Payment gateway and card processing for crypto exchanges with a UK limited company

We arrange gateway and card processing facilities for UK-based crypto exchanges by first understanding your operational and technical requirements. This begins with a review of your checkout flow, target markets, desired payment methods and existing VASP registrations. For a UK Ltd, demonstrating FCA registration as a cryptoasset firm is a foundational requirement.

Based on this profile, we identify the most suitable gateway and acquiring partners. This involves matching your needs to providers that are comfortable with the 6051 MCC (quasi-cash) and have a track record with licensed crypto businesses. We focus on UK and EEA-licensed acquirers and payment institutions that can support card processing for fiat on-ramps in GBP, EUR and USD.

Our process defines the integration scope, confirms the implementation of 3-D Secure to mitigate fraud, and specifies your PCI DSS compliance method. We then assemble a comprehensive submission file for the gateway and its underlying acquirers. This file presents your business in a clear, compliant light, covering everything from your AML policies to your blockchain analytics capabilities. Finally, we coordinate the technical integration and go-live, ensuring a smooth activation of your payment services.

Underwriters for payment gateways and acquirers conduct specific checks on UK-based crypto exchanges. Their primary concern is compliance and risk management. They will immediately verify your firm’s status on the FCA’s cryptoasset register. Operating without this registration is a non-starter.

Next, they scrutinise your AML/CFT policies. This includes reviewing your KYC/KYB procedures for onboarding users, your transaction monitoring systems, and your adherence to the Travel Rule. A contract with a reputable blockchain analytics provider is considered standard. Underwriters assess your fraud controls, paying close attention to the mandatory use of 3-D Secure on all card transactions to combat chargebacks from fraudulent fiat deposits.

They will examine your website, traffic sources and marketing claims to ensure you are not targeting sanctioned jurisdictions or making unrealistic financial promises. The clarity of your transaction descriptors is also reviewed to prevent customer confusion and subsequent disputes. Ultimately, underwriters need to be confident that your UK company is a well-governed, compliant operator, not an unregulated entity attempting to exploit the UK’s corporate framework.

Using a UK limited company provides a credible, regulated foundation for a crypto exchange but comes with specific expectations from payment partners. The UK’s robust regulatory environment means providers expect to see an entity in good standing with Companies House and, crucially, registered with the Financial Conduct Authority (FCA) as a cryptoasset firm. This is not optional.

The UK structure facilitates access to GBP, EUR and USD processing through a strong domestic market of FCA-authorised EMIs and international banks. However, providers will look closely at substance. They expect to see genuine management and control from within the UK, and are wary of UK entities used as a shell by directors based entirely overseas. Your ability to satisfy these 'mind and management' checks is critical.

Reporting requirements for a UK Ltd, including annual accounts and the public Persons with Significant Control (PSC) register, provide transparency that underwriters value. This is a distinct advantage over jurisdictions with less stringent corporate governance. Your file must include your Certificate of Incorporation, PSC register extract, and proof of your UK registered office to confirm the entity’s legitimacy.

Applications from UK crypto exchanges are often declined for reasons related to compliance gaps and perceived risk. The most common reason for rejection is the absence of a valid FCA cryptoasset registration. Many payment providers will not even consider an application without it. We ensure your registration status is clearly evidenced from the outset.

Another major red flag is a weak anti-money laundering framework. If your AML/CFT policy is generic, if you cannot demonstrate effective KYC processes, or if you lack a partnership with a blockchain analytics firm, underwriters will assume high sanctions and illicit finance risk. Our file pre-empts these concerns by detailing your compliance stack and procedures. Similarly, a failure to mandate 3-D Secure across all card transactions is a frequent cause for decline, as it signals a lack of awareness of chargeback risk in the fiat on-ramp process.

Finally, applications can be rejected due to a perceived lack of substance. If the UK Ltd appears to be a 'letterbox' company with no genuine connection to the UK, banks and EMIs will be hesitant to offer accounts. We help you present the evidence of your UK presence and management, demonstrating that your company has legitimate operational ties to its jurisdiction.

For a UK-registered crypto exchange, securing a payment gateway can typically be completed within 1 to 4 weeks, assuming any required acquiring relationships are already in place. The process begins with our preparation of your onboarding file, which collates all corporate, compliance, and technical documentation. Once submitted, the gateway’s compliance team reviews the file, a process that may involve requests for further information or clarification on your business model and controls.

Upon approval, the technical integration phase begins. Your development team will receive API documentation and test credentials to connect your platform to the gateway. We assist in coordinating this process to ensure a smooth and efficient setup. Before going live, a final check is often performed to confirm that the integration is working correctly and that your live website accurately reflects the business model described in the application.

Maintaining a live facility requires ongoing compliance. This means adhering to the gateway's terms of service, keeping your chargeback rates low, and proactively communicating any significant changes to your business, such as entering new markets or altering your ownership structure. Consistent adherence to your stated AML policies and fraud controls is essential for a long-term processing relationship.
