Assets with a maximum supply that cannot be increased, so holders are not diluted indefinitely by new issuance. 674 of the 929 assets in the directory qualify.
A hard cap means the number of units is bounded and dilution eventually stops. It says nothing about demand, and plenty of capped assets have gone to nothing. What it removes is one specific way of losing money slowly: holding something whose supply grows faster than its usage.
Showing the 120 highest scoring of 674 that qualify. The rest are reachable through the A to Z index and the sector pages.
There are no prices or market caps here, deliberately. Those numbers are stale within hours of being written, and a directory full of stale numbers is worse than one without them. What is recorded instead is structural and durable: what the thing actually does, how its supply behaves, who can change it, whether the token captures any revenue, and what has happened to it. For live prices use an exchange or a data aggregator.
