About ARX: Private Messenger

Private encrypted messenger with a Web3 wallet, card, vault and global eSIM

ARX: the private messenger that carries your whole digital life

ARX is a privacy-first messenger with a self-custodial crypto wallet, a spendable card, global eSIM data, and an encrypted vault. One app. No phone number or email required. Nothing tracked.

Private messaging, first

End-to-end encrypted chats, voice, and video powered by the Signal Protocol. Groups, voice notes, files, and live location, private by default. Optional disappearing messages, mutual screenshot consent, and a duress code keep you in control.

Crypto in the chat

Send or request crypto right inside a conversation with a non-custodial, multi-chain wallet for Ethereum and EVM networks. Your keys, your assets. Connect to dApps with WalletConnect.

ARX Card

Spend your crypto anywhere cards are accepted. Top up from your wallet and pay in stores and online.

Global eSIM

Get online in 190+ countries with no physical SIM. Buy a data plan right inside the app.

ARX Vault

Encrypted notes, files, photos, and passwords, protected on your device and synced to your private cloud.

Privacy by design

Your account is secured by keys stored on your device, with PIN, biometrics, and duress PIN support. We do not track you and cannot read your messages.

Built-in VPN: Coming Soon

Your messages, your money, your data. In one private app.
