Ethereum's Glamsterdam upgrade, planned for mainnet activation in Q4 2026, will introduce EIP-8037 and EIP-8038 gas repricing to make transaction costs more closely reflect the computational work involved in creating and accessing blockchain state. EIP-8037 raises and separately meters the cost of creating accounts, storage slots and bytecode, while EIP-8038 increases the cost of operations including SSTORE, SLOAD, cold account access, EXTCODESIZE and EXTCODECOPY. Historical mainnet replays indicate that most transactions would be unchanged or require only minor gas-limit adjustments, but contracts relying on hardcoded assumptions—including Solidity's 2,300-gas transfer and send stipends, fixed call values, gasleft()-based logic or presigned transaction limits—could fail. The Ethereum Foundation has begun contacting affected developers and provides a repricing-impact tool for contract reviews. Developers are urged to test on Platåberget, or glam-devnet-8, launched on August 17, 2026, while wallet, RPC and node-tooling providers update gas-estimation models. The changes are intended to support a potential tripling of Ethereum's block gas limit over time; Ethereum.org considers a post-Glamsterdam limit of 200 million feasible with optimizations including ePBS. Public-testnet deployments to Sepolia and Hoodi are expected in the coming months. Ethereum was trading at $1,624.95 as of August 25, 2026.
