@s1na I see @rjl493456442 assigned you to this, lmk if you'd like any changes or if I should just close, thanks

There are 2 points about this PR:

• We first need to agree with other clients whether to add this field.
• The implementation: the applyMessage result already contains the maxUsedGas field. You can use that.

@Rhovian so how it works is we need to update the spec here to add the field: https://github.com/ethereum/execution-apis/pulls

And then ask clients e.g. in Eth r&d discord json rpc channel whether they are onboard with adding it.

hey @s1na happy to make the PR and adjust this one as needed but i would hope to leave client consensus up to you as im not connected

[s1na]

@Rhovian I can help with that

hey @s1na made the change you mentioned (using the result from applyMessage) and moved this along here:

ethereum/execution-apis#746
