Hey Hunters! I wanted to share a quick milestone we just pushed live on Uppale.com, our community-driven visibility platform for local businesses. We just shipped a full vertical slice implementation of Two-Factor Authentication (TOTP) to protect our users' slots and account security. The most interesting part of this update is the architectural approach we chose, which was guided by two core principles: 100% privacy and zero infrastructure costs. Here is how it works under the hood: Adaptive / Risk-Based Auth: We hate tedious logins. Users are only challenged for a 6-digit security code if they log in from an unfamiliar device or location. Known devices rely on a secure httpOnly trust cookie to skip the prompt. Purely Cryptographic ($0 API Costs): Instead of using expensive SMS gateways that drain resources, we implemented a custom TOTP engine (otplib + Prisma). Secrets are stored AES-256-GCM encrypted in our Postgres DB, alongside HMAC-hashed, single-use recovery codes. Next.js 16 Stack: The feature is fully built on Next.js 16 (App Router) and React 18. It utilizes temporary session IDs stashed in Redis during the 2FA challenge window to completely withhold Supabase auth tokens until the user is verified. We wanted a production-ready system that is robust, accessible, and lightweight without paying a single cent for third-party API networks on every login, and 10/10 end-to-end tests are officially passing live on production.

Hey everyone, I just pushed a major update to Uppale, and we are officially live on Product Hunt right now! The whole philosophy behind Uppale is visibility powered by people. If users are the ones driving the platform s growth by bringing in their network, it makes no sense to just give them a pat on the back. They should actively participate in the ecosystem's economy. That s why I just rolled out our new Referral Program. I wanted to build a double-sided incentive structure that actually rewards real action. The moment a friend signs up using your personal link, you both get instant marketplace credit to boost your visibility. Then, once your referred friend completes their onboarding and starts making organic earnings on the platform, an extra bonus triggers for you because you brought a real, active contributor to the network. I spent a lot of time dialing in the UX for this. There s a clean, dedicated dashboard under your account to track your network live, with one-click native sharing covering everything from quick link copying to Facebook, LinkedIn, X, WhatsApp, Telegram, and Reddit. It s also fully integrated into the newly upgraded, lightning-fast leaderboard layout we just deployed. We are competing for the top spots on Product Hunt today, and if you love independent engineering, building in public, or just want to see how an attention market actually works, I d really appreciate your support and upvote.
