Assumes EIP-7954 is merged. Beyond the 32KiB threshold: - Standard region (0-32KiB): 200 gas/byte (unchanged) - Extended region (32-64KiB): 500 gas/byte (per EIP-2926) - Max deploy cost: ~23M gas for 64KiB contract - Initcode limit: 128KiB (2:1 ratio preserved)
Extended region surcharge is per 31-byte chunk, not per byte: - Standard deposit (200/byte) applies to ALL code - Beyond 32KiB: additional ceil((N-32768)/31) * 500 surcharge - 64KiB deploy: ~13.6M gas (6.5M standard + 529K chunk surcharge) - Constants from EIP-2926: CHUNK_SIZE=31, 500 gas/chunk

Wait. It was already agreed to bump to Glamsterdam to 32KBs (basically relying on the data I provided and presented in https://ethresear.ch/t/data-driven-analysis-on-eip-7907/23850 and in ACD). So as from Glamsterdam, the "baseline" is 32kBs. Wasn't at the end your EIP the one that was included directly? |

The commit dfb002d (as a parent of 2fe18b1) contains errors. |

Summary
Proposes raising the maximum contract code size from 24KiB to 64KiB and the initcode size from 48KiB to 128KiB.
0x6000) → 64KiB (0x10000)0xC000) → 128KiB (0x20000)The 64KiB boundary (2^16) is a natural power-of-two that aligns with common memory page sizes. The economic cost of deploying larger contracts scales proportionally via calldata and initcode word costs, acting as a natural deterrent against abuse.
Modifies: EIP-170, EIP-3860
