your privacy platform

Arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say.

Mission Statement

The Shadow Project's mission is to develop free and open source software that securely enables anyone in the world to exercise their natural human rights to privacy, communication, and commerce.

All-In-One Solution

UMBRA is the ideal application for anyone seeking online privacy & security for financial transactions, communication, or shopping. Umbra's users include programmers, businessmen, and other creative minds--like journalists and whistle-blowers--in need of a secure place to gather, discuss, and exchange information. UMBRA's users also include people wanting to directly exchange goods and services without third parties, exorbitant fees, and other risks associated with centralized commercial platforms.

Encrypted messaging

Our secure messaging operates through a decentralized network. Anyone can send and receive messages without revealing a drop of metadata. Most messengers have one flaw in common: they expose your IP address to centralized servers. In our system every node relays every message to their peers removing the IP address from it such that the sender nor receiver can be identified. Extra layers of protection such as Tor and I2P can be applied to hide your presence on the network itself.


Organize your team conversations in open channels. Make a channel for a project, a topic or a team. Everyone has a transparent view of all that’s going on.

Private Channels

For sensitive information, create private channels and invite a few team members. No one else can see or join your private channels.

Direct messages

To reach someone directly, send them a Direct Message. It's completely private and secure.

Private E-Cash System

UMBRA uses ShadowCash as its underlying currency. It goes beyond other digital currencies to make transactions invisible to the public eye, but still nearly seamless for users, who can conduct their business privately anywhere in the world.

ShadowCash makes use of dual-key stealth address and ring signatures enabling secure anonymous transactions. The blockchain reaches consensus by a Proof-of-Stake protocol, currencyholders earn an annual 2% income on their SDC holdings when staking.

Decentralized Marketplace

While still under development, UMBRA's decentralized marketplace has already received major news coverage from several well known media outlets. Upon its public release, the ShadowMarket will be the first of its kind: an inter-dependent, decentralized ecosystem that will revolutionize the way people privately & securely purchase goods and services online.



Some bounties for projects around ShadowProject will be available soon. Stay tuned!
