Ethereum Developers Sound Alarm Over L1 Contract Risks Ahead of Major Gas Overhaul

Summary

• Ethereum’s proposed gas repricing could expose contracts relying on fixed gas assumptions, although most applications should remain unaffected by Glamsterdam’s changes.
• Mainnet transaction tests found limited compatibility issues, with some contracts needing higher gas limits while others require deeper code changes.
• EIP-8037 and EIP-8038 target more accurate state costs, supporting Ethereum’s capacity goals while developers test contracts before deployment.

 

Ethereum developers have warned that some L1 contracts could face problems under Glamsterdam’s planned gas repricing. According to the Ethereum Foundation, EIP-8037 and EIP-8038 will change costs for creating and accessing state.

The changes could disrupt contracts that depend on fixed gas values or execution assumptions. However, developers said most Ethereum contracts should remain unaffected by the planned repricing. Mainnet transaction tests identified a small group of contracts that could break or experience degraded performance.

Ethereum Gas Overhaul Could Expose Hardcoded Contract Assumptions

EIP-8037 and EIP-8038 aim to make gas prices better reflect resources required for different state operations. Ethereum last adjusted state-operation pricing during the Berlin upgrade in 2021.

Since then, Ethereum’s state has expanded significantly as applications stored more information across the blockchain. Consequently, developers want state-related costs to better match the resources consumed by these operations.

The Ethereum Foundation replayed historical mainnet transactions under the proposed Glamsterdam pricing schedule. Most transactions produced identical outcomes, while some required different gas limits under the proposed rules.

Additionally, affected contracts could resolve their problems by increasing their gas limits. However, a smaller group still failed despite higher limits, indicating deeper compatibility issues.

According to the Foundation, some contracts rely on hardcoded gas assumptions that the repricing could invalidate. These assumptions can involve fixed gas values, Solidity’s 2,300-gas stipend, or logic that depends on remaining gas.

The Foundation has started contacting builders associated with affected contracts. Meanwhile, developers can test contracts against the proposed schedule before Glamsterdam reaches Ethereum mainnet.

Platåberget provides an environment for identifying compatibility problems linked to the upgrade. The gas changes are part of Ethereum’s effort to increase Layer 1 capacity.

The schedule supports targets that could enable three times base throughput. Therefore, developers view repricing as an important step before raising the network’s gas limit further. Glamsterdam combines execution and consensus layer changes under one Ethereum upgrade.

Conclusion

Ethereum developers have identified L1 contract risks from Glamsterdam’s gas overhaul. Most contracts remain unaffected, but builders using hardcoded gas assumptions may need updates before mainnet deployment.
