Startup seeking a full-stack dev to help us create a basic crypto "Proof Of Funds" PDF generator

Fixed rate for MVP: $5,000 USD

Ever tried to rent an apartment and the landlord doesn't really trust your crypto portfolio lol?


We're building the solution to that:


  • Simple web app that lets crypto holders connect all of their wallets
  • Shows how much money they have in their crypto wallets, and generates an official "proof of funds" PDF and QR code that landlords, real estate agents, loan companies etc can scan and verify
  • Helps people prove their financial status (for rentals, loans, etc.)

What You'll Do

  • Create a website where users can:
    1. Connect their crypto wallet
    2. See their total crypto balance
    3. Generate a clean, official-looking PDF
    4. Optional: Verify identity with a quick ID check, using 3rd party KYC like Persona, etc

Technical Stuff We Need


  • Use React/Next.js
  • Connect to crypto wallets
  • Pull wallet balance from blockchain
  • Create nice-looking PDFs
  • Set up payments via Stripe
  • Make it look professional

Tech needed:

  • Next.js
  • Stripe for payments
  • WalletConnect to link wallets
  • Persona for KYC (optional)
  • PDF generation library

Project Details

  • 2-3 weeks max to build
  • Straightforward utility tool
  • Clean, simple design
  • Budget approx $5,000 USD

Perfect for a Developer Who:


  • Loves building practical tools
  • Understands crypto basics, yet still has a modern SAAS design sense
  • Can make something look professional
  • Wants a quick, interesting project
