EIP-7708 (ETH Transfer logs):
- Label events from 0xfffffffffffffffffffffffffffffffffffffffe as
"ETH Transfer (EIP-7708)" in the events tab index column badge.
- Detection in buildEventsFromBlockdb: compares source address bytes
against the ETH Transfer logger address.
EIP-7976 (calldata floor cost):
- Pre-compute CalldataFloorGas = 21000 + 64 × len(calldata) in handler.
- Show "EIP-7976 floor: N gas" badge next to Gas Used in the tx overview
whenever the transaction has non-empty calldata.
- Tooltip explains the formula and the Amsterdam change.

For logs emitted by the ETH Transfer logger (0xfff...ffe), decode the Transfer(address,address,uint256) parameters from topics and data: Topic1[12:32] = from address Topic2[12:32] = to address Data[0:32] = uint256 wei amount → formatted as "X.XX ETH" Display a highlighted summary box in the events tab showing the decoded from/to addresses (linked to /address/...) and the ETH amount. Also add a green ETH amount badge in the event index column. This makes it easy to see which addresses transferred ETH and how much, without decoding raw hex topics by hand.
