Private by default
Sender, receiver, and amount are hidden automatically: no opt-in required.
- Prevents balance tracking and transaction profiling
- Protects against scammers, advertisers, and chain surveillance
- Your financial activity stays yours
Why Neptune Cash
On most blockchains, every payment you make and every balance you hold is public, forever. Neptune Cash is a privacy-first cryptocurrency built so that neither has to be. Here's what makes it different.
Built to be programmable
Neptune combines private payments with smart contracts via Triton VM.
- Conditional payments and automated settlement
- Private financial agreements without data exposure
- Applications beyond simple send and receive
Post-quantum from day one
Security is built on quantum-resistant hash functions: no migration needed later.
- Spending authority rests on hash-based cryptography, not elliptic curves
- Designed for a post-quantum world from the first commit
- No risky community-wide migration required later
Lightweight chain verification
In developmentzk-STARKs and recursive proofs are designed to make syncing fast and lightweight.
- Will verify the chain in seconds, not hours or days
- No need to replay years of blockchain history
- Scales on layer 1 without trusted third parties
Community-driven
A 1.98% premine funded 4 years of original development. The rest is mined.
- No institutional or venture capital (VC) control
- No coordinated token dumps by early backers
- New supply via competitive proof-of-work only
