flatexDEGIRO, Societe Generale, and SG-FORGE join Seturion, Boerse Stuttgart Group’s European settlement platform for tokenized securities

Media release

Stuttgart, Germany, 21 May 2026

A landmark collaboration aims to establish the pan-European industry solution for digital blockchain-based securities settlement, driving efficiency and supporting the development of a unified European capital market, bringing together:

• Seturion, the European settlement platform of Boerse Stuttgart Group, one of Europe’s leading exchange groups, will provide settlement for transactions between the parties
• flatexDEGIRO, one of Europe’s fastest‑growing online brokers, will connect the platform to its European retail flow for tokenized securities
• Societe Generale, a European market leader in structured securities, aims to issue a tokenized version of the products on Seturion
• Societe Generale-FORGE (“SG-FORGE”), the Group’s crypto-asset subsidiary and the first MiCA-compliant stablecoin issuer supported by a major European bank, will provide its Euro and US dollar stablecoins for settlement

Seturion, Boerse Stuttgart Group’s European settlement platform for tokenized securities, today announced a strategic partnership with flatexDEGIRO, Societe Generale, and SG-FORGE, on a clear path to expand its network of leading financial institutions across Europe and to advance digital blockchain-based securities settlement.

Boerse Stuttgart Group has created Seturion as a pan-European industry solution that is open to all market participants – banks, brokers and trading venues can connect easily. While tokenized structured securities will be one of the first asset classes to scale rapidly on Seturion, the platform will support all asset classes on public and private blockchains, as well as settlement against on chain money – such as MiCA-compliant stablecoins – and central bank money. Besides the trading venues of Boerse Stuttgart Group, Nasdaq’s European trading venues will connect to Seturion to facilitate trading of tokenized securities settled through the platform. By using Seturion, banks and brokers will benefit from significantly lower settlement costs and higher efficiency across European markets.

As a European market leader in structured securities, for example turbo warrants and investment certificates, Societe Generale intends to issue tokenized structured securities via Seturion as part of this new partnership. These instruments are planned to be listed and traded on European trading venues connected to Seturion for settlement.

flatexDEGIRO is one of Europe’s fastest growing online brokers, serving more than 3.5 million customers across 16 countries. Societe Generale is already a well‑established partner of flatexDEGIRO in the trading of structured securities across its markets. Trading venues connected to Seturion will therefore benefit from access to flatexDEGIRO’s European retail investor flow in Societe Generale’s tokenized structured securities.

Settlement of transactions between the parties involved shall be carried out by Seturion using CoinVertible, the Euro and US dollar pegged stablecoins issued by SG-FORGE.

Dr. Matthias Voelkel, CEO of Boerse Stuttgart Group, said: “With Seturion, we are building the European settlement platform for the unified European capital market that is emerging as a result of the Capital Markets Union. As an open industry solution, Seturion contributes to overcoming Europe’s fragmented settlement landscape. We are delighted to welcome industry leaders such as flatexDEGIRO, Societe Generale and SG-FORGE as our strategic partners. More leading financial institutions will follow.”

Dr. Lidia Kurt, CEO of Seturion, said: “Faster and more cost-efficient settlement on tokenized rails is especially relevant for securities with high numbers of transactions and issued products. That is why tokenized structured securities will be one of the first asset classes to scale rapidly on Seturion. But others will follow – Seturion covers all asset classes. Our partnership with flatexDEGIRO, Societe Generale and SG-FORGE is an important step, as it demonstrates the huge benefits for buy-side and sell-side with significantly lower costs, high reliability and shorter settlement cycles.”

Oliver Behrens, CEO of flatexDEGIRO, said: “Execution quality and efficiency of settlement are crucial benefits in online brokerage and customers have high expectations from a leading European trading platform such as flatexDEGIRO. The tokenization of securities has enormous potential in this area, and we are excited to be working with other strong partners at the forefront to drive forward this pioneering development.”

Christian Sagerer, Member of the Management Board of Societe Generale Frankfurt Branch, said: “As a leading European issuer of structured securities, Societe Generale is committed to drive innovation in capital markets. Through this partnership, we plan to leverage tokenization and blockchain-based infrastructure to enhance efficiency in issuance and distribution, while delivering innovative solutions that support our clients’ growth and contribute to the modernization of financial market infrastructures.”

Jean-Marc Stenger, CEO of Societe Generale-FORGE, said: “As a regulated stablecoin issuer, SG‑FORGE plays a pivotal role in advancing blockchain‑based market infrastructure, building a bridge between digital-asset ecosystem and traditional finance in line with our mission. By enabling secure and on‑chain settlement through reference MiCA-compliant stablecoins, we act as a key enabler for delivering efficiency gains through this new partnership.”
