Erc 677 license
Overview
ERC-677 is a proposed Ethereum token standard that extends ERC-20 with a transferAndCall function. This function enables tokens to be sent to a contract and simultaneously trigger logic within that contract in a single operation. When transferAndCall is executed, the token transfer occurs and the recipient contract's onTokenTransfer function is called with accompanying data, eliminating the need for a separate approve-then-call workflow. The standard is backward compatible with ERC-20. Chainlink's LINK token is the most prominent implementation of ERC-677, allowing oracle contracts to respond immediately to LINK payments.

Questions on the record
What does transferAndCall do?
The function sends tokens to a designated address and, when that address is a contract, invokes its onTokenTransfer function along with supplementary data, all within a single transaction.
