Grant Proposal : Sign-In with Conflux


  • Title & Description:
    • Title: Sign-In With Conflux.
    • EIP-4361: Sign-In with Ethereum is a new standard that allows people to use their web3 wallet identity when logging in to web services, as opposed to a username/password pair. Adjust Sign-In with Ethereum to work with Fluent on Conflux Core and with Fluent and MetaMask on Conflux eSpace.
    • Technical Grant, Tier-1
  • Scope:
    • Log-in is a key component in many web services, be it web2 or web3.
    • Instead of asking teams to reinvent the wheel every time, we want to provide an SDK that they can use to implement “Log-In with Conflux” in their apps. See
    • In the short-term, this will allow dapps to implement convenient login flows for their users.
  • Requirements:
    • The existing Log-In With Ethereum stack (SDK) should be forked and adjusted with minimal modifications so it works with Conflux.
    • Also provide an easy-to-follow documentation for projects wishing to use this SDK.
    • The implementation should adhere to EIP-4361 as much as possible.
    • The implementation should be open-sourced.
  • Specifications:


Alone on the project, I’am fullstack developper since 9 years. I already work with SignIn components (Facebook, Google…).
I am familiar with front end and securities constraints

Hi @KCharlemagne, thanks for applying for a Conflux Network grant!

I see for your application you just copied the grant’s description. Are you familiar with SIWE? What would be the main steps to make it compatible with Conflux?

I’d expect the SIWE SDK will work with eSpace/MetaMask with no modification. However, on Core Space with Fluent, the APIs and signing process are a bit different (see CIP-23).

I have read the code of SIWE and no worries about complexity.
The main steps will be

  1. Fork SIWE lib
  2. Forksiwe quickstart for testings in local
  3. Updates SiwcMessage params in SIWE quickstart to map Conflux adresse and Test for MM and eSpace without change SIWE code
  4. Swich Etherum references to Conflux in SIWE, update en adapt code for Fluent compatibility, ajust styles to Conflux theme, build lib in local and link new version in siwe quickstart libs
  5. Test in local and fix potentials bugs
  6. Deploy lib on npm repository

Which name can I choose for the new lib? I think “SIWC” for Sign In With Conflux, and the name is available on npm repo

Thanks, that sounds like a good plan. SIWC sounds good to me.

Let’s wait for some more feedback from other grants committee members. We will make a decision about your application in a week or so.

To summarize the discussion so far: SIWE has multiple SDKs, this grant will focus on the main TypeScript SDK. The plan is to fork and make some minimal modifications so that it is compatible with Conflux Core (Fluent) and Conflux eSpace (MetaMask). It should remain easy to keep the fork up-to-date with upstream changes.

The official quickstart examples should work on Conflux where possible (e.g. we will not support ENS here). Please also provide a simple documentation/article explaining how people can start using SIWC in their apps (with frontend and backend examples).

I approve this application. (fyi: 2 approvals are required, and we will follow up with you after that about the next steps.)


Ok, this steps are also my roadmap. I’m working on it and I have currently no blocking points.
I will provide also a quickstart for SIWC and a documentation

Just a question, do you know what is the equivalent for
in Conflux SDK ?

You might find these usefeul:

I think you’ll need to use ecdsaRecover and compare the addresses.

Congratulations, your application is now approved.
