payments for retail users in both highly developed and emerging markets. With even more fiat value now going on-chain, we are now off to the next stage of our industry's development, a Real World Asset (RWA) Tokenization boom phase. I'm excited and grateful to be at the white house today to witness the historic signing of the GENIUS Act into law by the president. This administration is doing amazing things for our industry and we should all be very grateful for how supportive they are being. Thank you @realDonaldTrump, the U.S. Congress and the U.S. Senate for supporting our industry at this critical time.
JUST IN: The U.S. House has officially passed the GENIUS Act. This is a historic moment for the crypto industry as GENIUS establishes the first clear regulatory framework for fiat-backed stablecoins in the world’s largest economy 🧵↓

Excited to see the Chainlink Standard getting adopted across multiple financial ecosystems, various chains, many high value use cases and the top institutions. The future of the global financial system is on-chain and the on-chain world has to have a globally adopted set of standards for how on-chain transactions reliably work, both inside a country's financial ecosystem and across countries, to create the new global financial system.
We are excited to announce that Westpac Institutional Bank (@Westpac) and Imperium Markets are implementing Chainlink in Project Acacia, a new joint initiative between the Reserve Bank of Australia and Digital Finance CRC (DFCRC). westpaciq.com.au/thought-lea… The Chainlink Runtime Environment (CRE) is orchestrating secure, seamless, and compliant Delivery vs. Payment (DvP) settlement of tokenized assets across blockchain markets and the existing PayTo Australia domestic payments system. This capability is key to accelerating the adoption of digital assets and bringing institutional capital onchain. The Australian central bank has estimated that tokenization can save asset issuers in Australian markets up to AUD $12+ billion annually, while Westpac highlighted that the project is a key step to understanding how digital money can support “innovations in wholesale markets by providing risk-free settlement assets, backed by a resilient architecture and an appropriate regulatory environment.” By connecting offchain payment capabilities and tokenized assets for secure DvP settlement, Westpac, Chainlink, and Imperium Markets are unlocking innovative use cases and scaling the institutional adoption of tokenized assets.

Mastercard, live for real value. Access tokens for your on-chain wallet, directly with a mastercard purchase. Liquidity to buy a tokenized asset from a stablecoin or liquidity to buy a tokenized asset from an existing payments system, is still just liquidity/purchasing power and demand for that tokenized asset. The RWA/Web3 community and digital asset/banking community all want that liquidity to easily access their tokenized assets. The challenge is getting all the liquidity of both on-chain and off-chain purchasers into one globally unified liquidity layer that can allow all of that purchasing power to access smart contracts easily. Chainlink is on track to get all the world's stablecoin liquidity and all the world's TradFi liquidity connected into smart contracts through a highly reliable, provably secure and easy to integrate ,on-chain global standard.
We’re excited to announce that Chainlink and @Mastercard have partnered to enable billions of cardholders to purchase crypto directly onchain. prnewswire.com/news-releases… Chainlink verifies and synchronizes key transaction details to enable Mastercard holders to access crypto directly onchain. This marks a major step forward in the mainstream adoption of Web3. Chainlink and Mastercard power the new @swapperfinance platform, with @ZeroHashX providing the onchain service and access to liquidity needed to convert fiat into crypto with seamless smart contract execution, alongside @Shift4, and @xswap_link, with liquidity sourced from @Uniswap. Combining Mastercard’s global payments technology and Chainlink’s industry-standard infrastructure creates a secure user experience for billions 🧵

Was very excited about this thoughtful conversation with Jonathan Ehrenfeld, Head of Strategy at Swift. I think it clearly showcases the large benefits of Swift as a private key signing infrastructure, financial standards organization and network for routing key financial messages/information across the capital markets, among many other key services it already provides. It is clear to me that for our industry to go to the next stage, we need to make sure that blockchains become compatible with the existing financial system. Chainlink has a key role to play in making that happen, by simplifying the connectivity of those traditional data, payment and compliance systems into all blockchains, as well as the connectivity of those blockchains between each other. There will continue to be more and more critical data, identity, payment, compliance and other key systems to be integrated into and across blockchains securely, which I feel Chainlink is in a unique position to address in ways no other system can. You can hear my and Jon's views in the full podcast here: globalcustodian.com/podcasts…
Stablecoin regulation in the US will kick off a wave of new stablecoins in the US and all over the world. They will all need proof of reserves and cross-chain connectivity to be used as a source of payment for the growing digital asset economy and tokenized funds. Chainlink is the only platform that provides proof of reserves and cross-chain connectivity in one system. This is before we look at the need for on chain identity and the ability to use stablecoins as a form of payment with minimal friction when fulfilling compliance requirements. Chainlink will then be the only platform to provide proof of reserves, cross-chain connectivity and on-chain identity/compliance in a single system. As the complexity of blockchain transactions grows with more data, connectivity, compliance and other requirements, Chainlink will be being built as the only platform that can fulfill all those requirements in a single unified system of transactional standards. All of these Chainlink capabilities can then be easily configured, deployed and managed in one piece of workflow code on CRE. So you're getting all the services you need to prove reserves, connect across chains, solve compliance/identity issues and manage all this complexity with a single piece of code, in one system.
Very excited about this report from Visa, showcasing how Chainlink is able to solve the three biggest problems of next generation smart contracts for institutional transactions, all in one platform. 1. Providing the critical data needed to properly price the assets in the transaction and enable transfer agents. 2. Connecting multiple chains to enable the value and the data of the transaction to move across multiple chains. Powering a public chain to private chain connection in this case. 3. Enabling compliance by providing on-chain identity proofs and matching them against various policies from two different jurisdictions and regulatory frameworks. Smart contract transactions in the institutional world are complex, they require various sources of data, multiple cross-chain connections and a reliable form of on-chain identity/compliance, all of which the Chainlink standard is able to uniquely provide in one secure and reliable platform. This transaction between ANZ and Fidelity International, two existing institutional users of Chainlink, all happening within the HKMA regulatory framework which Chainlink has now been being built work within for many years. Complicated flows like this, being executed in a compliant way, is a clear sign of the unique value that Chainlink is now able to provide. As more top institutions adopt the Chainlink standard for data, connectivity and compliance, I expect that they will begin to transact with each other more frequently, as the friction for the institutions on this comprehensive transactional standard is much less than the cost of a transaction on institutions that are on various seperate standards with multiple ways of proving data, connecting chains and creating compliance. As more and more top institutions join the Chainlink standard for institutional transactions to happen on-chain, the network and the standards become more valuable to the current participants and the ones considering joining the transactional standard. Excited about seeing more of these coming up and having Chainlink power the next stage of our industry's growth through mainstream institutional adoption. visa.com.sg/content/dam/VCOM…
