Reed Smith Launches Aquarius: What the MiCA Compliance Tool Means for Accounting Firms and CFOs

A global law firm has launched an automated legal-tech platform aimed squarely at the MiCA compliance gap, and accounting firms advising digital asset clients should understand exactly what it does, what it does not do, and why its arrival matters right now. Reed Smith's new Aquarius platform targets crypto-asset service providers (CASPs) operating in or entering the EU, automating several of the most time-consuming steps in the MiCA authorisation and ongoing compliance process. For CFOs and compliance leads, this signals a maturing market where legal automation is starting to sit alongside crypto accounting software as a core infrastructure layer.

What Aquarius Actually Does

Reed Smith describes Aquarius as an automated compliance platform built specifically to help crypto companies work through the EU's Markets in Crypto-Assets regulation. The firm has identified several categories of compliance work that the platform handles.

Automated Workflow Coverage

The platform covers crypto-asset classification, which is one of the first and most consequential steps under MiCA since the classification of a token as an asset-referenced token (ART), an e-money token (EMT), or a general crypto-asset determines which licensing track and capital requirements apply. It also automates regulatory white paper generation, which MiCA mandates for most token issuers, as well as due diligence processes and environmental, social and governance disclosures. That last category is notable: ESG reporting for digital asset businesses is still an emerging area, and having it baked into an authorisation workflow rather than treated as a separate exercise is a meaningful design choice.

Reed Smith frames the platform as combining automated workflows with its own legal expertise, meaning Aquarius is positioned as a tech-assisted legal service rather than a self-serve software product. That distinction matters for accounting teams thinking about how it would interact with their own digital asset accounting software and internal controls.

Geographic Roadmap

The firm confirmed plans to extend Aquarius beyond MiCA to cover compliance regimes in the United Kingdom, the United Arab Emirates, Hong Kong, and Singapore. Given that several EU-licensed CASPs are simultaneously managing UK Financial Conduct Authority registration processes and UAE Virtual Asset Regulatory Authority requirements, a single platform spanning multiple regimes could reduce duplication of effort substantially. For multinational groups, that cross-jurisdictional scope is arguably more valuable than the EU module alone.

Why the Timing Is Deliberate

The Aquarius launch comes shortly after the EU's MiCA transition period closed for countries that had adopted the full grandfathering window. Prior to that deadline, crypto companies in certain member states could continue operating under national frameworks while MiCA authorisation was pending. That exemption is now gone. Firms that have not obtained a MiCA licence can no longer rely on transitional arrangements, and any CASP still serving EU clients without authorisation is operating outside the law.

This creates an immediate and measurable demand signal for compliance tooling. Companies that delayed their authorisation applications during the transition period are now under genuine urgency. Simultaneously, companies that did obtain authorisation are discovering that the licence is a starting point, not a finish line. Sebastien Dessimoz, co-founder and managing partner of digital asset infrastructure provider Taurus, has noted publicly that MiCA-licensed custodians face continuous scrutiny over cybersecurity practices, governance structures, and their practical ability to protect client assets on an ongoing basis.

The ESMA Supervisory Pressure Running in Parallel

Last week, the European Securities and Markets Authority launched a supervisory action examining how authorised custodians safeguard client assets and manage operational risks. ESMA's focus on custody resilience is a direct signal to the market: obtaining a MiCA licence does not mean supervisors will step back. National competent authorities across the EU's 27 member states are expected to assess CASPs against the detailed operational requirements in MiCA, and ESMA is coordinating that oversight at the pan-European level.

Implications for Accounting Firms Advising CASPs

For accounting firms and auditors working with CASP clients, the ESMA supervisory action has concrete implications. Clients holding a MiCA authorisation will face questions about their asset segregation practices, their cybersecurity incident response procedures, and whether their governance documentation matches their actual operations. These are areas where accounting and audit teams are frequently the first to identify gaps, whether during statutory audits, agreed-upon procedures engagements, or periodic compliance reviews. Firms should be reviewing client documentation against MiCA's Title V custody requirements now rather than waiting for a supervisory letter to arrive.

The intersection with the EU MiCA review consultation is also worth tracking. The European Commission is already gathering input on how MiCA should evolve, which means firms need to be advising clients on the current regulation while monitoring potential changes to asset classifications, capital requirements, and stablecoin rules in the next iteration.

Stablecoin Tensions and the GENIUS Act Backdrop

One of the more consequential developments running alongside the Aquarius launch is the reported friction between EU authorities and aspects of MiCA's stablecoin framework. Reports cited by Euronews indicate that discussions are under way about the rules governing non-euro-denominated stablecoins, with the debate partly triggered by the United States' GENIUS Act, which established a federal framework for payment stablecoins at the federal level.

MiCA currently imposes volume caps and additional requirements on EMTs denominated in currencies other than the euro. A US dollar stablecoin that exceeds the transaction thresholds set by the European Banking Authority faces restrictions on its use as a means of payment in the EU. If those rules are revisited in response to international competitive pressure, the compliance obligations for stablecoin issuers and the firms accounting for stablecoin reserves could shift materially. Accounting teams carrying stablecoin positions on client balance sheets should be tracking this closely; the Binance MiCA setback illustrated how quickly the licensing landscape can shift when regulatory conditions change.

