🔥 BREAKING : Ethereum's Glamsterdam Upgrade: Triple Throughput at a Cost
$HEMI $GAIA
Ethereum's proposed throughput boost raises state-creation gas costs dramatically—new accounts jump from 25,000 to 183,600 gas, while storage slots rise from 20,000 to 97,920 gas.
The Trade-off
Goal: ~3x more base-layer throughput
· Cost: Higher gas for new state (accounts, storage, code)
· Why: State grows ~326 MiB/day; repricing aims to cap annual growth at ~120 GiB
The Risk
Replay of 929.7M transactions found: 174.5M fixable with higher gas limits
· 2.7M potentially broken at 10x limits
Hardest hit: Contracts with fixed 2,300-gas stipends, hardcoded gas limits, presigned txs, and ERC-4337 EntryPoint implementations.
Who Must Act
Wallets, RPC providers, bundlers, indexers
· Smart account stacks (ZeroDev, Alchemy)
· Protocols using Across, CoW, 0x, Socket/Bungee
Timeline
Target: Q4 2026 mainnet
· Status: EIPs in Review, testnet dates TBD
· Window: Limited testing before parameters harden
Bottom line: Developers have until Glamsterdam to prove their contracts survive the new cost schedule.
