Ethereum Upgrade Could Break Some Wallets, Indexers

The Ethereum Foundation has warned that some wallets and tools could stop working after the planned Glamsterdam upgrade.

The upgrade, set to deploy on Thursday, introduces a new gas model overhaul under EIP-8037, which adds an extra state-gas charge for transfers to new accounts.

Sending Ether to existing accounts will still cost 21,000 gas, but transfers to new accounts will incur the additional state-gas charge.

The foundation said software that assumes all Ether transfer costs are 21,000 gas must be reviewed and updated immediately.
