Taurus Group: Switzerland's DLT Infrastructure Champion

Taurus Group is the most important independent DLT infrastructure company in Switzerland’s institutional digital asset ecosystem. Founded in Geneva in 2018, Taurus has built the dual-product suite that Swiss and international banks require to participate in digital asset markets: PROTECT for institutional-grade custody of crypto and tokenised assets, and EXPLORER for the issuance, management, and transfer of tokenised securities. As of 2025, Taurus serves multiple Swiss cantonal banks, international financial institutions, and has attracted strategic investment from SIX Group — Switzerland’s financial market infrastructure operator — cementing its position as a cornerstone of the Swiss DLT stack.

Founding and Leadership

Taurus was founded in 2018 by Lamine Brahimi, a former UBS wealth management executive, and Jean-Philippe Aumasson, a cryptographer of international standing. Aumasson’s credentials are unusual in a financial technology context: he holds a PhD in cryptography, has published over 70 peer-reviewed papers, and is the author of several widely adopted cryptographic standards including the BLAKE2 hash function. His involvement gave Taurus immediate credibility in the cryptographic security dimension of its custody product — a dimension that institutional clients evaluate with extreme rigour.

The founding thesis was clear: banks needed institutional-grade infrastructure for digital assets that was built specifically for their regulatory and operational requirements, not adapted from retail cryptocurrency technology. The retail crypto infrastructure of 2018 — hardware wallets, hot wallets, exchange custodianship — was manifestly unsuitable for regulated financial institutions that require multi-signatory governance, segregated client accounts, regulatory reporting, and board-level oversight of key management processes.

Brahimi’s banking industry relationships provided the initial client development path; Aumasson’s cryptographic expertise provided the technical foundation. The combination proved exceptionally effective in convincing banks that Taurus was a credible infrastructure counterparty.

The Two-Product Architecture

PROTECT: Institutional Digital Asset Custody

PROTECT is Taurus’s custody platform, designed to enable regulated financial institutions to safely store and manage digital assets — both cryptocurrencies and tokenised securities — in compliance with FINMA requirements and applicable international regulatory standards.

PROTECT’s core technical architecture centres on three custody mechanisms:

Multi-Party Computation (MPC): MPC distributes the cryptographic key required to authorise transactions across multiple parties or hardware components, ensuring that no single point of compromise can result in unauthorised asset movement. Unlike traditional multi-signature schemes (which create on-chain transaction overhead and expose the signature structure publicly), MPC key shares appear as ordinary single-key signatures on-chain while maintaining multi-party governance off-chain.

Hardware Security Module (HSM) integration: PROTECT integrates with FIPS 140-2 Level 3 certified HSMs for the highest-security key storage available in commercial hardware. HSMs are the standard for private key protection in traditional financial market infrastructure (banks, payment schemes, card networks use HSMs for payment key management); Taurus’s HSM integration extends this established approach to digital asset custody.

Policy engine and governance workflows: institutional custody is not only a technical problem — it is an operational governance problem. PROTECT includes a configurable policy engine that implements approval workflows (e.g., transactions above CHF 1 million require two authorised signatories from two different geographic locations), time-lock rules, whitelist management, and comprehensive audit logging compatible with external auditor requirements.

PROTECT holds a FINMA financial intermediary registration, allowing it to be used by FINMA-supervised institutions as a regulated custody solution rather than a self-arranged technical service.

EXPLORER: DLT Tokenisation Platform

EXPLORER is Taurus’s tokenisation platform — the interface through which banks can issue, manage, and transfer tokenised assets. Where PROTECT is the vault, EXPLORER is the issuance desk and registry manager.

EXPLORER’s capabilities include:

Tokenised security issuance: banks and financial institutions can use EXPLORER to create Registerwertrechte under Swiss DLT Act, issuing digital bonds, fund units, equity tokens, or structured product tokens without requiring SDX participation. This decentralised issuance capability is significant: it means Swiss banks can tokenise assets within their own client universe without involving a third-party exchange or CSD.

