Ethereum Glamsterdam hard fork to end fixed 21,000-gas rule

Ethereum Foundation has warned developers of wallet services, gas-fee calculators and blockchain explorers ahead of the upcoming Glamsterdam hard fork, as the long-standing rule of thumb that a simple ETH transfer always costs 21,000 gas will no longer universally apply, CoinDesk reported. Transfers to existing addresses will still require 21,000 gas, but transfers to new addresses will incur an additional state gas fee of about 183,600 because the network must create and permanently store new state data. Many existing crypto wallets and trading services are designed to hard-code ETH transfer fees at 21,000 gas or estimate costs along a single gas dimension, so after the upgrade, transfers to new addresses could be rejected or fail because of gas-limit overruns or insufficient fees. CoinNess previously reported that the Glamsterdam upgrade, which had been scheduled for the first half of the year, was delayed to the fourth quarter.
