Ethereum Glamsterdam upgrade aims to increase the gas limit to 200 millions, with transfer fees reduced by up to 71%

According to ChainCatcher, the Ethereum Glamsterdam hard fork entered its final development testnet phase on Tuesday, locking in ten EIP proposals, and is positioned as the largest protocol upgrade since the Merge.

The two core proposals are: EIP-7732, which enacts proposer-builder separation (ePBS) directly into the consensus layer, replacing the current reliance on off-chain relays like MEV-Boost; and EIP-7928, which introduces block-level access lists (BALs), allowing validators to process unrelated transactions in parallel. Together, these pave the way for a 200 million Gas limit, approximately tripling the current level of around 60 million, with a theoretical throughput of about 10,000 TPS.

For users, EIP-2780 is expected to make standard ETH transfers up to 71% cheaper. The mainnet activation date has not yet been determined and will require successful validation on the Holesky and Hoodi testnets; based on historical timelines, it is expected to go live between September and December 2026. The 200 million Gas limit is a design goal rather than a mandatory fork value and will be gradually increased by validators through Gas voting signals.
