The problem Specter solves
Your POAP Is a Surveillance Report
Every badge you claim permanently links your wallet → your body → a location → a date.
On a public blockchain. Searchable by anyone. Forever.
Who's Reading It Right Now
Your boss sees you claimed a POAP at a competitor's conference — on your sick day.
A stalker sees you attend the same conference every year, alone, in the same city.
Your government sees you at a protest, a political event, a "wrong" gathering.
A recruiter sees you at a job fair. Your current employer finds out.
A data broker aggregates 50 POAPs into a complete behavioral profile and sells it.
You didn't post anything. You just wanted the badge.
The Brutal Math
1 POAP = 1 data point
10 POAPs = a travel pattern
50 POAPs = your complete location history,
political profile, social graph —
all public, all permanent,
all searchable for free
Unlike a tweet — you cannot delete it.
The Solution
Specter — One Swap. Total Privacy.
Before: poap.xyz/mint/x3izg6 → your public wallet
After: specter.xyz/mint/x3izg6 → a ghost address
nobody can link to you
Same link. Same POAP. Zero trace.
How It Works
| Step | What Happens |
|---|---|
| 👆 Tap your fingerprint | Passkey derives your stealth keys — never stored, never uploaded |
| 🔮 Ghost address computed | A fresh address that has never existed on-chain before |
| 🏦 BitGo mints the POAP | Treasury wallet sends the badge to your ghost address |
| 📣 Announcement published | Only you — with your viewing key — can find it |
| ✅ Done | On-chain: a random wallet got an NFT. You: untraceable. |
The Guarantee
- ✦ Your ENS never touches the transaction
- ✦ Your wallet never appears on-chain
- ✦ The stealth address never existed before this moment
- ✦ Your private key was never stored anywhere
- ✦ The POAP is 100% yours — prove attendance to anyone, on your terms
You were there.
The chain wasn't watching.
