  124. This set of interfaces and contracts are all related to the https://eips.ethereum.org/EIPS/eip-6909[ERC-6909 Minimal Multi-Token Interface].
    125. 

  125. 

  126. The ERC consists of four interfaces which fulfill different roles--the interfaces are as follows:
    127. 

  127. 

  128. . {IERC6909}: Base interface for a vanilla ERC6909 token.
    129. 

  129. . {IERC6909ContentURI}: Extends the base interface and adds content URI (contract and token level) functionality.
    130. 

  130. . {IERC6909Metadata}: Extends the base interface and adds metadata functionality, which exposes a name, symbol, and decimals for each token id.
    131. 

  131. . {IERC6909TokenSupply}: Extends the base interface and adds total supply functionality for each token id.
    132. 

  132. 

  133. Implementations are provided for each of the 4 interfaces defined in the ERC.