Investor register management: EXPLORER maintains the investor register for tokenised assets, including know-your-customer records, beneficial ownership tracking, and shareholder/bondholder communication. The register function is what makes EXPLORER a quasi-CSD for bank-issued tokenised securities.

Corporate actions: coupon payments, dividend distributions, capital reductions, and other corporate actions on tokenised assets can be managed through EXPLORER, triggering on-chain events (token distributions, redemptions) based on issuer instructions.

Cross-chain compatibility: EXPLORER supports multiple DLT networks, including private Corda networks, Ethereum (public and private), Hyperledger Besu, and proprietary chains, allowing issuers to choose their technical settlement layer while Taurus provides the regulatory and governance overlay.

Client Base and Market Position

Taurus’s institutional client base has been disclosed selectively, reflecting the confidentiality expectations of institutional banking relationships. Confirmed or publicly reported clients include:

Crédit Mutuel: the French mutual bank group adopted Taurus’s PROTECT platform for digital asset custody for its institutional and private banking clients, representing one of the largest banking groups (by assets under management in France) to deploy institutional crypto custody infrastructure.

CACEIS: the fund services subsidiary of Crédit Agricole and Santander, providing custody and fund administration for approximately EUR 4 trillion in assets, has engaged Taurus for digital asset custody capability development.

Arab Bank Switzerland (Geneva): the Swiss subsidiary of the Amman-headquartered Arab Bank Group deployed PROTECT for digital asset custody services for its private banking client base.

Swiss cantonal banks: multiple cantonal banks — which collectively serve the Swiss retail and SME banking market across Switzerland’s 26 cantons — have adopted Taurus infrastructure for digital asset custody and tokenisation services. Cantonal bank adoption is strategically important: it represents the Swiss financial establishment’s endorsement of Taurus as infrastructure.

International banks: Taurus has disclosed relationships with institutions in France, Germany, and the Middle East beyond CACEIS and Crédit Mutuel, reflecting its international expansion strategy.

The client profile is notably different from Fireblocks, the US-based digital asset infrastructure provider that is the global leader by client count (500+ institutional clients). Fireblocks serves a broad range from large digital asset native firms and crypto exchanges to banks; Taurus is more narrowly focused on regulated financial institutions — banks, custodians, asset managers — who require FINMA-grade regulatory positioning.

The SIX Group Investment: Strategic Validation

In 2023, SIX Group — the operator of SIX Swiss Exchange, SIX SIS (Switzerland’s traditional CSD), and SIX Digital Exchange — made a significant minority strategic investment in Taurus Group. The investment amount has not been publicly disclosed but is understood to be in the range that constitutes a meaningful minority stake, following Taurus’s Series B fundraising.

The SIX Group investment is qualitatively significant beyond its financial value:

Ecosystem integration: SIX Group’s investment creates the conditions for Taurus EXPLORE to interface more deeply with SDX’s infrastructure. A Swiss bank that uses Taurus PROTECT for custody and EXPLORER for tokenisation could potentially connect its EXPLORER-issued Registerwertrechte to SDX’s CSD for secondary market trading — a vertically integrated Swiss tokenisation stack.

Regulatory endorsement signal: when Switzerland’s national financial market infrastructure operator invests in a DLT custody and tokenisation company, it sends an unambiguous signal to FINMA-supervised banks that Taurus is the infrastructure standard-bearer for Swiss regulated digital asset activity.

Competitive positioning: the SIX investment effectively endorses Taurus as the preferred Swiss DLT infrastructure layer, distinguishing it from competitors including Custodigit (partially SIX-owned separately) and international providers like Fireblocks or Anchorage.

Prior to the SIX investment, Taurus had completed a CHF 65 million Series B in 2022, with Credit Suisse as lead investor — a round that became complicated by Credit Suisse’s subsequent collapse and acquisition by UBS in March 2023. Despite this disturbance, Taurus maintained its capital position and client relationships, and the SIX investment effectively replaced Credit Suisse as the Swiss establishment anchor investor.

