IERC777Recipient contract

Interface of the ERC777TokensRecipient standard as defined in the EIP.

  • Accounts can be notified of {IERC777} tokens being sent to them by having a contract implement this interface (contract holders can be their own implementer) and registering it on the https://eips.ethereum.org/EIPS/eip-1820[ERC1820 global registry].
  • See {IERC1820Registry} and {ERC1820Implementer}.

Functions

tokensReceived

Called by an {IERC777} token contract whenever tokens are being moved or created into a registered account (to). The type of operation is conveyed by from being the zero address or not. * This call occurs after the token contract's state is updated, so {IERC777-balanceOf}, etc., can be used to query the post-operation state. * This function may revert to prevent the operation from being executed.
