OKX review: availability, registrations, custody, and fees
OKX is a large global crypto exchange available in many countries. It holds a MiCA licence in Malta for the European Economic Area and runs a separate United States business that excludes a few states, following a 2025 United States settlement. Availability and the product set vary by country.

OKX is a large, custodial global crypto exchange founded in 2017, offering spot and derivatives trading and a separate self custody wallet. As of April 2026 it holds a MiCA licence from the Malta Financial Services Authority covering the European Economic Area, and it operates a United States platform in most states after a February 2025 settlement in which an affiliate pleaded guilty to operating an unlicensed money transmitting business. New York, Texas, and a few territories are excluded. Whether you can use it legally depends on your own country, so check that first.
What OKX is
OKX was founded in 2017 and is one of the larger crypto exchanges by trading volume. It offers spot trading, derivatives in markets where it is authorised, staking and earn products where permitted, and a separate self custody wallet that lets users hold their own keys and access decentralised applications. The centralised exchange is custodial, meaning OKX holds the assets in your account on your behalf.
OKX has been the subject of significant United States enforcement. In February 2025 an OKX affiliate, Aux Cayes Fintech, pleaded guilty to operating an unlicensed money transmitting business and agreed to penalties of more than 500 million dollars (as of April 2026). The company has since emphasised licensing and compliance, including its European MiCA authorisation and a United States entity, which is relevant context for anyone assessing where OKX can legally operate.
Where OKX is available
As of April 2026 OKX is available in many countries across Asia, Europe, Latin America, and beyond. Across the European Economic Area it serves clients through OKX Europe, which holds a MiCA licence from the Malta Financial Services Authority secured in January 2025, giving it a settled European position ahead of the 1 July 2026 transitional deadline. It has also obtained a European payments licence to support card and stablecoin features.
In the United States, OKX operates a separate United States entity that serves customers in most states. As of April 2026 it does not provide services to residents of New York, Texas, American Samoa, Guam, the Northern Mariana Islands, or the United States Virgin Islands. A federal FinCEN registration does not by itself authorise operation in every state, so the available product set and supported states can change. Confirm what is offered in your location before you sign up.
Registrations and licences
- European Economic Area. A Markets in Crypto Assets (MiCA) licence held by OKX Europe, authorised by the Malta Financial Services Authority, used to serve clients across European Economic Area member states (as of April 2026).
- United States. A separate United States entity registered with FinCEN as a Money Services Business, operating with state money transmitter licences and excluding New York, Texas, and a few territories, after the February 2025 settlement (as of April 2026).
- Other markets. OKX holds further registrations and approvals in additional jurisdictions and publishes its licences on its own site, which is the most current reference (as of April 2026).
Each registration is stated as of 21 June 2026. Licences and registrations change. Confirm the current position on the regulator register and the licences page of the platform before acting.
Custody, fees, strengths, and limitations
On the centralised exchange OKX is custodial, holding your assets in its own wallets. It also publishes a separate self custody OKX Wallet that lets users hold their own private keys and interact with decentralised applications, so the two products differ in who controls the keys. OKX publishes proof of reserves information, which is one input rather than an audited guarantee.
On fees, OKX uses a tiered maker and taker model across spot and derivatives that is generally competitive for active traders, with discounts at higher volume tiers. Exact pricing changes over time and varies by product and region, so confirm the current schedule on the platform before trading.
In plain terms, the strengths are broad availability, deep liquidity, a settled European licence, a self custody wallet option, and competitive trader fees. The limitations are the regulatory overhang from the 2025 settlement, the excluded United States states, and the custodial default on the exchange. None of this is a recommendation to use or avoid the platform, only the factual picture to weigh against your own country and needs.
OKX is one of several platforms, and whether it is available depends on where you live. Rather than assume, compare the exchanges that are genuinely available in your country before you choose.
Regulator and sources
The relevant regulators differ by market: the Malta Financial Services Authority for the MiCA licence used across the European Economic Area, and FinCEN with state regulators in the United States. The February 2025 settlement was handled by the United States Department of Justice for the Southern District of New York.

Frequently asked questions
Is OKX legal to use?

Legality of using it still depends on your own country, so check your local rules.
Can United States residents use OKX?
In most states, through the OKX United States entity. As of April 2026 OKX operates a United States platform but does not serve residents of New York, Texas, and a few territories. This follows a February 2025 settlement in which an OKX affiliate pleaded guilty to operating an unlicensed money transmitting business and paid penalties of more than 500 million dollars. Check availability for your state.
