Async is an online platform for buying and selling tokens representing certain rights to interact with programmable art and media on the Site (“Tokens”). Creative Works (as defined below) include, but are not limited to, visual artworks, audio artworks, Musical Works (as defined in the Music Supplement to Terms of Use), audiovisual artworks, or other creative works, and are of two kinds: (1) Creative Works consisting of a series of alternative versions or components of an image and/or audio file that are intended to be used as a component part of a complete, standalone Creative Work (each such image(s) and/or audio file(s), a “Layer”) and (2) complete, standalone Creative Works, which may be indivisible and non-modifiable or may consist of a combination of Layers and be modifiable through selection of which image and/or audio file of each Layer is presented within such Creative Work at a given time (each such Creative Work, a “Master”). Each Master or Layer may be represented in the form of non-fungible ERC721 digital assets (“Master Token” and “Layer Token,” respectively) that themselves may be created by reference to a smart contract on the Ethereum blockchain created by Async (“Smart Contract”). The Site will present either the Master or Layer(s) of a Creator (collectively and individually, the “Creative Work”) and individuals can browse Creative Works and purchase Tokens associated with a Creative Work (the availability of these Services on the Site shall be referred to as the “Marketplace Services”). The Site provides a rendering service to allow you to view and/or listen to the Creative Work  and allows the holders of Layer Tokens to configure the corresponding Layers within each Master that includes the corresponding Layers, thus affecting the manner in which each Master is presented (“Rendering Services”).
