Katalogos is the directory. It reads the wallet's registry and shows every asset it can hold — backed assets (MBAs) at one end of the spectrum, non-backed assets (NBAs) at the other, each with the parameters the chain has sealed.
Filter by class, filter by use-case (currency, share, points, wrapped), sort by category or backing rate, favourite the ones you follow. Adding a new asset happens through Pinax, the registration sheet — paste a JSON definition or fill the form, and the wallet validates the contract addresses and fee against the chain before it lands in your Katalogos.
What you see is what the chain settled: no editorial gate, no promoted rows. Adding an asset carries a small listing fee (paid through Pinax); the founder pays for genesis; Katalogos then surfaces the asset to whoever imports it.
