Ethereum proposals seek to stop Glamsterdam from breaking old contracts
The two rival EIPs use different methods – one changes contract visibility, the other adjusts user fees – to protect legacy smart contracts.
Key takeaways
- 1Two competing EIPs were submitted to address the Glamsterdam upgrade
- 2Ethereum’s market cap stands at about $262 billion as of 9 Nov 2026
On 9 November 2026, two competing Ethereum improvement proposals were submitted to stop the upcoming “Glamsterdam” upgrade from breaking existing contracts. The proposals target the planned gas‑cost changes that could render legacy smart contracts inoperable.
One proposal rewrites the gas‑metering logic so contracts see the same execution environment as before, while the other adjusts the fee model so users pay the intended amount without triggering failures. Both aim to preserve continuity, but they differ on whether the change is applied at the protocol level or through transaction pricing.
Ethereum, the world’s second‑largest cryptocurrency, trades at $2,142.85 with a market value of $261.9 billion, according to YourKhabri data on 9 Nov 2026. The platform powers thousands of decentralized applications and has previously rolled out upgrades such as London and Shanghai that altered fee structures. Compatibility concerns have arisen before, prompting the community to vet changes through EIPs.
If either proposal is adopted, legacy dapps should continue operating without costly rewrites, reducing risk for ordinary holders. The debate shows the network’s focus on stability as it scales. Traders will watch the Ethereum core‑dev meetings for a final decision and monitor client releases for implementation details.
