Inside Seturion: Europe’s New Blockchain Settlement Network for Tokenized Securities

Europe’s financial infrastructure is slowly moving toward blockchain‑based settlement. A new partnership announced on May 21 centers on Seturion, the tokenized securities settlement platform developed by Boerse Stuttgart Group, and brings together a major bank, a regulated stablecoin issuer, and one of Europe’s largest retail brokers.

The collaboration with Société Générale, its crypto subsidiary SG‑FORGE, and online broker flatexDEGIRO aims to build a pan‑European settlement network for tokenized securities, allowing financial products to be issued, traded, and settled directly on blockchain infrastructure.

What Seturion Is

Seturion is a post‑trade settlement platform for tokenized securities developed by Boerse Stuttgart Group. It is designed as an open network that banks, brokers, and trading venues can use to settle transactions involving digital securities issued on blockchain infrastructure.

Instead of relying solely on traditional post‑trade systems, Seturion enables settlement using on‑chain assets and interoperable blockchain networks, helping connect different participants in a shared settlement layer.

The Three Core Partners and Their Roles

The partnership links three key pieces of financial market infrastructure: issuance, settlement money, and retail distribution.

Société Générale – Issuer of tokenized securities
The French banking group plans to issue tokenized structured financial products, including instruments such as turbo warrants and investment certificates, directly on the Seturion platform.

SG‑FORGE – Stablecoin settlement provider
SG‑FORGE, Société Générale’s digital‑asset subsidiary, will provide the cash leg of settlement using its CoinVertible stablecoins:

• EURCV (euro‑pegged)
• USDCV (U.S. dollar‑pegged)

These regulated stablecoins will be used to settle trades for the tokenized securities issued on the platform.

flatexDEGIRO – Retail investor distribution
The online broker connects Seturion to a large European retail investor base. flatexDEGIRO serves more than 3.5 million customers across 16 countries, potentially providing significant demand and liquidity for tokenized structured products listed on connected trading venues.

Together, the partners create a network that links issuance, settlement infrastructure, and investor access in a single blockchain‑based ecosystem.

How Tokenized Securities Would Flow Through the System

In simplified terms, a transaction in the network would look like this:

1. Issuance – Société Générale creates a tokenized structured product on the Seturion infrastructure.
2. Trading – The product can be listed and traded on connected European trading venues.
3. Broker access – Investors using brokers such as flatexDEGIRO place buy or sell orders.
4. Settlement – Seturion processes the post‑trade settlement.
5. Payment – SG‑FORGE stablecoins (EURCV or USDCV) settle the cash side of the transaction on blockchain rails.

This architecture links all stages of the securities lifecycle—from issuance to final settlement—inside a digital infrastructure.

Support for Public and Private Blockchains

One design goal of the platform is interoperability. Seturion’s architecture supports both public and selected private blockchains, allowing financial institutions to integrate existing or emerging tokenization platforms.

Settlement can occur using:

• regulated on‑chain stablecoins such as EURCV or USDCV, or
• other forms of digital settlement assets supported by the system, including potential central‑bank‑issued money where available.

This flexibility is intended to make the platform usable across multiple regulatory and technical environments in Europe.

Why Structured Securities Are the First Use Case

Structured products—such as turbo warrants or investment certificates—are widely issued and traded across European markets. Because they involve large volumes of issuances and transactions, they provide a practical starting point for testing tokenized issuance and blockchain settlement at scale.

Launching with these instruments allows market participants to measure improvements in efficiency and operational workflows compared with traditional settlement systems.

Why the Initiative Matters for Europe’s Capital Markets

European securities settlement remains fragmented across national systems and infrastructures, which can create complexity for cross‑border trading and post‑trade processes.

The Seturion initiative aims to address that fragmentation by creating a shared digital settlement layer that connects:

• banks issuing securities
• brokers distributing them to investors
• trading venues listing them
• and blockchain‑based settlement assets

If widely adopted, such a network could help streamline cross‑border settlement and support the development of a more integrated European capital market infrastructure.

The Bigger Picture

Tokenized securities have been widely discussed in finance, but most initiatives focus on either digital issuance or experimental trading platforms. The Seturion partnership stands out because it attempts to link multiple pieces of the market structure at once—issuer, settlement money, infrastructure provider, and retail distribution.

By connecting these layers on a single network, the partners are effectively testing whether blockchain can function as a full post‑trade backbone for regulated securities markets in Europe.
