🗄️Categories
List of categories and their definitions in alphabetical order. Check back regularly for updates.
"Categories" refers to the use-cases for a particular address. Unlike Labels, which refer to the individual and/or entities believed to be associated with an address, "Categories" focuses on what an address is used for:
"Categories" are derived from both public and private sources.
While every attempt is made to standardize categorization, no standardized definitions for many categories exist and "categories" are provided on a “best efforts” basis.
Many addresses, whether contract or wallet, fall into several categories separated by semicolons, given the same address may be used for multiple purposes simultaneously.
