Setting up your own crypto payment system?

I've been receiving crypto payments on Coinpayments for years, and suddenly they want KYB, asking me for a bunch of info which I don't have. I just have a website and I sell services on it. There are no contracts, invoices, registered business, and all that insanity.

I sent them the info they requested and explained the situation, but they may reject me. And seeing as we're talking about crypto, not a bank, I'm tempted to create my own payment gateway thing for my website. Crypto is the one payment method where I don't have to deal with sending my dick pick while erect with a ruler next to it while standing on my head with my thumb in my mouth.

Did anyone set up their own payment gateway? Is it hard? Any advice?

Setting up your own gateway isn't as bad as it sounds but "your own" is doing a lot of heavy lifting here. If you mean literally watching the blockchain for incoming payments to addresses you generate, thats very doable. You spin up something that derives a fresh address per order from an xpub, poll a node or an API for confirmations, then mark the order paid. BTCPayServer does exactly this and its self hosted, no KYB, no middleman holding your funds. Thats probably what you actually want instead of coding it from scratch.

The catch people forget is the boring stuff... you become your own support desk. Failed payments, wrong amounts sent, underpayments, guy sends after the rate moved and now hes 4 bucks short, chain fees eating small payments, exchange rate locking during the checkout window. Coinpayments ate all that for you. Not hard, just tedious and its on you now.

If you go BTCPay you can run it on a cheap VPS or even use one of the third party host options so you dont have to sync a full node. Monero + BTC + a couple stablecoins covers most people.

Honestly the KYB push isnt going away though, more of these processors are doing it every year, so learning to self host now is the right move regardless of whether coinpayments takes you back.

I've used NowPayments before and they're KYC free as far as I am aware. They rapidly route payments to your own wallet.

I would recommend BTCPay as well, but it's primarily built for BTC network and the Altcoin support is pretty flaky and sometimes too technical.

Also, the issues that @BidNomad pointed out are pretty spot on. Self serving things is more hassle than you'd like and unless you're doing crazy volumes in crypto, so much so that you can allocate resources to managing the payments, it's simply not worth the setup, infra and other efforts.

Also, I am just going to drop this here - please do your due diligence. I haven't used it, just heard of it and can see that it hasn't updated since November 2025.

It's not hard. I've had one built for a client. The thing is you gotta run the node software for each coin you accept.

So for Bitcoin for example. You run a Bitcoin node locally. Then there's a programming interface on that node. So when a customer needs to pay, your payment system talks to the Bitcoin node and requests a Bitcoin address. The node gives it to you. You save that address to the customer invoice. You then wire the Bitcoin node to monitor the address. When a payment comes into that address, the node signals your callback hook, your hook tells the payment system ow much has been deposited. You check it against the invoice and if OK you mark it paid after 3 confirmations (30 minutes). That's all there is to it.

Key points here

You need to keep this Bitcoin node running 24x7

And if your customer database is huge, the node address database hogs down rather quickly. You then need to scale it using custom solutions. Which is where I left the project, but pretty sure they outsourced it after a few years.

I've been building it for hours. Well, Claude has been building it, I've just been tingling his balls

It's ready, almost.

Coingecko for price/crypto, Etherscan for monitoring if payment has arrived, 60 minute window for client to send crypto from the moment they initiate a payment. Overpayments and underpayments dealt with manually.

I just did ETH-related chains for now, a few of them. Will expand to BTC and SOL and a few others once I confirm this all works...

If anyone wants to check it out, PM me (only trusted members with gigantic penises allowed) hahaha


Edit: to check my custom crypto gateway will require KYC and KYB. So you'll have to send a photo of you standing on your head, fully erect, one hand holds a ruler to confirm gigantism, another thumb in your mouth. Set your camera to take a photo after 30 seconds and put yourself in position

Yeah it was nice I had a good time with it.

I mean, it's stored safely and securely and used only for verification purposes. It's is certainly NOT used for sexual deviant purposes. You can trust our company, dear sir

Wanna check out my amazing crypto payment processor that's gonna out-compete them all and land me in prison for 100,000 years?
