ShadowTalk protects your privacy. A messaging experience designed for maximum security.
The Problem with Current Messengers
Even the most secure messaging apps leak metadata that can expose your entire social network
Who You Talk To
Servers know your complete contact list and communication patterns, revealing your social network even if messages are encrypted.
When You Communicate
Connection timestamps and frequency data expose your daily routines, sleep patterns, and activity levels.
Where You Are
IP addresses reveal your location every time you connect, creating a detailed map of your movements.
Your Relationships
Message frequency and timing patterns reveal close relationships, work contacts, and social hierarchies.
Why ShadowTalk is Different
Zero metadata by design. Every architectural decision prioritizes your privacy.
Zero Metadata Exposure
No servers track who you talk to, when you communicate, or where you are. Your social network stays completely private.
Dual Security Modes
Choose maximum security (Ping-Pong) for sensitive contacts or balanced mode (encrypted relays) for everyday messaging.
Blockchain Identity
Your cryptocurrency wallet is your identity. No phone numbers, no email, no personal information required.
Hardware Security
Keys stored in your phone's security chip (StrongBox/Secure Enclave). Never exposed, never compromised.
Panic Button Protection
Duress PIN instantly wipes all data and notifies contacts to delete queued messages. No evidence left behind.
Fully Decentralized
No company to compel, no servers to hack, no single point of failure. Truly peer-to-peer communication.
Text-Only Messaging
Messages are strictly text-based to prevent malware distribution, exploit vectors, and content-based abuse. Pure communication without security compromises.
One-Click Identity Reset
Instantly generate a new identity with a single click. Each identity is permanently recorded in our encrypted blockchain directory, ensuring no identity can ever be reused or revealed.
How It Works
Simple to use, sophisticated under the hood
Create Your Identity
Use your cryptocurrency wallet as your messaging identity. One key secures both your crypto and your messages. No phone number or email required.
Find Contacts
Contacts publish encrypted "contact cards" on the blockchain. Only people who know your handle can find you. No central directory exists.
Choose Security Mode
Maximum security (direct Ping-Pong) for sensitive contacts, or balanced mode (encrypted relays) for everyday messaging. You decide per contact.
Send Encrypted Messages
Messages are end-to-end encrypted and routed through Tor. No intermediary can see content, sender, recipient, or timing patterns.
