What Is Simplex?
Simplex is a decentralised finance (DeFi) payment gateway providing digital solutions to a large number of crypto exchanges. It is a third-party service provider that facilitates credit card purchases of crypto assets.
Two major fiat currencies currently supported are GBP and EUR, making it easy to use in the UK and Europe. The system is also available for traders outside the European continent.
Simplex was founded in 2014 by Nimrod Lehavi, the creator, CEO and previous member of the Israeli Bitcoin Association, alongside two ex-PayPal employees, Erez Shapira and Netanel Kabala. Equipped with an impressive background and history in online transaction technology, the trio created the company to offer online payment processing with added fraud protection.
Simplex legitimises the use of cryptocurrency and its third-party nature helps keep your information safe from hackers, which has helped grow its popularity within the trading community. Moreover, it uses a proprietary Python AI algorithm that further aids in mitigating potential fraud.
You can pay with your credit or debit card in a faster and more secure manner than some other alternatives, like Moonpay.
Fees
Some charges are applicable when using the Simplex online network, with fees up to 5% of the transaction value. On top of this, there is a minimum fee of USD 10. Some external wallets or websites may charge additional fees per transaction and conversion charges may apply for payments not in USD.
Speed
Simplex deposits are fast, often instantaneous, though withdrawals generally take 5-15 minutes. That being said, withdrawals can take up to three hours, depending on the market demand.
If your crypto has not been returned after this, reach out to the customer service team using the live chat function in the lower right corner of the website. This can also be used for any other questions you may have.
Security
Simplex claims strong levels of payment security, with de-frauding systems in place and a zero chargeback guarantee. However, detailed information regarding these systems is not provided on the website, though customer reviews do seem positive regarding this matter.
