Get gas back on OKTC#

1. Introduction#

The Gas Back feature allows contract deployers on OKTC to proportionally distribute their contract’s handling fees to other users. After the user deploys a contract on OKTC and registers the contract, they can proceed to receive a handling fee distribution rate (Gas Back rate) according to the system, which will act as a handling fee for any user that calls this contract. Users can directly register this contract by sending an EVM transaction.
