What is this?
Crypto buried in the ground.
Seriously.
Not QR codes on posters. No digging required. Real coins, encrypted into GPS coordinates. Your phone is the metal detector.
How it works
Discover
A mystery marker pops up on your map. Something's nearby. You don't know what, and you don't know exactly where.
Hunt
Start walking. Your phone scans the ground tile by tile. The grid turns green behind you. Keep moving.
Claim
Found it. The coin lights up. Tap claim, and it's sent straight to your account. No middleman. Yours.
Zero-knowledge
You prove you were there.
Nobody learns where "there" is.
Your claim is verified with cryptographic math, not GPS logs. We can confirm you found the coin without ever seeing your location. Not us, not other players, not the blockchain.
Nothing leaves your device except the proof.

Business cashback
Pay only when a customer walks in.
Coin World rewards real visits, not clicks. Place a drop at your storefront, customers redeem on the spot with a code from staff. If no one comes, you pay nothing.
How it works →
Run a campaign
Put your coin where your community is.
Airdrops sit in wallets and get dumped. Coin World drops get people off the couch. Someone had to walk across town to find yours. They'll remember that.
Campaign Dashboard
Drop coins on a map, set the difficulty, watch claims roll in.
Non-custodial
Your wallet to theirs. We never touch the funds.
Bot-proof
Memory-hard crypto and physical presence proofs. You can't fake a walk.
New faces
Drop coins in busy areas. People who've never heard of your project pick them up and become holders.
There's money out there.
Go get it.
