Three ideas, made simple

Private by default

Sender, receiver, and amount are hidden at the protocol level.

Post-quantum design

Built on hash-based cryptography for long-term post-quantum security.

Private smart contracts

Programmable transaction logic can execute without exposing the data behind it.

The privacy problem

Public money leaves a trail. Neptune Cash does not.

Digital payments often create lasting records. Neptune brings cash-like privacy online so everyday transactions do not become a public profile.

Why privacy matters Compare with Monero and Zcash

Public chain

Transparent and publicly visible
