Safeguarding client crypto assets under MiCA: segregation and custody rules
Safeguarding client crypto assets is now a core licensing obligation for any CASP serving EU clients, and MiCA sets out specific segregation and custody rules that go well beyond holding coins in a single wallet. This post breaks down what those rules require in practice and how they interact with offshore structures such as a Panama Sociedad Anonima.
What MiCA Changed for Crypto Custody
MiCA has been in force across the EU since 2024, with the full CASP regime applying from December 2024 and national supervisors actively authorising and supervising firms through 2026. For any business providing custody and administration of crypto assets on behalf of clients, the regulation turns custody from an operational detail into a licensed activity with capital, governance and conduct requirements attached. A firm cannot simply hold client keys and call itself a custodian; it must be authorised as a CASP and meet the specific custody obligations in the regulation.
The core principle is that client crypto assets are not the firm's assets. MiCA requires CASPs to make arrangements to safeguard clients' ownership rights, to keep client assets separate from the firm's own assets, and to ensure that client assets are not treated as belonging to the CASP in insolvency. This is a structural requirement, not just a bookkeeping one, and it shapes how wallets, keys, accounts and legal entities are organised.
For founders used to operating in lighter-touch jurisdictions, the shift is significant. MiCA does not just ask whether you can keep coins safe from hackers; it asks whether a court, an administrator or a supervisor could clearly identify which assets belong to which clients and return them if the firm fails. That legal clarity is the point of the segregation rules.
Segregation of Client Crypto Assets: The Core Rules
Segregation under MiCA means client crypto assets must be held separately from the CASP's own assets. In practice, this typically means separate wallets or separate accounts, clearly labelled, with no commingling of firm and client funds. Where a CASP holds multiple clients' assets, it must maintain records that allow each client's entitlement to be identified at any time. The regulation also requires that client assets be held in a way that protects them from the claims of the CASP's creditors.
A common question is whether omnibus structures are allowed. MiCA does not require one wallet per client, but it does require that the CASP can identify each client's assets and that the arrangement does not undermine client ownership. Omnibus holding is possible where records and controls are strong enough to allocate assets accurately, including in an insolvency scenario. Many firms use a mix: omnibus for hot wallet operations with strict internal ledger controls, and segregated cold storage for the bulk of client assets.
Segregation also has a governance dimension. MiCA expects policies and procedures covering how client assets are received, held, transferred and reconciled. Reconciliation should be frequent enough to catch discrepancies quickly, and any shortfall should trigger escalation and remediation. Supervisors will look for evidence that segregation is not just a policy document but an operating reality, tested and reviewed.
Custody Arrangements, Key Management and Third Parties
MiCA requires CASPs providing custody to have strong arrangements for safekeeping, including key management. The regulation does not prescribe a single technical standard, but it does expect controls that match the risk. That usually means a documented key management policy, separation of duties, multi-signature or threshold schemes for material wallets, and secure backup and recovery procedures. Private keys and seed phrases should not sit with a single individual without oversight.
Where a CASP uses a third party, such as a sub-custodian, exchange or wallet provider, MiCA imposes conditions. The CASP remains responsible for meeting its obligations, so due diligence, contractual protections and ongoing monitoring are necessary. The third party should be subject to equivalent standards where relevant, and the arrangement should not weaken client ownership or segregation. Outsourcing custody does not outsource regulatory responsibility.
Liability is another key point. MiCA makes CASPs liable to clients for the loss of crypto assets or keys caused by the CASP's own fault. That makes insurance, capital buffers and strong operational controls commercially important, not just compliance checkboxes. Founders should assume that a custody failure will be assessed against the firm's policies, records and actual behaviour, so documentation and testing matter.
Capital Requirements and the Custody Activity Class
MiCA sets minimum own funds requirements for CASPs based on the activities they provide. For custody and administration of crypto assets on behalf of clients, the relevant tier is generally the middle or higher class depending on the combination of services. The commonly cited tiers are EUR 50,000, EUR 125,000 and EUR 150,000, with the highest tier applying to firms providing custody alongside trading or other more complex services. The exact figure depends on the services authorised, so founders should confirm the applicable class with their supervisor or adviser.