What This Means for Accounting and Finance Teams

Reed Smith's Aquarius sits in the legal-tech layer of MiCA compliance: it handles classification, white papers, and regulatory filings. It does not replace the financial controls, transaction-level record-keeping, and reporting that accounting teams own. The two layers need to be coordinated, not conflated.

For Accounting Firms Advising CASP Clients

The key accounting and audit implications of the current MiCA environment cluster around several areas. First, token classification under MiCA is not just a legal question; it determines how a token is recognised on the issuer's balance sheet, what reserve assets must be held, and how those assets are measured. An ART issuer must maintain a reserve of assets backing the token's value, and the composition and measurement of that reserve is an accounting matter as much as a legal one. Auditors signing off on ART issuers need to understand MiCA's reserve requirements and how they map to applicable accounting standards.

Second, the white paper requirement creates a disclosure document that contains financial and operational commitments. If the white paper states specific liquidity ratios, redemption timelines, or fee structures, those commitments become relevant to the audit of the issuer's financial statements. Any digital asset accounting software used by the client needs to produce data at the granularity required to verify compliance with white paper disclosures.

Third, the ESG disclosure requirement built into Aquarius reflects a broader regulatory direction. MiCA requires crypto-asset white papers to include information on the principal adverse impacts of the consensus mechanism used. For proof-of-work assets in particular, this is a disclosure that accounting and sustainability teams need to support with verifiable data, not estimates.

For CFOs at Crypto-Native or Crypto-Holding Businesses

CFOs whose businesses are either applying for MiCA authorisation or advising companies that are should treat legal-tech platforms like Aquarius as one input into a broader compliance infrastructure project. The authorisation process generates obligations that persist after the licence is granted: periodic reporting to national competent authorities, own funds requirements that must be monitored continuously, and custody standards that need to be reflected in treasury and counterparty risk policies.

CFOs should also be assessing their crypto bookkeeping software and broader financial systems against MiCA's record-keeping requirements under Article 75, which require CASPs to maintain detailed records of all services, activities, and transactions in a form that allows supervisors to verify compliance. That is a data architecture question, not just a legal one, and it needs to be addressed in the finance function as well as the compliance team.

Reed Smith's Positioning and the Broader Market Signal

Reed Smith is a firm with established credentials in digital asset transactions: it served as legal counsel to placement agents in Trump Media's Bitcoin treasury financing and advised Nakamoto Holdings in its merger with KindlyMD to create a Bitcoin treasury vehicle. The Aquarius platform extends that transactional expertise into an operational compliance product, which is a direction several large professional services firms are exploring as MiCA creates a sustained demand for authorisation and ongoing compliance support across 27 member states.

The broader signal for the market is that MiCA compliance is becoming a structured, toolable process rather than a bespoke legal exercise repeated from scratch for each client. For accounting firms, that is both an opportunity and a prompt to ensure their own service offerings are integrated with whatever legal and regulatory technology their clients adopt. Firms that can connect legal compliance workflows with financial reporting and audit evidence will be better positioned than those operating in silos.

Frequently Asked Questions

What does Reed Smith's Aquarius platform cover under MiCA?

Aquarius automates crypto-asset classification, regulatory white paper generation, due diligence processes, and ESG disclosures. These are among the most documentation-intensive steps in the MiCA authorisation process. The platform is described as combining automated workflows with Reed Smith's legal expertise, so it functions as a tech-assisted legal service rather than a standalone self-service tool.

Does obtaining a MiCA licence mean ongoing compliance obligations are lighter?

No. ESMA and national competent authorities continue to scrutinise authorised CASPs on cybersecurity, governance, and asset protection standards after the licence is granted. A MiCA authorisation is the entry point; the ongoing compliance burden, including periodic reporting, own funds monitoring, and custody obligations, continues for the life of the licence.

How does MiCA's stablecoin framework affect accounting for non-euro stablecoins?

MiCA imposes volume caps and enhanced requirements on e-money tokens denominated in currencies other than the euro. When an EMT exceeds the transaction thresholds set by the European Banking Authority, restrictions apply to its use as a means of payment in the EU. Accounting teams carrying such stablecoin positions need to monitor both the regulatory status of the token and any changes to MiCA's stablecoin rules, which are currently under discussion in the context of international stablecoin frameworks.

What accounting records must MiCA-authorised CASPs maintain?

MiCA Article 75 requires CASPs to maintain records of all services, activities, and transactions at a level of detail that allows supervisors to verify compliance with the regulation. This has direct implications for the design of a firm's crypto bookkeeping software and data architecture, since the records must be retrievable and auditable on request from a national competent authority.

How should accounting firms position their services alongside legal-tech tools like Aquarius?

Legal-tech platforms handle the classification and regulatory filing layer; they do not replace the financial controls, transaction-level record-keeping, reserve verification, and audit evidence that accounting teams own. Firms that can connect their digital asset accounting software and audit workflows with the compliance outputs from legal-tech platforms will deliver integrated advice rather than fragmented point services. Understanding what a client's compliance platform produces, and what it does not produce, is the starting point.
