Europe is taking a practical step towards bringing financial markets onchain. Euroclear and the Banque de France have launched Pythagore, a large-scale tokenization experiment involving 33 companies, including BNP Paribas, JPMorgan, Crédit Agricole, EDF, TotalEnergies and Saint-Gobain. Its first focus is the euro commercial paper market, where outstanding short-term debt is estimated at nearly €300 billion.
The project will test a security’s journey from issuance and settlement to collateral use and repayment. Euroclear, which held more than €45 trillion in assets in the first half of 2026, wants to see whether distributed ledger technology can improve processes that today remain fragmented and often rely on batch processing and repeated reconciliations. The ambition is not simply to put existing paperwork on a blockchain: it is to connect market participants and modernize how they coordinate transactions.
In brief: Pythagore brings 33 financial and corporate participants together; its first use case is euro short-term debt worth about €300 billion; the experiment links the Banque de France’s blockchain infrastructure with Euroclear’s D-FMI platform; and tests will include settlement in central bank money through Pontes, alongside a dollar stablecoin from SG-FORGE for dollar-denominated instruments.
Europe’s Pythagore project tests onchain financial markets
For newcomers, tokenization means representing a financial asset as a digital token recorded on a shared ledger. That record can support the asset’s issuance and transfer, while settlement—the exchange of the asset for payment—still depends on reliable financial infrastructure. Pythagore is designed to test these connections across the full life cycle of a security.
Why short-term debt is the first test
Companies, banks and public issuers use NEU CP, a form of short-term debt, to manage cash needs. Despite the scale of this market, its existing workflows can involve separate systems, infrequent resale and batch-based processing, making it a useful test case for whether blockchain can make transactions more coordinated.
Consider a company issuing a short-term security to cover operating costs. In a tokenized process, participants could work from a shared digital record rather than repeatedly matching information across separate systems. That does not automatically remove every delay or risk, but it gives the industry a concrete way to measure whether new infrastructure can make issuance, transfers and settlement more efficient.
How blockchain infrastructure could connect European markets
Pythagore connects the Banque de France’s blockchain infrastructure with D-FMI, Euroclear’s tokenization platform. D-FMI is built on Besu, open-source software compatible with Ethereum, a detail that matters because financial institutions are exploring different distributed ledger networks and need ways to work across them.
Fragmentation is a central concern: if each institution adopts a separate ledger with no dependable links to others, tokenized markets could become a collection of disconnected systems. Pythagore’s goal is to bring participants across the value chain into a shared experiment, a challenge also explored in broader discussions of tokenization in traditional finance.
Pontes brings central bank money into the tests
The European Central Bank’s Pontes infrastructure, officially launched on September 21, is included in the experiment. It enables eligible financial institutions to settle tokenized assets in central bank money—funds that banks hold directly with a central bank—either through TARGET, the Eurosystem’s interbank payment system, or through tokens issued on a ledger controlled by the Eurosystem.
This connection addresses a basic question for institutional markets: how can a digital security be exchanged for a form of money trusted for settlement? Using central bank money for eligible transactions can link new digital processes to a familiar monetary foundation, while supporting innovation without treating every payment token as equivalent. The Banque de France and AMF have also examined the wider challenges around tokenization and financial-market oversight.
SG-FORGE stablecoin adds a dollar-settlement use case
Not every instrument in the experiment is denominated in euros. SG-FORGE, Société Générale’s blockchain subsidiary, will test its dollar-backed stablecoin to settle dollar-denominated NEU CP, which accounts for about 5% of the market described in the project. These transactions do not fall within the same central-bank-money settlement route as euro-denominated activity.
The distinction is important: tokenization concerns the digital representation and transfer of an asset, while the payment leg may use different forms of money depending on the currency and infrastructure. Stablecoins therefore have a potential role in onchain settlement, but their use also makes questions of reserve backing, operational resilience and regulation especially relevant. Europe’s debate over private payment tokens and public money is part of the broader discussion about stablecoins and the digital euro.
What Pythagore could mean for institutional adoption
The project is an experiment, not proof that all European securities will move onto blockchain. Its significance lies in bringing banks, companies, infrastructure providers and public institutions together to test concrete processes against the demands of real financial markets.
If the tests show that issuance, settlement and collateral management can operate more smoothly across connected systems, the work could help shape future market infrastructure. For beginners, the key takeaway is simple: the promise of onchain finance depends not only on tokens, but on trusted settlement, interoperability and clear rules working together.
