EthereumJS on X: The gotcha: Zero-value transfers → no log. Contract calls with value → yes. Indexers must…

Amsterdam (EIP-7708):

Value-bearing transfers emit a synthetic log in the receipt.

Looks like ERC-20 Transfer(address,address,uint256).
Emitter: the system address (0xff…fe).

Same familiar topic:

Transfer(address,address,uint256)

Your eth_getLogs pipeline can treat native ETH like a token event.

In @ethereumjs/vm:

const result = await runTx(vm, { tx, block })
const logs = result.receipt.logs

No new API beyond Hardfork.Amsterdam.
If the tx reverts → empty logs (as today).

Decode with @ethereumjs/evm:

decodeEIP7708TransferLog(log)
→ { from, to, value }

One value transfer → 1 log in our example.

Burn logs use Burn(address,uint256) on balance-removal paths.

The gotcha:

Zero-value transfers → no log.
Contract calls with value → yes.
Indexers must not assume *only* ERC-20 contracts emit Transfer.

Bloom filters change — watch false positives.

📜 Thread 3 — native ETH finally logs.

Thread 2: every block commits what state it touched.
Today: every native ETH move emits a log you can index.

Status quo (today):

Alice sends Bob 1 ETH.
Balance changes. Receipt has no log.

Indexers infer transfers from traces, internal tx parsers, or balance diffs.

Native ETH is invisible to log filters.

Also: EIP-2780 bundles the transfer log into intrinsic gas (thread 1).

Experimental — not production.

Next: bigger contracts + CREATE2 factory (EIP-7954 / 7997). 🚀
