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 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.

LINK is native to Ethereum, so to use LINK on other chains, it must be bridged. This guide explains how to bridge and swap tokens to other chains.
Important
The LINK provided by the BNB Chain Bridge is not ERC-677 compatible, so cannot be used with Chainlink oracles. However, it can be converted to the official LINK token on BNB Chain using Chainlink's PegSwap service.