Capital is not a substitute for segregation, but the two work together. A firm with thin capital and weak segregation is a supervisory concern; a firm with adequate capital and clear segregation is easier to supervise and more credible to institutional clients. MiCA also expects governance and risk management proportionate to the custody activity, including independent oversight where the firm is large enough.
For planning purposes, founders should treat the capital requirement as a floor, not a target. Operating a custody business in the EU involves legal, compliance, security and audit costs that often exceed the minimum capital. The licensing process itself requires a credible business plan showing how the firm will meet ongoing obligations, not just the application fee.
Panama Structures and EU Custody: How They Fit Together
Panama does not have a dedicated crypto licence. Founders looking for an offshore base typically incorporate a Sociedad Anonima, which can be set up in around two to three weeks in many cases. Panama's territorial tax system generally means foreign-source income is not taxed locally, and the corporate framework is familiar to international advisers. That makes Panama attractive as a holding or operating company for activities outside regulated EU custody.
However, a Panama company does not exempt a firm from MiCA if it provides custody to EU clients or operates in the EU. MiCA applies based on the location of the client and the nature of the activity, and reverse solicitation has narrow limits. A Panama entity can be part of a group structure, but the EU-facing custody activity will generally need an authorised CASP, with segregation, capital and governance meeting MiCA standards. Using an offshore entity to hold client assets while an EU entity fronts the service creates legal and supervisory risk if the arrangement is not carefully structured.
The practical approach for many founders is a two-part structure: a Panama or similar offshore entity for non-EU business and treasury, and a separate EU CASP for EU clients, with clear contractual and operational separation. Client assets for EU custody sit within the regulated perimeter, while the offshore entity does not commingle or control those assets. This is not a loophole; it is a way to keep regulated and unregulated activities distinct so that segregation and insolvency treatment remain clear.
Practical Steps to Meet MiCA Custody Expectations
Start with a mapping exercise. Identify every client asset flow, every wallet and account, and every third party involved in holding or moving assets. Then document how each client's entitlement is recorded and how it would be proven in an insolvency or supervisory review. Gaps in this mapping are usually where enforcement risk begins.
Next, build the control environment. That means written policies for segregation, key management, reconciliation, incident response and outsourcing, plus evidence that they operate. Multi-signature or threshold schemes, access controls, and independent review of wallet operations are common expectations. Reconciliation should be regular and documented, with clear escalation for breaks.
Finally, align the legal structure with the regulatory one. If you are using a Panama SA or similar offshore vehicle, make sure the EU custody activity is properly licensed and that client assets are not held in a way that blurs the line between entities.

How to Choose the Right Jurisdiction
Work the decision in this order: customers first, everything else second:
- Who are your customers? EU retail means you need a MiCA passport (Lithuania, Malta or another EU CASP). US customers mean state-by-state money-transmitter licensing or a FinCEN MSB, so consider a Canada MSB or a US setup. Latin America, Asia or HNW clients mean an offshore or territorial base such as Panama is usually the better fit.
- Do you need a regulator badge? A public-facing exchange chasing institutional partners and fundraising often needs the reputational lift of an EU, Swiss or VARA licence. An OTC desk or token treasury usually does not.
- What is your budget and timeline? Offshore and territorial routes set up in weeks for tens of thousands; premium onshore licences take many months and six figures.
- What about tax? Territorial-tax jurisdictions like Panama charge 0% on foreign-source income; EU jurisdictions apply standard corporate tax. Factor total cost of ownership, not just setup fees.
For many offshore-first founders, Panama lands at the intersection of fast incorporation, low cost and 0% tax on foreign-source income, which is why it features so heavily in our work. But the honest answer is that the “best” jurisdiction is the one that matches the four answers above, and that is a conversation worth having before you spend a cent. See our cost breakdown and application process to ground the decision in real numbers.
Banking and Compliance: Where Most Setups Actually Stall
Incorporation is the easy part of any crypto project. Banking is where timelines slip and where under-prepared founders lose months. Since 2023, banks and payment processors worldwide have tightened their onboarding of crypto-adjacent businesses, and they now expect a genuinely professional application , not a one-page business summary. A thin file is simply rejected, and re-applying with the same bank is far harder than getting it right the first time.
