🗄️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:

• All Categories

• Criminal Categories

"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.
