Ethereum's Gas reform is caught in a dilemma, and EIP-8488 proposes a dual-track system for old and new contracts: old contracts remain unchanged, while new rules start fresh.

Ethereum developers have submitted EIP-8488, a draft proposal that would introduce versioned V2 opcodes to enable a dual-track execution environment separating legacy contracts from new ones as part of a long-term gas repricing effort. Contracts deployed before activation would permanently retain the existing gas accounting rules, while all newly deployed contracts would be required to use V2 opcodes and carry a version marker in their bytecode, with cross-contract calls failing unless both caller and callee are V2. The V2 opcode set removes the GAS and GASLIMIT instructions, ending contracts' ability to introspect remaining gas and hardcode system costs into application logic. The proposal follows the Ethereum Foundation's warning that eight contract invariants face breakage risk, and the ACD's decision to delay the Hoodi testnet hard fork, as directly implementing EIP-8037 and EIP-8038 would break existing applications with hardcoded gas logic while shelving repricing risks uncontrolled state growth. The mechanism avoids forcing high-risk refactors of historical assets, letting upgradeable DeFi protocols migrate to V2 implementations over time while immutable contracts keep running under old rules, and once V2 execution share reaches a safety threshold and storage growth is contained, core developers would have the technical basis to raise the network's per-block gas limit substantially. The proposal remains in Draft status and has been placed on the agenda of this week's Ethereum Core Developers Execution (ACDE) call for peer review.
