Boerse Stuttgart Group announced on May 21, 2026, that its tokenized settlement platform Seturion has signed on Societe Generale, the bank's digital assets unit SG-FORGE, and the online broker and banking group flatexDEGIRO as new partners. The additions expand a network that now spans institutional issuers, a regulated stablecoin settlement layer, and a retail distribution base of more than 3.5 million customers across 16 European countries.

How the Network Divides Its Labor

Each new partner fills a distinct role. Societe Generale will issue tokenized structured securities, specifically certificates and warrants, through the Seturion network. SG-FORGE will handle settlement using its CoinVertible stablecoins: EURCV (euro-backed) and USDCV (dollar-backed). Both tokens are classified as e-money tokens under the EU's MiCA regulation (Markets in Crypto-Assets Regulation) and have been compliant since the stablecoin provisions took effect on July 1, 2024. CoinVertible is regulated by France's ACPR (Autorité de Contrôle Prudentiel et de Résolution). flatexDEGIRO, formed from the 2020 merger of Germany's flatex bank and the Dutch discount broker DEGIRO, connects the network to retail order flow.

SG-FORGE has been issuing tokenized bonds and securities since 2019, establishing the firm as an experienced participant in digital asset infrastructure rather than a newcomer to the space.

SG-FORGE CEO Jean-Marc Stenger said in a statement: "As a regulated stablecoin issuer, SG-FORGE plays a pivotal role in advancing blockchain-based market infrastructure."

flatexDEGIRO CEO Oliver Behrens pointed to faster settlement as the central opportunity: "Tokenization of securities has enormous potential, with faster settlement as a key focus."

What Seturion Is and Why Settlement Speed Matters

Seturion launched commercially in September 2025. It is built to address Europe's post-trade fragmentation, where member states maintain separate national securities depositories that do not easily interoperate. Legacy settlement across European markets typically runs on multi-day cycles; under the EU's Central Securities Depositories Regulation, equities markets operate on a T+2 standard, meaning two business days pass between a trade and its final completion.

Boerse Stuttgart claims Seturion can cut post-trade settlement costs by up to 90% compared with existing infrastructure.

The platform participated in the European Central Bank's 2024 wholesale DLT settlement trials, where it demonstrated settlement finality in minutes rather than days. It currently operates at BX Digital, a Swiss trading venue licensed by the country's financial regulator FINMA, and has filed for a DLT Pilot Regime license with Germany's BaFin. The EU's DLT Pilot Regime is a regulatory sandbox that allows tokenized securities trading and settlement to proceed under supervised conditions.

Boerse Stuttgart Group CEO Dr. Matthias Voelkel described the platform's ambition in clear terms: "With Seturion, we are building the European settlement platform for the unified European capital market." In a separate statement tied to the Nasdaq integration, Voelkel added that "Seturion contributes to overcome current national settlement infrastructure silos."

Nasdaq connected its European trading venues to Seturion in March 2026, focusing initially on structured products, including certificates and warrants. Roland Chai, President of European Market Services at Nasdaq, said at the time that "tokenization presents a transformative opportunity to address inefficiencies in settlement." Seturion CEO Dr. Lidia Kurt framed the problem more bluntly: "Financial markets should no longer rely on legacy post-trade infrastructure that was not designed for a digital world."

Token Metrics and On-Chain Context

CoinVertible, which serves as one of Seturion's on-chain settlement options alongside central bank money, has seen its market capitalization grow roughly 60% in 2026 to approximately $120 million. This figure reflects CoinVertible's overall market cap across all platforms and use cases, not a Seturion-specific settlement volume metric.

The stablecoin is deployed across Ethereum, Stellar, and the XRP Ledger, with a Solana deployment planned. Its presence on Stellar and the XRP Ledger is notable: both networks carry significant payment volume in Africa-facing corridors, meaning the settlement token used inside a European regulated infrastructure already has reach in regions far outside the EU.

Seturion's architecture is blockchain-agnostic, meaning it can connect to both public and private distributed ledgers. The specific networks it supports have not been publicly disclosed.

Why This Matters Beyond Europe

Seturion is explicitly a European project, but the infrastructure choices it is making carry weight for markets struggling with similar problems elsewhere. Africa operates 27 separate securities exchanges on incompatible settlement rails, many still running T+3 or longer. Nigeria's Investments and Securities Act, signed into law in March 2025, formally recognized digital assets and crypto-tokens as securities, creating a legal basis for tokenized settlement infrastructure to operate there.

A South African tokenized bond trial saw 65.5% of a R100 million issuance taken up by retail investors, suggesting meaningful demand exists for accessible digital securities in markets outside established financial centers.

Cornell Business Review noted in April 2026 that virtually every tokenized stock currently trading is a U.S. equity, with no meaningful tokenization of emerging market securities underway.

Seturion's network model, combining a regulated issuance layer, stablecoin settlement, and retail brokerage distribution, offers a template that infrastructure builders in Africa and other fragmented markets may study and adapt, though analysts caution that translating such models to different regulatory environments requires careful local consideration.

What Comes Next

The European Commission has proposed a major upgrade to the DLT Pilot Regime that would raise the per-platform cap from 6 billion euros to 100 billion euros and allow crypto-native businesses (CASPs) to participate directly. The timing is significant: MiCA's full transitional period for CASPs runs until July 1, 2026, meaning the broader regulatory landscape for entities like CoinVertible and prospective network participants is still taking its final shape.

If that proposal passes, it would significantly expand the class of institutions that can connect to networks like Seturion. For now, the platform remains in its pre-commercial scaling phase under the existing sandbox rules, with the Societe Generale, SG-FORGE, and flatexDEGIRO integrations extending the network further since Nasdaq joined in March.
