- Gas-rule dispute could disrupt Ethereum contracts in Glamsterdam — this brief
Ethereum’s upcoming Glamsterdam upgrade could affect as many as 200,000 smart contracts if its proposed gas-calculation changes break existing functionality, according to Cointribune. Developer banteg reportedly warned that some deployed contracts could stop working properly under the new rules.
Two competing proposals were submitted on November 8 to address the compatibility concerns. The scope of the competing approaches was not detailed in the available report, while the developer warning focused on the risk posed by the planned gas-calculation changes.
Cointribune is the only outlet included in the coverage, so the reported 200,000-contract figure, the existence of two proposals and the Hoodi testing issue have not been independently corroborated. No differing figures or additional competing claims were supplied for comparison.
The Ethereum Foundation has already suspended a planned test on Hoodi, adding a testing dimension to the implementation dispute. The central issue is whether the gas-calculation changes can be modified before Glamsterdam proceeds without undermining compatibility for contracts already deployed on Ethereum.
Ethereum was trading at $2,127.76, down 4.31% over 24 hours and 5.30% over seven days, with a market capitalization of $260.04 billion. The broader crypto market was broadly down, with total capitalization at $2.56 trillion, while 
Bitcoin fell 1.08% over 24 hours and the Fear & Greed index stood at 29, indicating fear. The immediate implementation points to watch are the competing proposals and whether testing on Hoodi resumes, rather than any claim that the reported vulnerability has already affected contracts.
Since this brief published about 3 hours ago, Ethereum (ETH) has moved from $2,127.76 to $2,125.12 — -0.12%.
The chart plots ETH's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 ETH ≈ ₦2.94M (about $2,125.12), down 4.2% over 24 hours. The naira itself trades about 2.7% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
