What the ECB launched on September 21

The European Central Bank confirmed that the initial launch of Pontes took place on September 21. The service connects market-operated distributed ledger technology (DLT) platforms with TARGET Services, the infrastructure the Eurosystem already uses for large-value payments and securities settlement.

DLT is the broader category that includes blockchains. Under the new arrangement, a bank, central securities depository or regulated trading venue can record a tokenized bond or another financial asset on its own ledger, while Pontes provides a route for the corresponding euro payment to reach Eurosystem infrastructure.

The term “blockchain bridge” is therefore shorthand. The ECB has not created another public blockchain or moved participating institutions onto a single shared ledger. Instead, Pontes links existing market systems to central-bank settlement. Assets can remain on their existing ledgers, while the cash leg can settle in central bank money.

The ECB’s official information on Pontes is available here.

How a tokenized trade settles through Pontes

Consider a bank purchasing a tokenized bond. The bond may be recorded on a market-operated ledger, while the buyer’s funds are held elsewhere. The settlement challenge is to exchange both safely: the buyer should not pay without receiving the bond, and the seller should not deliver the bond without receiving the money.

The process has three parts:

1. Asset: The tokenized security is delivered on the market’s DLT platform.
2. Payment: The buyer pays with a Eurosystem cash token or through T2.
3. Coordination: Hash-Link is designed to coordinate delivery and payment on an all-or-none basis.

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, the Eurosystem’s 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 is completed there.

Hash-Link supplies the coordination required for delivery versus payment, commonly shortened to DvP. The asset and the money do not need to be recorded on the same ledger; the protocol is intended to make the two transfers function as a single exchange.

Why central bank money matters

Commercial-bank money carries the credit risk of the bank holding the funds. A stablecoin, meanwhile, 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 broader payments strategy continues to allow private settlement assets, including tokenized deposits and regulated stablecoins, while keeping central bank money at the foundation of interbank settlement. The ECB has outlined that wider strategy here.

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 requirements behind that result. Platforms must align transaction identifiers, time limits, failure procedures and responsibility when one leg of a transaction cannot be completed.

Access begins with banks and regulated market operators

Ordinary crypto wallets cannot connect to Pontes. Initial eligibility rules cover entities with T2 access and regulated operators, including 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. Reuters’ report is available here.

Clearstream had already announced end-to-end testing covering connectivity, transaction processes and operational readiness. Its announcement is available here. Such testing provides more information 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

Pontes addresses a specific problem: providing eligible DLT markets with access to a trusted cash leg. It does not make different ledgers, token standards or legal frameworks compatible. Institutions may obtain safer payment finality while still having to connect with several platforms.

The ECB’s exploratory work identified potential benefits from automation and from bringing issuance, trading, settlement and custody closer together. Lower costs and faster processing are not automatic, however. They depend on sustained transaction volume, common standards and how often an exception still requires manual intervention.

That 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.

Activity will show whether institutions return

Trading infrastructure is also developing outside the banking system. Uniswap, for example, supports restricted tokenized markets and has expanded onto Circle’s Arc network, as reported in Coindoo’s coverage. Pontes addresses a different layer of the same market: how regulated institutions complete the cash side of a tokenized transaction in central bank money.

Three indicators will be relevant:

• Repeat volume: One-off trials show that a connection works; recurring transactions show whether institutions use it on an ongoing basis.
• 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 number of technical integrations.

Onboarding numbers will show whether institutions can connect. Repeat transactions will show whether they have a reason to remain connected. Pontes can provide the central-bank cash leg that tokenized markets require, but it cannot create demand for the securities being exchanged.
