Build a demo dApp to send Ethereum RPC over HOPR

SCBuergel commented 1 year ago

Job Story

HOPR has built Playground which allows anybody to try out the HOPR protocol without the need to install anything. Playground currently supports many HOPR compatible dApps, many of them found in the hopr-community repository.

We would like you to build a new dApp that will be featured on Playground and allow a node to send and receive Ethereum RPC traffic. This dApp is meant to be used for demonstration purposes and be utilized in upcoming hackathons.

Description

In this dApp, a user should be able to connect to a HOPR node. Once the HOPR node receives a message and is relayed to the dApp through the API, the dApp must parse and recognise whether the message is an Ethereum RPC request. Afterwards, the dApp submits the Ethereum RPC request to a working Ethereum RPC provider and sends back the response. HOPR Relay can be used as an example, with the main difference being that HOPR Relay runs on a nodeJS instance instead of a browser window.

In terms of UI, we would like to show a list of requests and responses and a small status indicator for each of them that it was sent successfully.

Some things to take into consideration:

The response to the request must be sent back to the sender
Messaging format should specify the chain ID that is being used
Use a compression library such as GZIP to compress requests and responses
Large responses (>500 bytes) should be segmented (naive is ok, see https://github.com/janmaslo/Secourier or https://github.com/vanoob404/hopr-fsdapp for inspiration)

Out of scope:

The ability to verify that the message was sent by the sender and vice versa

Deadline

This dApp must be completed by 23/09/2022. The applicant is expected to give regular updates.

Definition of Done

A dApp is available which can be hooked into a HOPR node (via Playground). Once it receives an Ethereum RPC request it forwards it to a working Ethereum provider and sends back the response.

Hi there HOPR team! I would like to work on this bounty by creating an example dApp that can send Ethereum Remote Procedure Calls over HOPR mixnet. 2) manyrios has applied to start work _(Funders only: approve worker | reject worker)_.

Build A Demo DApp To Send Ethereum RPC Over HOPR with all the requirements. It will be able to send it in playground without install anything 3) bshevchenko has applied to start work _(Funders only: approve worker | reject worker)_.

Ready to start with this one ;) 4) soptq has applied to start work _(Funders only: approve worker | reject worker)_.

Hi, I have go through the documentations and ready to work on. Will provide a working project before ddl if approved. 5) vividwood has applied to start work _(Funders only: approve worker | reject worker)_.

I'll study HOPR Relay code first and then implement it in browser. Will be glad to work with you again :) 6) vanoob404 has applied to start work _(Funders only: approve worker | reject worker)_.

I had experience working with ethRPC and HOPR too. I think I can get this dApp ready. 7) cnoveron has applied to start work _(Funders only: approve worker | reject worker)_.

Hi nionis,

I would start by validating assumptions in order to get the requirements right regarding aspects like, for example, the messaging format. I suppose this is going to be a RESTful JSON API, so, I assume the payload can be a valid JSON with just data and chainId, but that might not be what you are interested in.

Once I have fully validated the requirements, I'll proceed to put up a simple NodeJS server, add endpoints to it. (I have designed APIs in the past using Express or Hapi.js, and GZIP to compress the requests and responses. So, that won't be a problem.) After that I will integrate HOPR functionality.

One last question is wether I should be storing anything in DBs or Firebase...

I hope you can find value in my experience.

Best regards, Carlos

Sorry I will not be able to complete this project... I m busy these days and will be busy for more 3-4 days.

It is a bit tricky project though. I m excited to see what others have done.

I am seeking more opportunities to work with you.
