What solarisbank digital assets referred to
The search term solarisbank digital assets usually points to Solaris Digital Assets GmbH, a wholly owned subsidiary announced by the then Solarisbank AG on December 11, 2019. The subsidiary was set up to provide an API-accessible custody platform for digital assets and to connect that service with Solarisbank’s white-label banking infrastructure.
That positioning placed the project between three markets: Banking-as-a-Service, crypto custody, and regulated embedded finance. It should not be read as a current product page, however. Solarisbank later became Solaris, and public company reporting for 2023 and 2024 shows that Solaris Digital Assets was wound down, its licensable operations were discontinued, and the remaining company was merged into Solaris SE.

The original model behind Solaris Digital Assets
Solarisbank’s digital asset plan was not primarily a consumer-facing crypto exchange. The stated model was infrastructure. Fintech apps, crypto platforms, brokers, tokenization projects, and similar partners could build their own customer experience while using Solaris-related regulated infrastructure in the background.
The 2019 announcement described Solaris Digital Assets as a 100% subsidiary of Solarisbank AG. Its first product was positioned as a white-label custody solution for digital assets. In practice, that meant a partner could connect through APIs, launch a customer-facing crypto or token product, and avoid building every custody, compliance, and banking component from scratch.
This matched Solarisbank’s broader Banking-as-a-Service strategy. Solaris had already built a business around accounts, payments, cards, Know Your Customer processes, and modular banking APIs. Digital asset custody was intended to extend that stack into crypto, giving partners a way to combine fiat accounts, identity verification, custody, and potentially trading-related workflows.
Custody was the central issue. Digital assets are controlled through private keys. If a private key is stolen, misused, or lost, the asset may be difficult or impossible to recover. Solaris described its planned custody architecture as using distributed hardware security modules, digital bookkeeping, validation workflows, and transaction monitoring. The aim was to balance security with instant access, a trade-off every crypto custodian has to manage.
Timeline of the Solaris digital asset project
| Date | Event | Why it mattered |
|---|---|---|
| 2018 | Solarisbank launched its Blockchain Factory initiative. | It marked Solarisbank’s early move into banking infrastructure for blockchain and crypto businesses. |
| December 11, 2019 | Solarisbank announced Solaris Digital Assets GmbH. | The subsidiary was designed to offer API-accessible digital asset custody alongside white-label banking services. |
| January 2020 | Germany’s crypto custody authorization regime became a key issue for firms storing crypto assets for customers. | Custody shifted from a technical function into a regulated financial service requiring supervisory attention. |
| September 17, 2020 | Solaris Digital Assets applied for permission to provide crypto custody business, according to Solaris reporting. | The application allowed the company to operate under German transitional provisions while the authorization process was pending. |
| July 26, 2022 | Solarisbank announced the brand change to Solaris, later reflected in its legal status as Solaris SE. | Readers should understand that older Solarisbank references and newer Solaris references often point to the same group history. |
| November 2023 | Solaris decided to wind down Solaris Digital Assets, terminate partner contracts, and submit a liquidation plan. | This changed the interpretation of the project from an active expansion story to a wind-down and restructuring story. |
| July 31, 2024 | Solaris reporting described this as the target date for completion of the regulated operational wind-down. | The timetable is important for avoiding outdated claims that the original custody platform was still expanding. |
| August 12, 2024 | Solaris’ 2024 disclosure report states that the merger of Solaris Digital Assets into Solaris SE was registered, effective January 1, 2024. | The named subsidiary became part of Solaris SE rather than continuing as a separate public-facing vehicle. |
Why the idea made sense in 2019
The Solarisbank digital assets strategy had a clear rationale in late 2019. Crypto had moved beyond a niche technical audience, but many financial apps still lacked regulated custody infrastructure. European regulators were also making clear that crypto custody could not remain in a gray zone. At the same time, many consumer-facing platforms wanted to offer crypto access without becoming full-stack custodians themselves.
