CoinGate is a Lithuanian payment gateway founded in 2014, now MiCA-licensed and serving a large merchant base across many countries. It accepts adult entertainment merchants under its standard AML and KYC compliance framework, supports 150+ cryptocurrencies, and unusually offers EUR, USD, and GBP fiat settlement - so you can take crypto and get euros in your bank account. Pre-built plugins cover WooCommerce, PrestaShop, and WHMCS.

The KYC requirement extends to business verification, which adds some paperwork upfront. Not the most adult-focused product, but the regulated EU standing and fiat rails make it a credible choice for operators who want a clean payment stack.
