The first crypto built to leave the blockchain.The first crypto
built to leave
the blockchain.
Crypto isn't private.
It's permanently online.
On-Chain Crypto
Anyone can see your wallet, balance, and movements.
With a Phantom Key
Your crypto leaves the blockchain.
Cash is private by default. Crypto isn't.
Ghostcoin lets you take assets offline with a Phantom Key and summon them back privately using zero-knowledge proofs.
Vanish off-chain.
Summon privately.
Ghostcoin uses ZK proofs to verify ownership without revealing identity or history.
Vanish
Move crypto off-chain and receive a Phantom Key.
Phantom Key
Store it anywhere. It's private and portable.
Summon
Use ZK proofs to return crypto without a trace.
Phantom Keys offer privacy and control similar to holding cash.

Building the future of offchain crypto assets together.
The most secure form of crypto. Because it can exist off the internet.
Governments protect their most critical information by storing it offline. Ghostcoin works the same way. When you vanish your crypto, it becomes a private Phantom Key only you control — not an online balance someone can track, freeze, or seize.
Offline by choice
Your Phantom Key exists off-chain, where hacks, exploits, and network attacks can't reach it.
Physical security
Store it like any important document — a safe, a drawer, or anywhere offline. You control access, not the internet.
Untraceable return
ZK proofs prevent the chain from linking the vanish and the summon. No one can trace where the crypto came from or where it goes.

Developers

Offline is the
new on-chain.
Blockchains made money programmable — and public.
Ghostcoin adds a private offline layer where crypto is held securely and restored with zero-knowledge proofs.
No linked history and no exposed balances.
Freedom
Use your crypto without surveillance or tracking.
Privacy
Your financial activity stays yours — not public.
Control
Only you decide when and where your crypto appears.
Security
Offline storage keeps your assets safe from exploits.
Autonomy
No intermediaries. No gatekeepers. No approvals.
Peace
Know your value is stored privately and safely.
You'd never hand a stranger your bank statement.
But today's blockchains expose your entire financial history to everyone.
Ghostcoin changes that.
