Open-source payment processor that converts Bitcoin (and other cryptocurrencies) to fiat or holds it as-is, without intermediaries, KYC, or third-party risk. You run it on your own server; payments hit your wallet directly.
Why it matters for domain ops: BTCPay lets you accept crypto for domain registration, renewal, and services without touching Stripe, PayPal, or traditional payment rails. No account freezes. No compliance theater. No chargebacks. Transactions settle to your keys—full stop.
Common setup: self-hosted BTCPay instance + Lightning Network for fast, low-fee settlements. Some registrars (including bulletproof ones) use it as their backend. You can also run it privately to accept domain payments from clients who want zero KYC friction.
Trade-off: you manage server uptime, SSL, backups. But that's the point—sovereignty costs attention. Pairs well with offshore hosting and anonymous registration workflows.
