Boerse Stuttgart, flatexDEGIRO, SocGen launch blockchain rails

Boerse Stuttgart’s digital settlement platform Seturion has formed a partnership with online broker flatexDEGIRO and Societe Generale, including its crypto arm SG‑FORGE, to create a pan‑European blockchain settlement network. The project aims to settle tokenized structured securities on‑chain and reduce costs for retail clients.

Under the agreement, Societe Generale will issue tokenized structured products such as turbo warrants and investment certificates through Seturion. flatexDEGIRO will route retail orders from its customer base into the on‑chain system. The partners said the digital securities will be tradable on European trading venues, including Boerse Stuttgart’s markets and Nasdaq’s European platforms, with final settlement executed on Seturion using regulated euro‑ and U.S. dollar‑pegged stablecoins supplied by SG‑FORGE.

Seturion is designed to operate across public and private blockchains to address Europe’s fragmented post‑trade infrastructure. The platform is intended to move final settlement from legacy systems to tokenized rails, with the goal of lowering settlement costs and shortening transaction cycles.

Matthias Voelkel, CEO of Boerse Stuttgart Group, described Seturion as the European settlement platform for a unified capital market and said it is offered as an open industry solution to help standardize settlement.

Lidia Kurt, CEO of Seturion, noted the initial focus will be tokenized structured securities because they have high transaction volumes and a large number of issued products. flatexDEGIRO serves more than 3.5 million customers across 16 countries and will provide retail flow to scale the use case.

Oliver Behrens, CEO of flatexDEGIRO, highlighted execution quality and settlement efficiency as priorities for online brokerages and described tokenization as an area of “enormous potential.” Jean‑Marc Stenger of SG‑FORGE said the collaboration connects traditional finance with the digital asset ecosystem while keeping settlement within regulated frameworks. Christian Sagerer, a member of Societe Generale’s Frankfurt branch management board, added the bank plans to use the blockchain infrastructure to change how structured securities are issued and distributed.

Seturion’s architecture is built to support multiple asset classes over time, with tokenized structured products as the first live use case. The partners say the arrangement could scale retail access to on‑chain settlement and reflects efforts by established financial institutions to modernize back‑office processes using blockchain technology and regulated stablecoins.
