Be able to use shanghai compiled contracts on a PoA testnet that is not from --dev

[antazoey]

Rationale

Why should this feature exist?

Because we have features that rely on it.

What are the use-cases?

Having a test provider with excellent transaction tracing support such debug_traceTransaction that is built from the same package as actual nodes. We have been providing this as an option and the best thing it has helped us over the years is testing all tooling related to traces.

As PUSH0 / shanghai came about, things aren't working on our PoA testnets without using older versions of EVM to compile, which can be a pain.

Implementation

Do you have ideas regarding the implementation of this feature?
I just need it to "work" more than I need it to be chain-accurate, I really have no idea.

Are you willing to implement this feature?
I don't know how capable I would be otherwise yes, though I am also not sure how much time I will be able to find. If it really came down to it, then yes I would try, unless it really is impossible.

the related ticket is here: #27365
that added support for --dev.

however, I am not able to use --dev because it does not let me configure genesis enough.

If you are trying to use Shanghai features on a private testnet, enable the Shanghai fork in your genesis configuration.

If you are trying to use Shanghai features on a private testnet, enable the Shanghai fork in your genesis configuration.

I added "shanghai": 0, with all the other forks, however I still get (-32000) invalid opcode: PUSH0

The field you want is shanghaiTime

Thank you! I apologize for my noob-id-ity.

@antazoey Hi, I also have same the issue. Did you upgrade to Shanghai`? I had a private network with POA consensus (use Clique). I want to upgrade Shanghai for my network, but after investigating, it doesn't support it. I received the error when run network.

@antazoey Hi, I also have same the issue. Did you upgrade to Shanghai`?

this is what we are doing:

https://github.com/ApeWorX/ape/blob/main/src/ape_geth/provider.py#L99-L122

this is the version of geth we are using:

@antazoey How many nodes have you run for your private network? Have all of them been upgraded to Shanghai?

Hi, when I enabled Shanghai in the POA private network, I received the error #29319. The Shanghai doesn't work in POA, right?
