Fiat-to-crypto gateway backed by Nuvei with 200+ supported cryptocurrencies
Simplex is a fiat-to-crypto payment gateway used through exchanges, wallets and other Web3 platforms. The Nuvei-owned service supports more than 200 cryptocurrencies, over 100 fiat currencies and 350+ partner integrations across 245+ global markets. It also offers an off-ramp for selling Bitcoin and USDT on TRC20 to Visa cards in EUR within the European Economic Area.
Simplex was founded in Israel in 2014 by Nimrod Lehavi, Erez Shapira and Netanel Kabala. Lehavi was the company’s co-founder and CEO. Nuvei acquired Simplex for approximately US$250 million in 2021. Simplex’s EU entity holds an Electronic Money Institution license from the Bank of Lithuania, and the company is a principal member of Visa.
Simplex is normally embedded inside a partner platform rather than used as a standalone exchange. Customers select an asset and payment method in the partner’s interface, complete the required payment and identity checks, then receive the crypto through that platform. Supported methods include Visa and Mastercard credit or debit cards, Apple Pay, Google Pay, SEPA, ACH, PIX and other alternatives. The company also provides a customisable widget and APIs for businesses.
Asset and payment availability depends on the customer’s location, device and partner. Simplex states that its payment infrastructure supports 570+ alternative payment methods. In the United States, Visa debit is the supported card type identified in the service information.
Card purchases generally carry a 3.5% to 5% processing fee, with a minimum fee of US$10. The transaction can also include a network fee and a spread added by the partner exchange. Bank-transfer and local payment costs vary by method and location.
Simplex states that its services reach 245+ markets and that its gateway is available in 190+ countries, with regional restrictions for particular assets and payment methods. The company launched its off-ramp in 2024 for EEA users selling Bitcoin and USDT on TRC20 to Visa cards in EUR. Its website says millions of customers use the service, and its Trustpilot profile had about 29,000 reviews with a 4.0 out of 5 score in September 2026.
Card purchases can be expensive once the processing fee, network fee and partner spread are combined. Transactions depend on Simplex, the partner platform and banking or card networks, so regional restrictions and payment failures can affect delivery. The service is also an intermediary payment gateway, not a self-custody wallet, and the available asset list changes by partner and location.
Simplex offers broad payment and asset coverage through partner platforms, but card purchases carry a 3.5% to 5% fee with a US$10 minimum.
Simplex is a fiat-to-crypto payment processor founded in Israel in 2014 and acquired by Nuvei in 2021 for approximately US$250 million. It usually appears inside an exchange, wallet or other partner platform rather than as a standalone trading venue. This model gives it broad distribution. Available assets and payment methods depend on the partner and location.
Simplex lists 200+ cryptocurrencies, 100+ fiat currencies, 350+ partner integrations and access across 245+ global markets. Its FAQ describes availability in 190+ countries, while the broader market figure refers to markets, so regional access still depends on the asset, payment method and partner. The service accepts Visa and Mastercard cards, Apple Pay, Google Pay, SEPA and ACH, alongside 570+ alternative payment methods. For US customers, the documented card option is Visa debit only.
Fees are the main drawback for card buyers. The card processing charge is generally 3.5% to 5%, with a minimum of US$10, before any network fee or spread added by the partner exchange. That is a meaningful cost on smaller purchases.
Simplex provides a widget and APIs. It also offers fraud-prevention infrastructure. Developers can connect crypto purchases to wallets and exchanges through the widget and APIs. The trade-offs are regional gaps and possible payment failures. Simplex does not provide a general-purpose exchange or self-custody wallet: its documented card sell service supports Bitcoin and USDT on TRC20 to EUR Visa cards for users in the European Economic Area.
Simplex is owned by Nuvei, holds an Electronic Money Institution license from the Bank of Lithuania and is a principal member of Visa. Simplex also reports millions of customers.
