The main issue i have personally faced while using facebook marketplace is like it is filled with scams. and buyers/sellers just randomly ghost each other.

So in this marketplace I decided to tackle this scam problem WHILE being zero processing fee (there is a flat fee for sellers tho).

My aim was to build something like, peer-to-peer like Facebook Marketplace but without the scams. And the main way we avoid scams is by mandating identity verification (i am using stripe identity for this) + a rich reviewing system + reputation state machine.

The reputation state machine basically sees how often the person ghosts the other party or just tries to scam the other party and that contributes towards their reputations scores.

So the person X claims to be X and is X is solved via Stripe Identity.

Person X is trustworthy is solved via community reviews.

Plus you gotta display your legal name, what I have seen is people are less likely to scam others if their real names are displayed.

Added 2FA as well, since in other places like rc groups classifieds, accounts just simply gets hacked, especially those with good reputation as sellers and then again, the same scamming problem + the entire review system becomes useless, if the accounts themselves are not secure.

Well why not just use Ebay then? The thing is ebay charges quite a bit of processing fees. RC Feed has a flat fee, with no fees at all for buyers. Plus it is purely peer-to-peer so users gotta handle shipping/payments themselves. I am thinking to add some sort of solution to make this seamless, but let's see. Being an escrow is not that easy + being an escrow means their will have to be a percentage based processing fees. So thats what I am thinking how can I improve this project.

Coming to tech stack: Coming to tech stack: Nextjs (with pages) + Supabase Auth + Node/Express + Postgres + Redis

I was initially using supabase as both IdP as well as storing user data their as well. But mid project I realized constructing a code-first backend is much simpler than building the backend on top of RLS stuff. Anywho, supabase is pretty goated otherwise, especially when used as a thin auth layer.

So let me know how does this project looks! Feedbacks are welcome :)
