Needs a "withSIWE" method (similar to how NextJs has both useRouter and withRouter)

[FFdhorkin]

I have a Next.js Server Action that needs to validate a user is signed in as a specific user.

As things currently stand, I don't think there's a way to do this. You can't use a React hook inside a server action since it isn't a React component. the siweServer has a getSession method, but this expects you to have access to the req/res, which you don't in a server action.

My specific use case: I have a server action that handles when a user clicks on a button. If a user is either not SIWE signed in OR they are signed in but not the correct user, it needs to throw an error.

The only thing I can think of is what I was doing before I switch to using connectkit, when I was using iron-session to store the SIWE cookie and manually pulling the cookie, e.g. I used to have:

    async getAuth(): Promise<IronSessionData | undefined> {
        if (cookies().has('siwe')) {
            const siwe = cookies().get('siwe');
            if (siwe !== undefined) {
                return unsealData<IronSessionData>(
                    siwe.value,
                    { password: getSecret() }
                );
            }
        }
        return undefined;
    }

and then a server action that included:

'use server';

import { SiweMessage } from 'siwe';

import { getAuth } from './getAuth';

async clickHandler(
    localUserAddress: Address,
    authToken: Signature
) {
    const siwe = (await getAuth())?.siwe;
    const isSignedIn = siwe !== undefined
        ? (await new SiweMessage({ ...siwe, address: localUserAddress }).verify({ signature: authToken })).success
        : false;

But given the connectkit docs don't talk about how SIWE cookies are stored behind the scenes, this feels at best like a brittle approach that might break in a future version of connectkit. And it would require me reverse-engineering connectkit code to figure out exactly how the cookie is accessed.

Surely there's a better way than this?

I'd love to be able to go

'use server';

import { siweServer } from "@/utils/siweServer";

async clickHandler(
    localUserAddress: Address,
    authToken: Signature
) {
    const isSignedIn = siweServer.isCurrentUser(localUserAddress);

or something to that effect.
