Ethereum2026-10-08 08:31:01Ethereum’s Glamsterdam clears Sepolia test as gas limit climbs to 200 millionEthereum’s next major upgrade, Glamsterdam, has passed its first formal test after going live on the Sepolia testnet on Oct. 6. Within roughly 11 hours of the fork, Sepolia’s gas limit rose from 60 million to the upgrade’s 200 million target, a level that implies about a 3.3x increase from the current benchmark. Researchers cited in the report described the change as Ethereum’s biggest throughput jump since launch, though the mainnet rollout still depends on more testing and validator choices on gas-limit settings. The upgrade combines the consensus-layer changes known as Gloas with the execution-layer changes called Amsterdam. Among the 18 included Ethereum Improvement Proposals, three stand out: EIP-7732 for enshrined proposer-builder separation, EIP-7928 for block-level access lists, and EIP-7954, which raises the contract size cap from 24 KiB to 64 KiB. The package also reprices state growth. Under EIP-8037, creating a new storage slot would rise from 20,000 gas to 97,920 gas, while a regular ETH transfer to an existing account would remain at 21,000 gas under EIP-2780. The next checkpoint is the Hoodi testnet, where activation has been proposed for around Oct. 27 but is not final. Mainnet is still targeted for the fourth quarter of 2026, after earlier delays pushed both the broader rollout and the Sepolia fork itself.40
