Add ERC: Universal Orchestrator RPC #778

IAmKio · 2024-12-16T23:33:22Z

Abstract

The Universal Orchestrator RPC aims to standardise the universal shape and requirements of a request for a solution from an arbitrary system managing an Ethereum wallet to, ultimately, an Orchestrator.

An arbitrary system could be a website, device, app, server program etc - anything that manages an Ethereum wallet, speaks Ethereum JSON-RPC and is looking to request solutions from an Orchestrator.

All solutions from an Orchestrator are ChA¹ (Chain Abstraction-first) by default.

+title: Minimal Orchestrator RPC


While there's no hard rule against it, I would recommend not using "minimal" in your title/description. The definition of minimal is extremely subjective and the term doesn't really provide useful information to readers. It would be better to highlight characteristics of your proposal that would differentiate from similar hypothetical proposals.

Understood - the name has been changed to Universal Orchestrator RPC. Just a note, i'm currently doing research to figure out if the term Orchestrator is still current.

We have a slight preference for SVG images, if you can provide them. If not, PNGs are fine too.

Unfortunately the tool i used, swimlanes.io - only exports in PDF or PNG. My apologies.

We like to avoid mentioning specific products in proposals. It unfairly advertises projects that exist today over ones that come after going final.

Agreed - this has been changed. Thanks.

Reserve backticks for inline code. The RFC 2119 key words should be unformatted uppercase.

It is unclear what "prefer chain abstraction" means.

I have added an explanation for clarity.

Ahh understood - thanks, i'll check the rest of the document for this also.

+#### RPC


This section seems to be re-explaining JSON RPC. I'm not sure how necessary it is.

Whilst i understand what you're suggesting - for the sake of being clear and completion, i would prefer to leave this here to make it crystal clear that this is an Ethereum RPC request and that the params property is a Problem[].

I'm not sure this'll render the way you want. Double check it after merging.

Sorry you're right i was using a reference from elsewhere. I have now changed it to the alert standard here: https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#alerts
