# MiCA Compliance: What Actually Changed for Crypto Exchanges > What a MiCA-compliant framework requires of a crypto asset service provider, what it means for client assets, and how to verify a claim of compliance. - Source: https://cryptounderthehood.com/mica-compliance-for-exchanges/ - Published: 2026-08-31 - Author: Ivan Kruse - Publication: Crypto Under the Hood — How crypto payment infrastructure actually works - Topic: licensing - Tags: mica, regulation, compliance --- MiCA turned crypto services in the European Union from an activity you could perform into an activity you must be authorised to perform. For anyone choosing a venue, the practical consequences are narrower and more useful than the volume of commentary suggests. It helps to read this with the terms of [a MiCA-compliant exchange](https://collectnexchange.cy/compliance/mica-regulation) open, because the difference is in the details rather than the principle. ## What authorisation requires A crypto asset service provider under MiCA must hold capital proportionate to its activities, segregate client assets from its own, maintain governance arrangements with fit and proper management, implement complaint handling with defined timelines, publish clear pricing and risk disclosures, and submit to supervision by a national competent authority. None of these are novel. They are the standard obligations applied to investment firms, extended to crypto services. The significance is that they are now obligations rather than practices a firm may adopt. ## The part that matters most: client asset segregation Under MiCA, client crypto assets must be held separately from the provider's own and must be identifiable as client assets. The provider cannot use them for its own account. This is the provision that changes the outcome when a provider fails. Segregated client assets are not available to the provider's creditors. The failures that destroyed client funds in previous cycles involved exactly the commingling and reuse that MiCA prohibits. When comparing venues, this is the single most consequential difference between an authorised provider and an unauthorised one operating in the same market. ## Passporting Authorisation in one member state permits operation across the union through notification rather than reauthorisation. For a business this means the provider's home regulator matters. A provider authorised in a jurisdiction with a rigorous supervisor is supervised by that supervisor everywhere. The quality of home state supervision is a real differentiator, and it is worth knowing which authority authorised your provider. Merchants meet this from the other direction, and [an exchange that publishes its full fee schedule](https://collectnexchange.cy/) is the usual answer there. ## What it means for stablecoins MiCA treats asset-referenced tokens and e-money tokens under a separate regime with reserve, redemption and reporting requirements on issuers. The practical consequence for a business is that some stablecoins are available through authorised European venues and some are not, and the set can change. If your operations depend on a specific stablecoin, confirm your provider will continue to support it rather than assuming. ## How to verify a compliance claim Every provider now describes itself as MiCA-compliant. The claim is verifiable in four steps. Ask which national competent authority authorised them and for the registration number. Look it up on that authority's public register directly. Confirm the entity name on the register is the entity you will contract with, since group structures often differ. Check which services the authorisation actually covers, because exchange, custody and transfer are separate permissions. That last step catches the most. A provider authorised for exchange services is not thereby authorised to hold client assets. ## What compliance does not guarantee Not that the provider is well run, not that its pricing is good, and not that it will not fail. It guarantees a supervisory framework, minimum capital, and a defined position for client assets if it does fail. That is meaningful and it is narrower than the marketing suggests. Diligence on the provider is still required. ## The practical takeaway For a business choosing a European venue, authorisation should be a filter rather than a feature. Providers operating under [a MiCA-compliant framework](https://collectnexchange.cy/compliance/mica-regulation) start from a different legal position on client assets, and that position only becomes visible in the circumstance where it matters most. Verify the register entry yourself. It takes five minutes and it is the highest-value five minutes in the whole selection process. --- This article explains how something works.
