Sign in with Ethereum, functionally, is connecting a wallet and signing a message. You could add the flow to connect a smart wallet and once connected, the user is logged into the application. Then any user models you have use their smart wallet address as its UUID. Is that helpful?

yeah it is helpful, but I was wondering how the session management on the backend can be implemented in order to avoid session duplication. I am gating something important based on Sign in With Ethereum which is why i need to implement SIWE as securely as possible.

Got it. Those docs aren’t prod ready because they aren’t checking the nonce during verification. Is that the step you need more clarification on? How to check the nonce signature when it’s signed with a smart wallet? Btw, what backend are you using and are you using JWT for sessions?

Currently I haven't written any backend code. But my plan is to have an api route to request nonce and a separate route for verification What I don't know is what after that 😅 just got this link and trying to understand it https://docs.login.xyz/sign-in-with-ethereum/quickstart-guide/implement-sessions
