BX Digital and SIX Digital Exchange Differ in Technology, Settlement, and Regulatory Framework
Digital venture BX Digital manages to secure five primary investors for the debut of their Swiss blockchain trading platform.
BX Digital, a subsidiary of Boerse Stuttgart Group, and SIX Digital Exchange (SDX) are two significant players in the digital asset trading landscape, each offering unique approaches to technology, settlement, and regulatory framework.
Technology & Trading
BX Digital employs a traditional trading system off-chain for executing trades, but integrates blockchain technology for settlement. The core of its settlement infrastructure is an Ethereum blockchain-based delivery versus payment (DvP) smart contract, which enables direct settlement of tokenized securities without traditional intermediaries [1]. In contrast, SDX operates a fully integrated digital asset trading platform with on-chain trading, clearing, and settlement, leveraging proprietary distributed ledger technology to provide real-time settlement and post-trade processing [2].
Settlement
For BX Digital, settlement is hybrid, with cash settlements using traditional banking systems, while securities settlement occurs on-chain using Ethereum smart contracts. This process is described as a DvP with an off-chain trading and settlement instruction component connecting to the blockchain execution layer [1]. SDX, on the other hand, offers end-to-end on-chain settlement, meaning both cash and securities legs settle on-chain in near real-time, enhancing finality and reducing counterparty risk [2].
Regulatory Framework
BX Digital is licensed by the Swiss Financial Market Supervisory Authority (FINMA) as the first regulated DLT trading facility under the DLT Trading Facility License, effective since May 2025. It operates under the framework of the Swiss Financial Market Infrastructure Act (FinMIA) article 73d(2), targeting a regulated trading venue for digital assets that include securities and other fungible digital assets [1]. SDX, while also operating under FINMA's supervision, is typically positioned as a fully licensed digital exchange with clearing and settlement authorization, under FINMA’s oversight but with a broader scope covering issuance and custody of digital assets on-chain [2].
Summary
In essence, BX Digital uses a hybrid settlement combining traditional finance infrastructure and blockchain, focusing on accommodating existing processes. SDX aims for fully integrated on-chain trading and settlement, representing a more radical restructuring of post-trade infrastructure under the same regulatory environment but with different technological design choices [1][3].
Partnership and Launch
The launch of BX Digital's platform is a significant step in the path to creating a liquid and trustworthy ecosystem for digital assets in Switzerland. The initial five trading participants for the platform include Sygnum Bank, Incore Bank, Hypothekarbank Lenzburg, ISP Group, and EUWAX AG. These partners bring extensive experience in digital asset operations, further strengthening BX Digital's position as a leading player in Switzerland's digital finance hub [4].
Lidia Kurt, CEO of BX Digital, stated that the partnership marks a key milestone on the path to launching the trading venue [5]. The platform will enable trading of tokenized assets including shares, bonds, and funds on a public blockchain, linking directly to the Swiss National Bank's SIC payment system for settlement [6]. This new information highlights the growing institutional confidence in Switzerland's emerging tokenized finance ecosystem.
