NOWPayments is one of the most explicitly adult-friendly crypto gateways on the market, maintaining a dedicated adult-platforms solution page and actively courting cam sites, content stores, and tube operators. It supports 300+ cryptocurrencies including BTC, ETH, LTC, USDT, and XMR, charges around 0.5% per transaction, and operates non-custodially - funds go straight to your wallet. Setup is API-first with WooCommerce and other plugins available.

No KYC is required from end customers, which is a real draw for privacy-sensitive buyers. The flip side: limited fiat settlement, so operators carry crypto volatility risk unless they convert manually.