Three documents do the heavy lifting. The first is a written AML/KYC compliance program: your customer-onboarding flow, transaction-monitoring rules, sanctions and PEP screening, a named compliance officer, and record-keeping policies. The second is a clear, evidenced source-of-funds file for both the company and its beneficial owners. The third is a coherent business description that explains who your customers are, how money moves, and what volumes you project. Banks approve businesses they understand; ambiguity reads as risk.
Sequencing matters as much as substance. The correct order is: incorporate the operating entity, build the compliance program, assemble the source-of-funds package, and only then approach banking, ideally through a warm introduction rather than a cold application. Founders who approach banks mid-setup, before their file is complete, create the very delays they are trying to avoid. We make direct introductions to banks and crypto-friendly payment rails as part of every engagement, but the introduction only works if the file behind it is ready.
None of this is optional, and none of it changes much from one jurisdiction to the next, the compliance bar is now broadly global. What changes is the appetite of local banks and the speed of onboarding. Our requirements checklist sets out exactly what you need to assemble before you approach a bank.
Crypto Licensing in 2026: The Bigger Picture
Choosing where to license a crypto business in 2026 is no longer a simple cost calculation. The regulatory map has hardened considerably over the last three years. In the European Union, the Markets in Crypto-Assets Regulation (MiCA) has replaced the patchwork of national VASP registers with a single Crypto-Asset Service Provider (CASP) authorisation that passports across all 27 member states. That passport is powerful, but it comes with capital requirements, governance obligations and a multi-month authorisation process that smaller projects often underestimate.
Outside the EU, the picture is more varied. Offshore and territorial-tax jurisdictions compete on speed, cost and privacy, while major financial centres such as Switzerland, the UAE and Singapore compete on credibility and institutional access. The Financial Action Task Force (FATF) sits over all of them: its “travel rule” and AML standards now apply, in some form, almost everywhere a serious crypto business would consider basing itself. Jurisdictions that ignore FATF expectations end up grey-listed, which quietly closes correspondent-banking doors for every company registered there.
This is why the question behind Safeguarding client crypto assets is rarely “which licence is cheapest?” It is “which regime matches my customers, my risk appetite and my banking needs?” An EU-retail exchange and an offshore OTC desk serving high-net-worth clients in Latin America have almost nothing in common in terms of the right base. Getting this decision right at the start saves you from the single most expensive mistake in the industry: licensing in the wrong place and having to re-domicile a live business.
Consulting24 has guided more than 200 crypto company setups across 15+ jurisdictions since 2017, which means we have seen how each of these regimes behaves in practice rather than just on paper. The summary below is the same framework we use with clients, and we are always happy to map it to your specific model. Start with our Panama vs Lithuania comparison to see how the trade-offs play out between an offshore base and an EU-passported one.
Common Mistakes to Avoid
The failures we see when founders research Safeguarding client crypto assets on their own are remarkably consistent, and almost all of them are avoidable. The first is licensing to the headline tax rate. A 0% jurisdiction is worthless if your customers legally require a regulated provider you cannot become there, and you will simply have to start again. Decide who you are allowed to serve first, then optimise for tax.
The second is treating the compliance program as paperwork. The AML/KYC program is not a formality to satisfy a regulator; it is the document your bank reads most closely. A generic template downloaded from the internet is transparent to any compliance officer and will sink your banking application. It needs to reflect your actual product, customer base and risk profile.
The third is underestimating banking lead time. Founders routinely budget for incorporation and forget that the bank account, the thing that actually lets the business operate, can take longer than the licence itself. Build banking into your launch timeline from day one, not as an afterthought.
The fourth is ignoring personal tax residency. A company in a low-tax jurisdiction does not erase your obligations where you personally live. Many founders create unexpected liabilities by structuring the company perfectly and ignoring themselves. We introduce qualified tax advisors precisely to close this gap.
The fifth and most expensive is choosing a provider on price alone. The cheapest setup that results in a rejected bank application or a re-domiciliation is far more expensive than doing it properly once. Ask any provider to itemise their fee and explain their banking track record before you commit.
