21Cash is the affiliate program for 21Sextury Network, a Budapest-based production company with a catalog of European-shot explicit paysite content spread across a dozen properties covering multiple niches. The program offers both PPS and revshare commission options, with bi-weekly payouts and a standard suite of hosted promotional materials. The European production quality and the variety of properties under one login give affiliates a reasonable breadth of content to match against different traffic segments.

The brand is well-known in European affiliate circles but less dominant in North American traffic; conversion will vary meaningfully by geo, so testing before scaling is advisable.
