# IERC 1363 Receiver Upgradeable

## Methods

### onTransferReceived

```solidity
function onTransferReceived(address operator, address from, uint256 value, bytes data) external nonpayable returns (bytes4)
```

Handle the receipt of ERC1363 tokens

*Any ERC1363 smart contract calls this function on the recipient after a `transfer` or a `transferFrom`. This function MAY throw to revert and reject the transfer. Return of other than the magic value MUST result in the transaction being reverted. Note: the token contract address is always the message sender.*