For an embedded finance provider, that created a logical opening. If a platform already helped companies launch bank accounts, cards, and identity checks, custody could become another module in a wider financial stack. In theory, a fintech could combine a euro account, card, KYC flow, crypto custody, and trading access through a connected infrastructure layer.
The same logic still influences much of the institutional digital asset market. Most brands do not want to run private key infrastructure, blockchain monitoring, custody insurance arrangements, regulatory filings, and operational resilience controls on their own. They generally want a specialist provider to handle regulated back-end complexity while they manage the customer relationship.
Solaris Digital Assets was therefore an early example of a broader industry thesis: crypto adoption would depend not only on market enthusiasm, but also on reliable custody, identity, compliance, and fiat on-ramp infrastructure.
What changed by 2023 and 2024
By the time Solaris published its 2023 group accounts, the strategic picture had changed. The report said Solaris decided on November 21, 2023 to discontinue the business of Solaris Digital Assets, terminate existing partner contracts, and wind down the company. It also stated that the crypto custody authorization application was withdrawn in late November 2023 after a supervisory decision allowed residual regulated business to be provided only for wind-down purposes.
The same report linked the decision to a difficult market environment, including the crypto winter and the insolvency of Nuri GmbH. Solaris also described a wider strategic focus on profitability, partner portfolio adjustments, and core digital banking products such as accounts, payments, and cards.
Solaris’ 2024 disclosure report added a further important detail: the licensable business had been discontinued, and the remaining Solaris Digital Assets entity was merged into Solaris SE. The merger was registered on August 12, 2024 with effect from January 1, 2024. This is the key point for anyone researching the term today. The historic product idea remains relevant, but the named subsidiary should not be treated as a stand-alone growth platform based on the public reporting now available.

What it means for banks, fintechs, and crypto platforms
The Solaris case offers several practical lessons for digital asset companies and embedded finance teams.
- Licensing is not a side issue. In Germany, crypto custody became a regulated activity under BaFin supervision. Under the EU’s Markets in Crypto-Assets Regulation, crypto-asset service providers now face a more harmonized European framework.
- Custody is infrastructure, not just storage. A serious custody model includes private key management, customer authorization, transaction monitoring, reconciliation, incident response, and operational resilience.
- Partner concentration can matter. If a digital asset infrastructure provider depends on a limited number of large crypto partners, a market downturn or partner exit can change the economics quickly.
- Banking and crypto do not automatically merge cleanly. Bank-grade compliance, deposit products, fiat payments, securities brokerage, and crypto custody have different regulatory and operational requirements.
- Outdated product pages can mislead readers. Digital asset projects often change status faster than older announcements disappear from search results. Dates and annual reporting matter.
For fintech builders, the main takeaway is not that bank-linked crypto custody is impossible. It is that the business case has to withstand licensing cost, market cycles, technology risk, compliance scrutiny, and partner demand. A launch announcement is only the starting point.
How Solaris fits into the wider EU digital asset market
The wider European context has changed significantly since Solaris Digital Assets was announced. MiCA introduced a harmonized EU framework for issuers of crypto-assets and crypto-asset service providers. Stablecoin-related provisions applied from June 30, 2024, while the broader MiCA framework applied from December 30, 2024. Transitional arrangements for some existing providers could run until July 1, 2026, depending on national implementation and authorization status.
That regulatory shift makes the Solaris story more instructive. In 2019, national regimes were still taking shape. By 2026, the European crypto market is more clearly divided between authorized providers, firms operating under specific exemptions, and firms that must restructure or exit certain activities. Custody providers also face growing expectations around operational resilience, cybersecurity, governance, outsourcing, and customer asset protection.
From an editorial perspective, solarisbank digital assets is best understood as a case study in the shift from early crypto infrastructure experimentation to regulated, capital-intensive financial infrastructure. The original vision was to help partners offer compliant digital asset services through APIs. The later wind-down shows how difficult that model can be when market conditions, licensing demands, and partner economics change.
