Reed Smith Rolls Out Aquarius Platform to Support EU MiCA Compliance

Reed Smith, the global law firm with more than 30 offices across North America, Europe and Asia, has introduced an automated compliance platform aimed at helping crypto firms prepare for the European Union’s Markets in Crypto-Assets (MiCA) regime as oversight intensifies. The tool, called “Aquarius,” is designed to streamline parts of the MiCA workload while keeping legal review integrated into the process.

Reed Smith says Aquarius can automate tasks such as crypto-asset classification, regulatory white paper generation, due diligence workflows and environmental, social and governance (ESG) disclosures. The firm also plans to extend the platform to other compliance environments beyond the EU, including the United Kingdom, the United Arab Emirates, Hong Kong and Singapore.

Key takeaways

• Reed Smith’s Aquarius platform targets MiCA implementation by automating classification, documentation, due diligence and ESG disclosures.


• The rollout comes as the EU moves deeper into full MiCA enforcement following the end of the July 1 transition period.


• Even with harmonized rules, authorization and ongoing supervision—especially for custodians—remain operationally demanding.


• Policymakers are also discussing possible changes to MiCA’s stablecoin framework, including rules for non-euro-denominated issuers.

Aquarius aims to reduce compliance friction as MiCA matures

MiCA is intended to create a consistent licensing and rulebook for digital asset service providers across the EU’s 27 member states, covering areas such as consumer protection and operational requirements. Reed Smith’s stated goal with Aquarius is to make entry into the European market—or expansion within it—more manageable by combining automated workflows with legal expertise.

The timing is notable. Earlier this month, the EU’s MiCA transition period ended on July 1, after which firms could no longer rely on temporary national exemptions tied to countries that had previously adopted longer grandfathering arrangements. For companies that had planned compliance in phases, the end of that window effectively tightened the deadline pressure and increased the urgency to demonstrate readiness under the full framework.

For operators, this matters because MiCA compliance is not a one-time checkbox. Firms must be able to show they meet licensing criteria and operational expectations, and they must be prepared for ongoing regulatory attention as supervisory activities ramp up.

MiCA authorization is only the start for custodians

Even though MiCA harmonizes the regulatory landscape, authorization still appears challenging for many service providers. Last week, the European Securities and Markets Authority (ESMA) launched a supervisory review of authorized crypto-asset service providers. According to earlier reporting referenced in the source material, ESMA’s focus includes how custodians safeguard client assets and how they manage operational risks.

That emphasis aligns with industry concerns around the practical burden of compliance. Sebastien Dessimoz, co-founder and managing partner of Taurus (a digital asset infrastructure provider), is cited as saying that a MiCA license is “only the beginning” for custodians. He points to continued scrutiny over cybersecurity, governance and the ability to protect client assets—issues that do not end at the moment a firm receives authorization.

In other words, compliance strategy increasingly becomes a continual operational process: firms must maintain controls, demonstrate effectiveness over time and ensure that risk management keeps pace with both technology and regulatory expectations.

Potential stablecoin rule revisions add uncertainty for issuers

Beyond licensing, the regulatory picture may be shifting for specific segments of the market. Reports suggest that EU policymakers are considering revisions to MiCA’s stablecoin framework, particularly rules governing the issuance of stablecoins that are not denominated in euros.

As cited in the source material, Euronews attributes part of the impetus for the discussions to the United States’ GENIUS Act, which created a federal framework for payment stablecoins. While the details of any EU changes were not specified in the source excerpt, the implication for market participants is clear: stablecoin issuers may need to plan for evolving requirements, especially where cross-border regulatory influence could reshape how issuers are classified and supervised.

For companies preparing documentation, disclosures or product roadmaps, this type of policy uncertainty can materially affect timelines and internal sign-offs—particularly if compliance artifacts must be updated to reflect shifting interpretations or amended standards.

Why automated compliance tools are gaining attention

Reed Smith positions Aquarius as a way to combine standardized processes with legal oversight, targeting repetitive and documentation-heavy steps that can slow down onboarding and expansion. If implemented effectively, automation could help reduce time-to-readiness by making it easier for firms to assemble core compliance outputs—such as classification materials, regulatory white paper drafts, and due diligence documentation—before legal teams finalize and validate them.

At the same time, automation does not eliminate the underlying regulatory obligations. The ESMA supervisory review referenced in the source underscores that regulators are looking beyond initial submissions to real-world custody practices, operational controls and risk management behavior.

Readers should watch how platforms like Aquarius are used in practice: whether firms treat automation as a way to build defensible compliance packages and then continuously monitor operations, or whether they simply accelerate paperwork without improving the controls supervisors expect.

As MiCA supervision expands and stablecoin-specific discussions continue, the next phase of compliance will likely be defined by two tracks: ongoing custody and operational scrutiny from regulators, and potential adjustments to stablecoin rules that could ripple into disclosures and product structures. Firms should monitor both developments while validating that their compliance systems can adapt quickly as requirements evolve.
