1//! Constants for [EIP-7708](https://eips.ethereum.org/EIPS/eip-7708): ETH transfers emit a log.
2//!
3//! This EIP specifies that all ETH transfers (transactions, CALL, SELFDESTRUCT) emit a log,
4//! making ETH transfers trackable like ERC-20 tokens.

8/// The system address used as the log emitter for ETH transfer events.
9///
10/// This matches the ERC-20 Transfer event format but uses a system address
11/// as the emitter since no contract actually emits these logs.

13    address!("0xfffffffffffffffffffffffffffffffffffffffe");

15/// The topic hash for the Transfer event: `keccak256("Transfer(address,address,uint256)")`.
16///
17/// This is the same topic used by ERC-20 tokens for transfer events, ensuring
18/// compatibility with existing indexing and tracking infrastructure.

21
22/// The topic hash for self-destruct to self events.
23///
24/// This is emitted when a contract self-destructs to itself, which doesn't
25/// involve an actual transfer but still needs to be logged.