Comparison with Metaco, Fireblocks, and Securitize

Taurus occupies a distinct positioning in the global institutional digital asset infrastructure market:

Metaco (now Ripple-owned): Metaco was Taurus’s closest Swiss peer — both were Geneva-area institutional custody providers targeting banks. Metaco’s HARMONIZE platform had a similar institutional client profile (Standard Chartered, BBVA, DZ Bank, Société Générale). Ripple’s acquisition in June 2023 for approximately $250 million removed Metaco from the Swiss competitive landscape and handed Taurus the position of Switzerland’s dominant independent institutional custody provider. Taurus is likely the primary beneficiary of Metaco-adjacent relationships that now prefer to maintain Swiss, FINMA-proximate custody infrastructure.

Fireblocks: the US-based market leader in digital asset infrastructure has 500+ institutional clients globally and a US venture-backed growth model. Fireblocks serves a broader client spectrum and has a stronger position in the US and in crypto-native institutional clients. In Switzerland, Fireblocks operates but does not have the FINMA-proximate regulatory positioning or Swiss financial establishment relationships that Taurus has cultivated. For Swiss-regulated banks, Taurus is typically the preferred choice.

Securitize: a US-focused tokenisation platform (acquired BlackRock’s tokenised money market fund issuance mandate for the BUIDL token) that competes in the issuance and investor register segment where Taurus EXPLORER operates. Securitize is more prominent in the US and for US-registered securities; Taurus EXPLORER is the European and Swiss standard.

International Expansion: MEA and Beyond

Taurus has pursued geographic expansion beyond Switzerland with particular focus on the Middle East and Africa (MEA):

ADGM and DIFC presence: Taurus has established a presence in Abu Dhabi Global Market (ADGM) and the Dubai International Financial Centre (DIFC), positioning it to serve the GCC (Gulf Cooperation Council) banking sector’s growing digital asset custody and tokenisation requirements. Several large Saudi, Emirati, and Qatari banks have initiated digital asset programmes and require institutional-grade infrastructure providers with regulatory credibility.

France and Germany: Taurus’s Crédit Mutuel and CACEIS relationships reflect a broader European financial institution market, served from the Geneva headquarters.

Asia exploration: Taurus has engaged with Asian financial institutions and regulatory sandboxes, though its Asian expansion is less advanced than Sygnum’s Singapore presence.

Funding and Financial Position

Taurus’s funding history:

• Seed / Series A (2018–2020): angel and early institutional investment totalling approximately CHF 10–15 million, including from Swiss banking industry participants
• Series B (2022): CHF 65 million round led by Credit Suisse (complicated by Credit Suisse’s 2023 collapse and UBS acquisition), with participation from Arab Bank, Helvetia, and other strategic investors
• SIX Group strategic investment (2023): minority stake of undisclosed amount; estimated CHF 20–40 million based on comparable transactions

Total funding: approximately CHF 85–100 million, making Taurus one of the best-capitalised independent Swiss DLT infrastructure companies.

Outlook: The Swiss Banking Industry’s Digital Asset Backbone

Taurus Group’s trajectory positions it as the closest equivalent Switzerland has to a national digital asset infrastructure champion — analogous in some respects to what SIX Group is for traditional financial market infrastructure. The combination of Swiss regulatory credibility, SIX Group strategic investment, cantonal bank adoption, international client relationships, and the competitive vacuum created by Metaco’s acquisition creates conditions for Taurus to become the de facto standard for Swiss bank digital asset infrastructure.

The key strategic question for Taurus in 2025 and beyond is international scale: can it compete with Fireblocks for European bank mandates, or will its advantage remain primarily in the Swiss and Swiss-adjacent market? If Taurus can convert MEA momentum into significant Middle Eastern bank client wins, its position as a global institutional digital asset infrastructure provider becomes significantly more credible.
