How to receive tips in a NSFW website?

I've been trying to find a way to receive small tips in a NSFW site. Payment processors like Paypal or Stripe are out of the question. I know crypto is one option, but not many users have crypto wallets and stuff, and the transaction fees can be quite high sometimes. Platforms like buymeacoffe or ko-fi do not allow sites with NSFW content. I found Throne but that's more like a wishlist. Subscribestar has monthly subscriptions but not one-time tips.
Does anyone know how to get tips on a +18 site? I will appreciate any ideas or suggestions.

Just do you own placeholder "superchat" website if you are big enough.

I'm not familiar with "superchat", it just looks like a messaging platform. Do they allow tips/donations? Could you please explain a bit more?

How viewers of streamers get paid from superchats?

They pay somewhere, "send superchats" or "donate here" website.
If you are big enough copy the model. You -> Your Superchat/Donation Service -> Stripe.

If you don't get it, please ignore me.

IMO, tipping on a porn (NSFW 18+) site isn't a great monetization method unless you have a very specialised niche.

Look at :

Did you find any option?
