ECB Launches Blockchain Bridge for Tokenized Bank Settlement
The ECB has launched Pontes, a bridge that lets regulated financial platforms settle tokenized trades in central bank money without moving the assets onto an ECB blockchain.
What changed
- Market DLT platforms have a live connection to TARGET Services.
- The cash leg can settle in central bank money.
- Assets can remain on their existing ledgers.
What stayed the same
- Access remains limited to eligible institutions.
- The ECB has not created a shared public blockchain.
- Each market still controls its own asset infrastructure.
What the ECB launched on September 21
The European Central Bank confirmed that the initial launch of Pontes took place on September 21. It connects market-operated distributed ledger technology platforms with TARGET Services, the infrastructure the Eurosystem already uses for large-value payments and securities settlement.
Distributed ledger technology, or DLT, is the broader category that includes blockchains. A bank, central securities depository or regulated trading venue can record a tokenized bond or another financial asset on its own ledger. The new service supplies a route for the corresponding euro payment to reach Eurosystem infrastructure.
The headline description “blockchain bridge” is therefore shorthand. The ECB has not launched another public chain or moved participating institutions onto one ledger. It has connected existing market systems to central-bank settlement.
How a tokenized trade settles through Pontes
Consider a bank buying a tokenized bond. The bond may sit on a market-operated ledger, while the buyer’s money is held elsewhere. The challenge is to exchange both safely: the buyer should not pay without receiving the bond, and the seller should not surrender it without receiving the money.
Two routes for the cash leg
The ECB describes a dual settlement model. Participants can use cash tokens on a Eurosystem DLT platform or send the payment through T2, its real-time gross settlement system for large transfers between central and commercial banks. When T2 is used, the cash leg becomes legally final once the transfer completes there.
Hash-Link provides the coordination needed for delivery versus payment, usually shortened to DvP. The asset and money do not have to sit on the same ledger; the protocol is intended to make the two transfers behave like a single exchange.
Why central bank money matters
Commercial-bank money carries the credit risk of the bank holding the funds, while a stablecoin depends on a private issuer’s reserves, redemption process and legal structure. Central bank money is a direct liability of the central bank. Using it removes commercial-bank credit risk from the final cash leg, although operational, legal and market risks remain.
Pontes is therefore neither a stablecoin nor the consumer digital euro being developed for everyday purchases. It is a wholesale service for eligible financial institutions. The Eurosystem’s wider payments strategy still allows private settlement assets, including tokenized deposits and regulated stablecoins, while keeping central bank money at the foundation of interbank settlement.
The bridge grew out of €1.6 billion in tests
The production launch follows experiments conducted between May and November 2024. According to the Eurosystem’s official report, the programme tested three central-bank solutions across securities and payment use cases.
The work covered digital bonds, automated wholesale payments and transactions involving more than one currency. It tested the Bundesbank’s Trigger Solution, Banque de France’s DL3S platform and Banca d’Italia’s TIPS Hash-Link system. The live service incorporates features examined during those separate experiments.
The trials established that separate ledgers can coordinate all-or-none transactions. They also exposed the operational work behind that result: platforms must align transaction identifiers, time limits, failure procedures and responsibility when one leg cannot complete.
Access begins with banks and regulated market operators
Ordinary crypto wallets cannot connect. The initial eligibility rules cover entities with T2 access and regulated operators such as central securities depositories, authorized DLT trading and settlement systems, supervised payment systems, central counterparties, credit institutions and investment firms.
Reuters reported that Deutsche Bank, Santander and Clearstream were among the first institutions to complete onboarding. Initial operating hours run from 08:00 to 16:00 CET on business days and are expected to expand.
Clearstream had already announced end-to-end testing covering connectivity, transaction processes and operational readiness. That is more useful than a demonstration transfer, but onboarding alone cannot establish whether institutions will bring recurring business to the system.
Pontes is the bridge; Appia is the larger redesign
The service solves a specific problem: giving eligible DLT markets access to a trusted cash leg. It does not make different ledgers, token standards or legal frameworks compatible. Institutions may gain safer payment finality while still paying to connect with several platforms.
The ECB’s exploratory work identified potential benefits from automation and bringing issuance, trading, settlement and custody closer together. Lower costs and faster processing are not automatic, however. They depend on sustained volume, common standards and how often an exception still requires manual repair.
This is why the ECB’s two-track strategy also includes Appia. Pontes links infrastructure that already exists. Appia examines whether Europe should eventually build a more integrated framework for issuing, trading, holding and settling tokenized assets.
Three figures will reveal whether institutions return
Trading infrastructure is already developing outside the banking system. Uniswap, for example, supports restricted tokenized markets and has expanded onto Circle’s Arc network, as covered in our analysis of its latest deployment. Pontes addresses a different layer of the same market: how regulated institutions complete the cash side of a tokenized transaction in central bank money.
- Repeat volume: One-off trials show that a connection works; recurring transactions show that institutions find it useful.
- Operational expansion: Longer service hours and fewer manual interventions would indicate that the bridge is moving beyond a limited launch.
- Market depth: More secondary trading in assets settled through Pontes would matter more than a rising count of technical integrations.
Onboarding numbers will show whether institutions can connect. Repeat transactions will show whether they have a reason to stay. Pontes can provide the central-bank cash leg that tokenized markets need, but it cannot create demand for the securities being exchanged.

That's probably why he hasn't stopped.
