Ask HN: What crypto payments options should I offer for my VPN?

3 willprice89 3 8/3/2025, 3:10:17 AM

I run a VPN service designed to get around censorship. Customers are mainly people in countries like China, Iran, and Russia. Unfortunately those countries don't have easy access to common Western payment methods (credit cards, PayPal etc.)

I thought adding a cryptocurrency payment option could give more people access, but I don't have any real experience in the area and the information I've found searching online seems extremely unreliable.

So I'm hoping I can get some better answers from Hacker News. Here are my questions:

1. Is crypto a good choice for this use case? Are there other options that would achieve my goal (allow people who can't use Western payment methods to pay)?

2. Could I start with one or just a few specific cryptocurrencies? Or do I need to support a whole bunch of different coins?

3. Any recommendations for self-hosted tools or third-party processors for actually accepting the payments?

I was looking into it as well but I have not found any payment gateway that would accept crypto, convert it into fiat and send it to me as payment as a single step process. I found some that could do it in multiple steps, which makes no financial sense, and they also charge for any movements. So to me, it looks like crypto is a no go for any legal business, for now. Maybe if you would be incorporated in El Salvador where crypto is legal tender and you would not have to involve fiat. But for most, that is not an option.

Maybe one day..

Mullvad accepts cash payments where you send the amount due via mail. They also offer a choice of Cryptos. See: https://mullvad.net/en/pricing

1. Yes, this is a problem crypto solves.

2. You can just start with a stable coin like USDC, this way you don't have to do any calculations. Just tell them the dollar amount.

3. Give the person paying your wallet address.
