411 projects on Polygon. Each has its own page with the official website, the whitepaper, the social accounts and whatever else the project publishes. A project counts here when its own listing metadata names the chain, or when we found its token trading in a pool on that chain. Plenty of projects run on more than one chain, so they appear under each.
261 with a page that quotes the project's own description, ranked first. Most have no live price with us, so their pages carry links instead of a chart. The other 150 are left off until we have that text; site search still finds them.
