Ethereum Developers Propose Fixes to Prevent Glamsterdam Upgrade Contract Failures

Two competing draft proposals emerge to address potential smart contract failures in Ethereum's Glamsterdam upgrade, which threatens to break 200,000 existing applications due to sharp gas fee increases.

Ethereum's Glamsterdam upgrade would raise the contract-creation charge from 32,000 to 183,600 gas under EIP-8037, risking failures in up to 200,000 affected contracts that cannot be updated. Security concerns already forced a postponement of the Oct. 26 testnet rehearsal, and the two rival fixes, EIP-8488 and Rebuffo's draft, are unimplemented drafts with no target date. Prolonged uncertainty and delay around the network's next major upgrade weigh on confidence in ETH, though the risk is to a future upgrade rather than to the current chain.

Catalysts
  • ▼ Next private Glamsterdam test estimated Oct. 29 for Nov. 16 to 20 at the earliest
  • ▼ Competing fix drafts EIP-8488 and Rebuffo's two-meter proposal remain open with no target date
Risk Factors
  • ▲ Second testnet rehearsal already postponed after security researchers raised the alarm
  • ▲ Rebuffo's draft admits no execution-client implementation or consensus tests have been run

🧭 Full analysis of these assets

🎯 Key Takeaways

  • EIP-8037 proposes raising the base charge for creating an Ethereum contract from 32,000 to 183,600 gas.
  • Security concerns regarding the upgrade led to the postponement of a testnet rehearsal originally scheduled for Oct. 26.
  • Developer banteg identified at least 200,000 affected contracts, noting that the actual number of impacted protocols is likely higher.
  • Proposed fixes EIP-8488 and Rebuffo's draft remain in early stages with no execution-client implementation, consensus tests, or target dates.

📝 Executive Summary

Ethereum developers are scrambling to address risks posed by the upcoming Glamsterdam upgrade, which could break up to 200,000 existing smart contracts. Proposed gas fee hikes under EIP-8037 would raise contract creation costs from 32,000 to 183,600 gas, threatening apps that cannot be updated. Two rival draft proposals, EIP-8488 and a design by Giulio Rebuffo, aim to mitigate these failures, though neither has a target implementation date.

❓ FAQ

Could Ethereum apps actually break?

Possibly: gas costs for creating and touching stored data would rise sharply (contract creation from 32,000 to 183,600 gas), and apps that pay fixed gas amounts and cannot be updated could see their calls fail. Around 200,000 affected contracts have been listed, and one researcher says the true number is higher.

Is a fix already in place?

No. Two competing draft proposals exist: one keeps legacy gas rates for existing contracts, the other charges new rates but uses separate accounting so old apps keep running. Neither has an implementation, consensus tests or a target date.
