6 Crypto Principles Behind EXTRA SAFE’s Private Communication

When we think of crypto, the first things that usually come to mind are investments or digital money. But before crypto became associated with finance, it introduced a set of technologies that changed how privacy, identity, and trust work online.

Among the relatively small number of communication tools built this way, EXTRA SAFE Chat proudly applies crypto architecture directly to private communication.

Below are the 6 core crypto principles behind EXTRA SAFE Chat:

1. Cryptographic Keys at the Core

When you use EXTRA SAFE, the system creates a cryptographic key pair on your device. This pair is used to authenticate you, establish secure sessions, and encrypt your communication.

This is the same key-based model used in crypto systems, where control and verification are handled through cryptography rather than stored passwords or central identity records. So the access and privacy are handled directly by the device.

2. Ephemeral Browser Meetings

When you start a meeting from the browser, EXTRA SAFE creates a temporary Ethereum-style cryptographic account for the session. This account is used to set up encrypted voice, video, screen sharing, and in-meeting chat.

Each session on EXTRA SAFE Browser Lite runs without creating a persistent account. The session exists only for the lifetime of the meeting, and all session data is deleted when it ends.

3. Anonymous In-App Identity

In the mobile app, you get an EXTRA SAFE number that you can use as your in-app identity. This 9-digit number is linked to your cryptographic setup and can be shared with others to enable call and message reception.

While many communication apps rely on email addresses, phone numbers, or social profiles to identify users, EXTRA SAFE keeps your account separate from your real-world identity.

4. Crypto-Native Recovery

EXTRA SAFE mobile app uses the same approach as crypto wallets: a recovery phrase to restore access to your account.

When you first open the app, you receive a 12-word phrase that encodes the cryptographic data behind your setup. When entered on a new device, it recreates the same configuration and brings your account back.

This gives you a direct way to move your account between devices while keeping control in your hands.

5. Crypto-Grade Encryption

Encryption sits at the core of EXTRA SAFE Chat. Whether you send messages, files, images, or voice messages, everything is end-to-end encrypted. This encryption model is applied consistently across all communication types, using the same cryptographic approach that underpins modern crypto systems.

The content is encrypted on the sender’s device and decrypted only on the recipient’s side, keeping your data protected throughout the entire exchange.

6. Peer-to-Peer Communication

EXTRA SAFE Chat uses a true peer-to-peer model for real-time communication, following the same principle that crypto systems use for direct interaction between participants.

Voice and video streams, as well as screen sharing, travel between participants’ devices using WebRTC. This keeps real-time communication direct between participants, without a central system sitting in the middle of the exchange.
