Module eip8038 

EIP-8038: State-Access Gas Cost Update

Increases the gas cost of state-access operations to reflect Ethereum’s larger state. The values below are the parameters proposed in ethereum/EIPs#11802 (still a draft — treat as preliminary), superseding the earlier previous_value + 1 placeholders.

Active alongside EIP-7904 and EIP-8037 starting at the Amsterdam hardfork.
