LINK Token Contracts
LINK tokens are used to pay node operators for retrieving data for smart contracts and also for deposits placed by node operators as required by contract creators. The smallest denomination of LINK is called a Juel, and 1,000,000,000,000,000,000 (1e18) Juels are equal to 1 LINK. This is similar to Wei, which is the smallest denomination of ETH.
The LINK token is an ERC677 token that inherits functionality from the ERC20 token standard and allows token transfers to contain a data payload. Read more about the ERC677 transferAndCall token standard.