What Happens After You Are Licensed
Getting licensed and banked is the start, not the finish. Every regulated or registered crypto business carries ongoing obligations, and letting them lapse is how companies lose their standing, and their banking. At minimum you will maintain a registered agent or local presence, file annual renewals or supervision fees, keep accounting records, and keep your compliance program live with periodic reviews and updated sanctions and PEP screening lists.
Most jurisdictions also expect you to keep your beneficial-ownership information current and to report material changes, new directors, new shareholders, a pivot in business activity, promptly. Transaction monitoring is not a one-time setup either; screening rules need tuning as your volumes and customer mix evolve. Banks may request periodic refreshes of your KYC and source-of-funds documentation, particularly after a year of trading or a significant change in activity.
This is why we offer ongoing maintenance on an annual retainer rather than treating setup as a one-off transaction. The cost of staying compliant is a fraction of the cost of losing a banking relationship and having to rebuild one from scratch. Plan for it in your year-two budget from the outset, and treat your compliance function as a living part of the business rather than a box you ticked at launch.
It is also worth planning ahead for growth. A structure that suits a pre-revenue startup may not suit the same company once it is processing meaningful volume, adding new product lines, or expanding into new markets. Many of the businesses we work with begin in a fast, low-cost offshore base to validate the model, then add a second regulated entity, an EU CASP, for example, once revenue justifies the cost and the market access genuinely matters. Designing the first structure with that possible second step in mind keeps your options open and avoids a disruptive re-domiciliation later. We map this growth path out with clients during the initial planning stage so the early decisions support, rather than constrain, where the business is heading.

Frequently Asked Questions
What does segregation of client crypto assets mean under MiCA?
It means client crypto assets must be kept separate from the CASP's own assets, with records that identify each client's entitlement, so that client assets are protected from the firm's creditors and can be returned if the firm fails. It is a legal and operational requirement, not just a technical one.
Can a CASP hold all client assets in one omnibus wallet?
MiCA does not ban omnibus holding, but the CASP must be able to identify each client's assets and ensure client ownership is protected, including in insolvency. Strong internal ledgers, controls and reconciliation are essential, and many firms use a mix of omnibus hot wallets and segregated cold storage.
What are the MiCA capital tiers for CASPs?
The commonly cited minimum own funds tiers are EUR 50,000, EUR 125,000 and EUR 150,000, depending on the activities provided. Custody and administration of crypto assets on behalf of clients generally falls into the middle or higher class, and the exact figure depends on the combination of services authorised.
Does a Panama company need a MiCA licence to custody crypto for EU clients?
If the firm is providing custody to EU clients or operating in the EU, MiCA can apply regardless of where the company is incorporated. A Panama Sociedad Anonima does not exempt the activity from MiCA. Many groups use an offshore entity for non-EU business and a separate authorised EU CASP for EU custody.
Is there a crypto licence in Panama?
Panama does not have a dedicated crypto licence. Founders typically incorporate a Sociedad Anonima, which can often be set up in around two to three weeks, and Panama's territorial tax system generally means foreign-source income is not taxed locally. That structure does not replace EU licensing where MiCA applies.
What happens if a CASP fails and client assets are not properly segregated?
Poor segregation can lead to client assets being treated as part of the firm's estate, delays or losses in recovery, and supervisory enforcement. MiCA requires arrangements that protect client ownership and keep client assets separate, so failures in this area are a serious regulatory and commercial risk.
Can a CASP outsource custody to a third party?
Yes, but the CASP remains responsible for meeting MiCA obligations. That means due diligence, contractual protections, ongoing monitoring and ensuring the arrangement does not weaken client ownership or segregation. Outsourcing does not transfer regulatory responsibility.
How should founders prepare for MiCA custody requirements?
Map all client asset flows, wallets and third parties, document how each client's entitlement is recorded and proven, and build written policies for segregation, key management, reconciliation and outsourcing with evidence they operate. Align the legal structure so EU custody sits within a properly authorised CASP. Advisers such as Consulting24 can assist with licensing and structuring.
