The integration links custody, smart contracts, atomic settlement to enable tokenized securities primary-secondary trading.
In early March 2026, AMINA Bank AG, a FINMA-regulated Swiss digital bank with operations across Switzerland, Abu Dhabi, Hong Kong, and the EU, completed a key stage in its digital asset modernization by becoming the first regulated bank to serve as a listing sponsor on 21X, Europe’s first fully regulated distributed ledger technology (DLT) trading and settlement system that had been launched in September 2025.
This integration enables AMINA to guide issuers in listing tokenized securities for primary and secondary market transactions, and addresses a core institutional challenge in tokenization: the lack of an end-to-end pathway linking regulated custody of traditional assets (such as government bonds, corporate securities, and treasury bills) with compliant onchain issuance and liquid, regulated trading venues.
Prior efforts had enabled blockchain-based asset issuance, but no EU-supervised secondary market had existed until 21X’s operational launch. The bank subsequently implemented a three-layer technical architecture:
- Institutional-grade custody and banking services for underlying traditional assets, ensuring regulatory alignment
- Smart contract deployment with automated compliance controls (based on ERC-3643 standards) for token issuance and distribution
- Regulated DLT venue supporting smart contract–driven order matching, atomic settlement, and trading of tokenized instruments on Polygon and Stellar networks, bypassing traditional clearinghouses
This setup reduces settlement times and counterparty risks for AMINA’s clients, who can now tokenize and trade conventional financial products within frameworks equivalent to legacy markets.
The bank’s Chief Product Officer, Myles Harrison, said: “Institutional investors have rightly waited for tokenization infrastructure that meets their governance and compliance standards. By partnering with 21X … we’ve assembled the complete infrastructure — from banking custody of underlying assets through to onchain issuance and exchange trading.”
21X’s Chief Executive Officer, Max J Heinzle, commented: “With our secondary market now fully operational, the addition of a world-class institutional partner like AMINA… provides the … rigour and innovation required to scale our platform.
