About Simplex

Simplex was founded in 2014 to bridge the gap between traditional fiat payment methods and cryptocurrency. Since then, it has grown to become one of the most widely used payment gateways on the global crypto markets, providing secure payment processing services to hundreds of online merchants.

Having been acquired by Canada-based global payment technology provider Nuvei in 2021, Simplex today works with more than 350 partners, allowing users to purchase over 170 cryptocurrencies with 100+ supported fiat currencies.

Traders who purchase their crypto assets from Simplex brokers can rest assured their transactions are protected by the latest security protocols, and the platform is EU-licensed and compliant with all applicable laws.

How Simplex Works

Since it works as a payment processor rather than a dedicated payment method, there is no need for individual traders to sign up for a Simplex account. Rather, traders will be able to purchase cryptocurrencies directly from Simplex brokers, wallets and exchanges using a range of payment methods, including Visa, Mastercard, Apple Pay, SWIFT and SEPA.

Bear in mind that not all Simplex brokers will accept all of these payment methods. For example, two of the major UK brokers which have integrated this payment processor – OKX and Bitfinex – only support Apple Pay, Visa and Mastercard for Simplex transactions.

In most cases, traders will only have to login to brokers that accept Simplex deposits and provide the relevant information for their chosen payment method on the checkout screen. Once confirmed, the payment is securely processed using advanced anti-fraud algorithms, and the investor should be provided with the digital currency they purchased within hours, if not minutes.

Some Simplex brokers, including OKX, also use this payment processor to allow traders to sell cryptocurrencies for fiat currencies. The exact way this works will depend on the brokerage or exchange, but in OKX’s case, customers can sell BTC for euros and withdraw these to a SEPA bank account.

Retail traders with a valid crypto wallet address can also buy and sell cryptocurrencies directly through Simplex’s website, which links to the ChainBits site for this purpose. They may also wish to open a bank account with the brand, which provides a crypto-friendly Visa card that can be used with brokers that accept Simplex deposits and many other online merchants.

Transfer Times

Crypto exchanges and brokers that accept Simplex payments, such as Binance, are known for their speedy transaction times, with most purchases completed within the same day, and some in just a few minutes. The company’s official website quotes an average transaction time of between 5 and 15 minutes and advises users to contact customer support if the transaction is not complete after 3 hours.

However, some wallets, exchanges or brokers that accept Simplex deposits and payments may require additional time to confirm and process transactions through the payment gateway. For example, the crypto wallet Freewallet states that most transactions through the Simplex gateway will be complete within 24 hours, but the processing time may take up to 48 hours if there is heavy traffic on the network or an issue with the customer’s ID verification.

Fees & Charges

Virtually every transaction on the payment platform carries a processing fee. Additionally, UK traders may incur other processing fees from brokers that accept Simplex deposits and payments.

The standard processing fee of 3.5% to 5% of the total transaction amount is competitive, but still on the pricier end of the crypto payment processing market. Our experts tested a range of transactions of between £50 and £50,000 through the OKX exchange and found that Simplex transactions were always more expensive than competitors including Mercuryo, MoonPay and Coinify.

Traders should also note the $10 (£8.40) minimum processing fee charged by Simplex, as this will push the fee charged on transactions of less than £165 considerably higher than 5%. Additionally, investors may incur other fees from the partners they are using to sell the digital currency.

Finally, note that the availability of transactions directly through Simplex’s homepage is convenient, but may also be prohibitively expensive. The firm lists a processing fee of between 13% and 17% when issuing a purchase from


The firm uses a variety of technologies including end-to-end encryption and two-factor authentication to ensure that customer data remains secure. It also uses advanced fraud-detection algorithms to identify and prevent fraud. Furthermore, all customer data is stored on secure cloud servers and is only accessed by authorized personnel.

The company also offers a zero-chargeback guarantee, which protects online merchants from fraudulent chargeback claims – but may work against traders who have opened a legitimate claim against Simplex brokers.

Customer Support

Simplex provides customers with a comprehensive customer support system. Traders can access the support team through the customer portal, email, or phone.

The support team is available 24/7, and investors can also take advantage of the website’s live chat feature, access the online help centre or submit a ticket to the team about any questions or concerns they have about their transactions.

The top brokers that accept Simplex deposits, also operate 24/5 or 24/7 support through live chat, email or social media. Trading platforms should be able to advise on the status of a deposit or any withdrawal issues.
