On March 9, AMINA Bank AG announced it has become a listing sponsor on 21X, making it the first regulated bank to join the venue in that role. Under the arrangement, AMINA will provide custody and banking for underlying assets and support issuers bringing tokenized financial instruments to market on 21X, while Tokeny supplies the tokenization layer for issuance and compliance workflows. The setup links a Swiss-regulated bank, an on-chain issuance platform, and an EU-regulated distributed-ledger trading and settlement venue in a single operating chain.
The regulatory framework behind 21X
The venue operates inside the EU's DLT Pilot Regime. 21X says BaFin granted it a DLT trading and settlement system licence in December 2024 under Regulation (EU) 2022/858, positioning it as the first fully regulated blockchain-based trading venue of its kind in the EU. ESMA's review of the pilot regime identifies 21X AG as an authorised DLT TSS and confirms that ESMA issued a positive opinion on the exemptions sought for the infrastructure. AMINA's new role does not create a new regulatory framework — it adds a regulated bank participant to an already supervised market structure.
What listing sponsors actually do
The distinction matters operationally. 21X's own service materials describe listing sponsors as handling onboarding, due diligence, and sponsored access for issuers and asset managers, while the venue itself provides listing, trading, registry, and atomic settlement functions on-chain. AMINA and Tokeny had already announced a cooperation in October 2025 covering regulated banking, custody, and tokenization for bonds, corporate securities, and treasury bills. The new step moves that earlier relationship into a regulated secondary-market environment, rather than keeping it as a standalone tokenization workflow.
The announcement is also distinct from earlier 21X milestones: Apex Group was named the venue's first listing sponsor in May 2025, while AMINA is specifically identified as the first regulated bank to take on that function. For issuers, the practical change is that a regulated bank is now available within the 21X framework for listing-sponsor activity alongside custody and banking. For investors, access remains tied to the venue's permissioned and regulated structure under the EU pilot regime, as reflected in ESMA's current registry. Neither AMINA nor 21X identified a first issuer, specific asset, or real-estate-backed instrument in the announcement.
