Klaytn native coin - KLAY

KLAY

KLAY is the main internal transferable cryptocurrency of Klaytn and is used to pay transaction fees when creating or executing smart contracts or when transferring KLAY.
KLAY is a necessary element--a fuel--for operating the Klaytn distributed application platform. It is a form of payment made by the clients of the platform to the consensus nodes (CNs) executing the requested operations. To put it another way, KLAY is an incentive; it ensures that developers write high-quality applications (wasteful code costs more) and that the network remains healthy (CNs and RNs are compensated for the resources they contribute).
