Would you be able to put couple of asserts here?

[mandrigin]

@tsutsu please also update the REAMDE for rpcdaemon and include the new API method

[tjayrush]

Should this be in the eth_ namespace? I feel like that will come back to haunt you at some point. Isn't the eth_ namespace reserved for things available across multiple clients and maybe even requiring an EIP? I did a quick Google search. I didn't find it elsewhere. Maybe I missed it.

I agree; this isn't a standardized endpoint (and in fact wouldn't be supportable in other clients due to only being practical with a ChangeSet-like index) so shouldn't be under eth_. Wasn't sure of the correct namespace to put this under. Will change to whatever is suggested. (And will then update the README to mention.)

@tsutsu let's add real test asserts and move it to erigon_ for now

[mandrigin]

(1) add assets to this tes
(2) move to erigon_ namespace

Here are some assertions: 25be3d6
Are they sufficient?

I will add line to cmd/rpcdaemon/readme.md

@mandrigin let's merge?

[mandrigin]

Done!
