= ERC 777
[.readme-notice]
NOTE: This document is better viewed at https://docs.openzeppelin.com/contracts/api/token/erc777
CAUTION: As of v4.9, OpenZeppelin's implementation of ERC-777 is deprecated and will be removed in the next major release.
This set of interfaces and contracts are all related to the https://eips.ethereum.org/EIPS/eip-777[ERC777 token standard].
TIP: For an overview of ERC777 tokens and a walk through on how to create a token contract read our xref:ROOT:erc777.adoc[ERC777 guide].
The token behavior itself is implemented in the core contracts: {IERC777}, {ERC777}.
Additionally there are interfaces used to develop contracts that react to token movements: {IERC777Sender}, {IERC777Recipient}.
