Offer anvil_metadata RPC

[antazoey]

Component

Anvil

Describe the feature you would like

I would like the same feature from Hardhat as this: https://hardhat.org/hardhat-network/docs/reference#hardhat_metadata
This way, I can easily perform verifications on the forked network without relying on genesis block hashes or anything weird.

It is useful metadata at the node level in general.

Additional context

No response

sgtm!

we can easily add this, will do if no one picks it up

Doesn't anvil_nodeInfo already returns the info that you need?

foundry/crates/anvil/src/eth/api.rs

Line 1662 in 86f3d18

pub async fn anvil_node_info(&self) -> Result<NodeInfo> {

[mattsse]

metadata includes more info and NodeInfo is standard format

we can just add a new type + call

[antazoey]

All I am really doing is checking to see if the connected is a fork; I supposed to existence of forkConfig in anvil_nodeInfo may accomplish that.

One nice thing about the metadata response is the chain ID being present instead of me having to make another request to get it.

fyi @Evalir this would be super simple to add

[Evalir]

yep there's utility to this, so let's go and add it
