EXTRA SAFE: Self-Custody Chat

EXTRA SAFE is the first messenger built on money rails, where chat and crypto work together under one identity. Get started in seconds: just pick a name, and you are set up instantly.
A built-in non-custodial wallet and encrypted chat live in one app:
Send digital dollars (USDT) and Ethereum inside any conversation, the same way you'd share a photo.
Manage your crypto in the Wallet tab.
Receive funds with your EXTRA SAFE number.
The crypto layer is fully there – on-chain and self-custodial – but stays in the background. Your number handles addressing, routing, and the rest. In EXTRA SAFE, you create a single identity for your conversations and crypto.
The app is designed so anyone can move digital money, whether they've done it a hundred times or never. EXTRA SAFE offers a unique, smooth experience: chat on the surface, crypto in the background.
WHAT YOU GET
1. In-chat crypto/stablecoin transfers
Send crypto and digital dollars directly to a contact from the attachment menu, wallet-to-wallet. ETH and USDT land instantly, just like a photo. Support for more coins and tokens is planned soon, so you can look forward to more asset options.
2. Encrypted chats
Every message, file, image, and voice note is end-to-end encrypted – keys generated on your device, decrypted only on your contact's device. Set a timer, and everything disappears once seen, from one minute to one month. Nothing is stored permanently.
3. Built-in non-custodial wallet
The Wallet tab sets up in seconds. Your private keys are generated locally and stay on your device. If you lose your device, you can restore your wallet and account by entering your 12-word recovery phrase on a new device. Send, receive, and manage ETH and USDT without leaving the app.
4. Device-to-device calls
Calls go directly device-to-device by default, keeping routing servers out of the picture. In-call chat is encrypted and disappears when the call ends. Group calls with up to 5 people are free and unlimited.
5. One identity for everything
Pick a name, and you're in. One identity for messages, calls, and crypto. One 12-word recovery phrase restores your account and wallet on any device.
The new money is already here. EXTRA SAFE is the place where you actually use it.
