DEV.to Submission - Postmark Challenge: Inbox Innovators

What I Built

We created an application called Identizy.

The goal is to leverage Postmark's inbound email parsing to automatically process hiring communications, extract structured KYC-like information from candidates and companies, and create identity attestations. This can help prevent hiring scams and establish trust between job seekers and recruiters.

Key features:

✅ Postmark inbound email parsing webhook
✅ Automatic data extraction into Supabase DB
✅ Public Attestation View for jurors
✅ Smart contracts deployed (ERC721 mint open)
✅ Next.js frontend for browsing attestations

Demo

Deployment Instructions (Juror Mode)

Requirements:

Node.js (>=18)
pnpm installed
Supabase account (or use provided demo credentials)

Steps:

# 1️⃣ Clone the repo
 git clone https://github.com/YOUR-ORG/identity-attestation-hiring-email.git
 cd identity-attestation-hiring-email

# 2️⃣ Install frontend dependencies
 cd frontend && pnpm install

# 3️⃣ Setup .env
 cp .env.example .env
# Fill: NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY, POSTMARK_API_KEY, etc

# 4️⃣ Run frontend
 pnpm dev

Once running locally, you can simulate inbound emails via Postmark API or inspect current records via Supabase DB directly.

How I Built It

Tech Stack:

Next.js 14 (React server components)
Supabase (Database + RLS + Storage)
Postmark (Inbound Email Parsing)
Wagmi & Viem (Smart contract interaction)
Foundry (Solidity contracts and deployment)
TypeScript, Tailwind CSS, ShadCN UI

Architecture:

Postmark sends parsed inbound emails to Next.js API route.
Next.js API inserts email data into Supabase table email_attestations.
Smart contract deployed (ERC721 mint open for future extensions).
Frontend UI lists attestations and shows candidate/company verification states.

Why this use case?

Many hiring scams today happen via email.
Bringing identity attestations to hiring conversations adds trust & verification layers.
Email-based onboarding allows gradual KYC-like attestations without centralized gatekeepers.
