where did 68 come from? seems like magic number

I think that's an estimate of the overhead data of a tx, mostly coming from its signature?

In some places the 68 is hardcoded, to estimate cost before signing. But after the tx has been signed and encoded there's no need to add the 68. So it completely depends on context whether or not it's a necessary addition.
it has been merged to impl, so it seems we must https://github.com/ethereum-optimism/optimism/blob/6d9d43cb6f2721c9638be9fe11d261c0602beb54/packages/contracts-bedrock/src/L2/GasPriceOracle.sol#L236-L250 |
