Whenever an exchange facilitates trading pairs for a certain asset, this is referred to as "listing" the asset. In traditional markets, this indicates that a company's shares (or other material asset) are available for trading on that certain stock exchange. In general, this means that the company being listed has met specific financial and regulatory viability standards, as well as a level of trust from the exchange. Thus, by listing, the exchange indicates that the shares of the company/asset are known to be of a required level of quality.
