= ERC 721
|
|
|
|
This set of interfaces, contracts, and utilities are all related to the https://eips.ethereum.org/EIPS/eip-721[ERC721 Non-Fungible Token Standard].
|
|
|
|
TIP: For a walkthrough on how to create an ERC721 token read our xref:ROOT:tokens.adoc#ERC721[ERC721 guide].
|
|
|
|
The EIP consists of three interfaces, found here as {IERC721}, {IERC721Metadata}, and {IERC721Enumerable}. Only the first one is required in a contract to be ERC721 compliant.
|
|
|
|
Each interface is implemented separately in {ERC721}, {ERC721Metadata}, and {ERC721Enumerable}. You can choose the subset of functionality you would like to support in your token by combining the
|
|
desired subset through inheritance.
|
|
|
|
The fully featured token implementing all three interfaces is prepackaged as {ERC721Full}.
|
|
|
|
Additionally, {IERC721Receiver} can be used to prevent tokens from becoming forever locked in contracts. Imagine sending an in-game item to an exchange address that can't send it back!. When using <<IERC721-safeTransferFrom,`safeTransferFrom`>>, the token contract checks to see that the receiver is an {IERC721Receiver}, which implies that it knows how to handle {ERC721} tokens. If you're writing a contract that needs to receive {ERC721} tokens, you'll want to include this interface.
|
|
|
|
Finally, some custom extensions are also included:
|
|
- {ERC721Mintable} — like the ERC20 version, this allows certain addresses to mint new tokens
|
|
- {ERC721Pausable} — like the ERC20 version, this allows addresses to freeze transfers of tokens
|
|
|
|
