In a transaction that eventually calls revert(), if prior to the revert we have SELFDESTRUCT some contracts and thus received a gas refund, does the gas refund also get reverted?

An interesting question! I could not find anything in the docs about this, but I also couldn't find anything about selfdestruct's gas refund (until I noticed this How do gas refunds work? ).

I did some experimenting with the following contracts:

pragma solidity ^0.7.0;

contract A {
    function die() public {

contract B
    A aRef;
    function init() public {
        aRef = new A();
    function killIt() public {
        uint i;
        for (i = 0; i < 10000; i++) { }

So what I did was:

  1. Deploy B
  2. Run init
  3. Run killIt

I checked the gas costs in two cases:

  1. Executing just like I pasted above. The call to killIt costs 588914
  2. Executing with line aRef.die(); commented out. The call to killIt costs 581421

Obviously the selfdestruct's gas refund is not applied here so the refund is wasted.


A gas refund is only applied at the end of a transaction. Any state changes are reverted immediately when a transaction is reverted, so only the remaining gas for the transaction is refunded. That means that the gas refund is also reverted.
