End-to-end encrypted messenger with integrated payments

Encrypted messaging, voice and video with a payment rail built into the conversation.

The challenge

Privacy-focused messengers and payment apps have historically been separate products, which means the moment a conversation turns into a transaction, users leave the encrypted channel.

Building both into one app raises the stakes on the cryptography — it is now protecting money as well as messages.

Our approach
01

Encrypt everything

End-to-end encryption secures messages, calls, photos and videos across the platform.

02

Give users control of persistence

Self-destruct timers let senders decide how long a message survives on the recipient's device.

03

Encrypt the calls too

Voice and video calling run with the same encryption guarantees as messaging.

04

Build in payments

Integrated cryptocurrency lets users send and receive payments using Paybius Coin without leaving the conversation, alongside premium number purchase.
