Ethereum’s Glamsterdam upgrade rewrites the ‘21,000 gas’ rule that wallets have used since day one

For as long as Ethereum has existed, sending ETH from one wallet to another has cost exactly 21,000 gas. It’s been one of the few constants in a protocol that has otherwise reinvented itself multiple times. The Glamsterdam upgrade is about to change that. Under the new rules introduced by EIP-8037, transfers to existing accounts will still cost the familiar 21,000 gas. But any transfer that creates a new account on the network will now incur additional state gas charges, effectively splitting Ethereum’s gas model into two tiers for what used to be a single, uniform operation. What’s actually changing and why it matters The core issue is deceptively simple. Every time someone sends ETH to a fresh address that has never appeared on the blockchain before, Ethereum has to create a new entry in its global state database. That state entry lives on the network forever, occupying storage that every full node must maintain. Until now, the cost of creating that entry was bundled into the same flat 21,000 gas fee as a transfer to an address that already exists. The new gas structure proposes a floor of 200 million gas, designed to cap state growth in a way that keeps the network sustainable a...
