Description
This PR enables EIP-3529 for BSC on the next hard fork block.
This EIP:
SELFDESTRUCT
.SSTORE
to 1/5th of the gas used in the transaction.SstoreClearsScheduleRefund
from 15,000 to 4,800 .Rationale
Currently the code implementing EIP-3592 is present in the repository, but is not enabled. Moreover, no new tests were added in the pull request implementing it in go-ethereum : ethereum/go-ethereum#22733.
Those tests are added here.
Since EIP-3529 is built upon EIP-2929, this PR also enables EIP-2929. For this a new VM instructionset is defined with both EIPs enabled.
