What Happens When Swift, DTCC, and Euroclear All Use the Same Blockchain Data?

by

Swift has just completed a thrilling milestone in digital asset interoperability, all thanks to Chainlink, and it’s a blockbuster collaboration involving some of Europe‘s finest and 24 of the most illustrious global institutions, all working to overhaul capital markets infrastructure.

Ah, Swift, the proverbial architect of financial connectivity, has somehow managed to drag the otherwise tedious world of tokenized bonds into the bright lights of modernity. BNP Paribas Securities Services, Intesa Sanpaolo, and Société Générale (the FORGE crew, because of course) all took part. Let’s hope they remembered to bring their pens and calculators.

This wasn’t just any run-of-the-mill trial; no, this was an actual demonstration. They didn’t just sit around in a sandbox; they executed across live institutional infrastructure-because why settle for fake when you can have the real thing?

As @chainlink proudly shared on X, this collaboration is merely a continuation of their ever-so-successful tryst with UBS Asset Management. In fact, their earlier affair demonstrated the joys of cross-chain settlement using existing payment rails. Twelve of the world’s major financial institutions took part-Citi, BNY Mellon, BNP Paribas, and others, naturally-because if you’re going to do it, do it in style.

When 24 Banks Agree on the Same Data

At Sibos 2025, Chainlink and 24 of the largest financial institutions in the world are now announcing Phase 2 of their corporate actions processing work. Among the lucky few? Swift, DTCC, Euroclear, UBS, and Wellington Management-how utterly quaint.

In this phase, we have new roles: data attestors and data contributors. These institutions aren’t just along for the ride, oh no. They’re the ones validating and enriching the records that AI models have graciously extracted. And, marvel of marvels, data accuracy for confirmed records has reached a miraculous 100%. Truly, a triumph of human endeavor.

The Chainlink Runtime Environment has taken on the thankless task of validating multiple AI outputs. It then promptly converts these results into ISO 20022-compliant messages and pushes them onto the Swift Network. How terribly functional.

Oh, and for the icing on the cake? Chainlink’s CCIP distributed those same records across DTCC’s blockchain ecosystem, as well as other public and private chains. Multilingual disclosures-Spanish and Chinese-have been neatly included, because naturally, global compliance coverage requires multilingual flair. How else could we possibly ensure everyone’s on the same page?

The Golden Record Problem, Solved

Corporate actions data, as any connoisseur of financial bureaucracy will tell you, has always been a lovely mess. Fragmented, delayed, inconsistent across jurisdictions-an absolute delight to untangle.

But fear not! This architecture has brought forth what the initiative charmingly calls an on-chain “golden record.” A real-time data source that smart contracts, custodians, and post-trade systems can all access at once. Tokenized equities can now reference the same confirmed records, regardless of whether they exist on public or private blockchains. A true breakthrough, if ever there was one.

At Sibos 2024, as @chainlink tweeted so elegantly on X, Chainlink Co-Founder Sergey Nazarov demonstrated how banks could connect to blockchains using the existing Swift messaging standards. No need for an infrastructure overhaul. Just a bit of Chainlink’s magic sitting between the old systems and the new blockchain networks-because progress is so much easier when you don’t have to rebuild everything from scratch.

And now, this framework encompasses cross-chain settlement across institutions, including Euroclear, Clearstream, ANZ, Lloyds Banking Group, and SDX. How utterly… convenient.

GLEIF Enters the Picture

As if things weren’t exciting enough, here comes another layer-cue the fanfare! The Global Legal Entity Identifier Foundation (GLEIF) and Chainlink have teamed up to bring institutional-grade identity to the blockchain space. Why stop at just tokenized assets when you can have tokenized identities too?

GLEIF’s verifiable Legal Identity Identifier, when combined with Chainlink’s Cross-Chain Identity infrastructure and Automated Compliance Engine, allows institutions to verify asset provenance, enforce compliance policies, and recover assets if private keys are somehow compromised. A trifecta of security, compliance, and a dash of paranoia-because who doesn’t like a little extra safety?

This isn’t some “someday” dream, either. No, this framework is operational and working across jurisdictions right now. As for Swift, their global network of over 11,500 financial institutions across more than 200 countries has just confirmed that, yes, the plumbing works. They can now all join in this glorious blockchain symphony.
