I have a doubt about the gas refund concept.
Imagine that I created a smart contract 1 month ago and now I want to call the SELFDESTRUCT
because I want to send the current balance to an address and stop using that smart contract. So far I understood that the gas refund will be deducted from the total gas cost of the transaction that is calling the SELFDESTRUCT
, am I right? If not, how is the gas refund "payed"?
