BTCPay Server

BTCPay Server is an open-source, self-hosted payment processor for Bitcoin and a growing list of altcoins (Monero, Litecoin, USDT-Liquid, etc.). It plugs into e-commerce platforms (WHMCS, Shopify, WooCommerce) as a drop-in replacement for proprietary processors like Coinbase Commerce or NowPayments — but with the merchant running their own infrastructure end-to-end, no third-party in the value chain.

For offshore hosts, BTCPay is the gold standard for crypto checkout. The merchant doesn't need a payment-processor relationship (no KYC), funds settle directly to merchant-controlled wallets, and the entire stack is auditable. Major reputable offshore brands (FlokiNET, SilentHosts, Privex) run self-hosted BTCPay. The drawback: requires operating one more service — typically on a dedicated $5-10 / mo VPS.
