Proof of Experience (PoX): Verifiable Event Credentials for the Web3 Era

Overview

PoX is a decentralized application that turns every event you attend into a verifiable on-chain credential — no wallet, no friction. Powered by Civic Auth, it bridges Web2 and Web3 by minting soulbound NFT tickets, syncing events to your Google Calendar, and sending proof directly to your Gmail.

---

Problem

• No verifiable credentials for attended events
• Reliance on screenshots, QR codes, or centralized emails
• Poor interoperability between Web2 tools and Web3 identity
• Lack of on-chain recognition for real-world experience
• Wallet onboarding complexity for non-crypto users

---

Solution

PoX solves this by:

• Enabling Civic Auth login (no seed phrases or MetaMask)
• Creating embedded wallets
• Minting soulbound NFT tickets
• Auto-saving events to your Google Calendar
• Emailing proof with transaction details to Gmail
• Storing a permanent on-chain experience badge
