How to accept cryptocurrency payments: A guide for merchants

Cryptocurrency is no longer a niche payment experiment. Consumer adoption of digital currencies in the UK and across the EEA has grown consistently, and a segment of your potential customers already prefers to pay with Bitcoin, Ethereum, or stablecoins over conventional payment methods.

For established merchants, the question is no longer whether cryptocurrency payments are viable. The relevant question is whether accepting them creates a meaningful commercial opportunity, and what it takes to do it responsibly.

This guide covers the benefits of accepting cryptocurrency payments, how to get set up with crypto payment processing, and the risks and regulatory considerations to work through before going live.

What are cryptocurrency payments?

Cryptocurrency payments are digital transactions in which a buyer transfers value to a merchant using a decentralised digital currency—such as Bitcoin, Ethereum, or a stablecoin—recorded on a blockchain rather than processed through a traditional banking intermediary.

From a merchant's operational perspective, the key difference from card payments is the settlement path. The transaction bypasses the acquiring bank, card network, and payment processor, going directly from the customer's wallet to the merchant's, validated by the blockchain network and typically settled within minutes.

The most commonly accepted cryptocurrencies in merchant contexts are Bitcoin (BTC), Ethereum (ETH), and stablecoins such as USDC or USDT. Stablecoins—pegged to a fiat currency—are increasingly preferred by merchants who want to accept crypto without exposure to price volatility.

Why merchants are accepting crypto payments

Crypto payment adoption is growing among merchants, though the picture varies considerably by geography and business size. A January 2026 Harris Poll survey commissioned by the National Cryptocurrency Association (NCA) found that 39% of U.S. merchants now accept digital assets at checkout, with overwhelming consensus that crypto payments will become a standard option within the next five years.

Nearly nine in ten merchants (88%) report receiving inquiries from customers about paying with cryptocurrency, and more than two-thirds (69%) say customers request these payments at least once a month.

Global adoption figures paint a more cautious picture. The Visa and Merchant Risk Council's 2025 Global eCommerce Payments and Fraud Report, drawn from over 1,000 merchants across 38 countries, found that only approximately 10% of merchants accept cryptocurrency at checkout, making it the least accepted payment method in the survey.

The divergence likely reflects the difference between a U.S.-focused advocacy survey and a broader international merchant base that includes European markets, where crypto adoption has historically trailed North America.

For merchants evaluating the decision, the commercial case is practical rather than ideological:

• Faster settlement. Crypto transactions settle directly on the blockchain, typically within minutes, without waiting on bank clearing cycles. Faster transaction speed is the top benefit cited by merchants already accepting crypto, named by 45% of respondents.
• Reduced chargeback exposure. Blockchain transactions are irreversible by design. Once confirmed on-chain, a payment cannot be reversed through a card network dispute process, which reduces exposure to traditional chargebacks.
• Lower cross-border friction. Accepting crypto payments removes the FX conversion fees and international transaction surcharges associated with cross-border card payments, making it particularly relevant for merchants serving customers across the EEA.
• Access to crypto-native customers. 79% of merchants agree that accepting crypto could help them attract new customers. Among merchants already accepting it, cryptocurrency accounts for over a quarter (26%) of total sales, with roughly 72% reporting growth in crypto transactions over the past year.

How to accept crypto payments

Adding cryptocurrency as a payment option does not require rebuilding your checkout. Most established merchants implement it through a dedicated crypto payment processor that handles the technical and compliance layer on their behalf. The process broadly follows five steps.

1. Choose a crypto payment processor. In the UK, verify that the processor holds FCA registration under the Money Laundering Regulations; under the new FSMA (Cryptoassets) Regulations 2026, full FCA authorisation is required from October 2027. In the EEA, MiCA requires processors to hold a CASP licence, which provides passporting across all EU member states—the transition deadline for most member states was July 2026.
2. Integrate with your checkout. Most processors offer API integration or pre-built plugins for common e-commerce platforms. Your developer or payment consultant can advise on the most appropriate integration method for your stack.
3. Configure your accepted currencies. Start with the highest-demand options—typically BTC, ETH, and one or two stablecoins—rather than enabling every available currency at once. A narrower list is easier to manage and reduces settlement complexity.
4. Set your settlement preference. Decide whether you want to receive payment in the original cryptocurrency or have the processor convert it to fiat (GBP or EUR) at the point of settlement. Fiat settlement eliminates volatility exposure but may carry a conversion fee.
5. Test the flow before going live. Run end-to-end test transactions across each accepted currency to verify that confirmations, receipts, and your accounting records are all functioning correctly.

Merchants operating in the UK and EEA are not themselves required to register as crypto asset service providers when accepting payments through a licensed processor.

However, they must onboard with a processor that holds the relevant regulatory permissions—FCA registration (and FSMA authorisation from October 2027) in the UK; a MiCA CASP licence in the EEA—and ensure that the processor's AML, KYC, and transaction monitoring obligations are being met on their behalf."

Risks and considerations

The commercial case for accepting crypto payments is genuine, but implementing without prior risk assessment is premature. Four areas warrant attention.

Regulatory compliance

In the UK, the FSMA 2000 (Cryptoassets) Regulations 2026 were passed by Parliament in February 2026, establishing full FCA authorisation requirements for cryptoasset service providers from October 2027. In the EEA, the EU's MiCA regulation is now fully in force, with transitional permissions expiring July 2026.

For most merchants accepting payments through a licensed processor and converting immediately to fiat, the compliance obligations sit with the processor rather than the merchant. However, you should confirm this with your legal adviser based on your specific setup.

Limited consumer adoption in some sectors

Crypto payment adoption varies significantly by sector and customer demographic. For most UK and EEA consumer segments, card payments and open banking remain the dominant preference. Crypto is most likely to drive incremental conversion in digital goods, online trading, and cross-border e-commerce.

Tax treatment

HMRC treats cryptocurrency as a capital asset rather than currency. For businesses, receiving crypto as payment is first treated as trading income at the sterling value on the date of receipt. Any subsequent conversion to fiat is then a separate chargeable event—potentially subject to Corporation Tax on chargeable gains.

For sole traders, Capital Gains Tax applies to any gain on disposal. CARF reporting requirements have also applied from 1 January 2026, requiring crypto service providers to report transaction data to HMRC.

Getting crypto payments right

Cryptocurrency payments are a viable addition to an established merchant's checkout, provided the setup is deliberate. The benefits are real — faster settlement, reduced chargeback exposure, and access to a crypto-native customer segment—but they come with trade-offs around volatility, regulatory compliance, and tax treatment that require active management.

Getting the setup right means choosing a processor that operates within a compliant framework, configuring your settlement preferences to match your risk appetite, and ensuring your accounting processes can handle crypto receipts from day one.
