EXTRA SAFE: Self-Custody Chat

EXTRA SAFE

About this app

EXTRA SAFE is a self-custodial messenger with a built-in stablecoin-first wallet, the chat layer for transferring tokenized dollars and other assets. Send USD₮, USDC, and other stablecoins to a contact as naturally as sending a message, and pay gas in the same stablecoin. Pick a name, get your EXTRA SAFE number, and you're set up in seconds. No SIM is required to get started.

WHAT YOU GET

1. Stablecoins in chat
Send USD₮, USDC, and other assets to a contact in chat, straight from the attachment menu, wallet-to-wallet. The transfer confirms in seconds. A name or EXTRA SAFE number is all you need; the app handles addressing and routing.

2. See who you're paying
Call a contact first, video or audio, from the same chat to confirm you're paying the right person, then send stablecoins without leaving the conversation or switching apps.

3. Gas settles in the stablecoin you send
You don't have to buy a native coin to send tokenized dollars. The fee comes from the same stablecoin you're sending. It's part of UGTP (Universal Gateway Transaction Platform), running under every in-app transaction: you choose the outcome, and it builds the transaction to deliver it.

4. Transparent fees
Every transfer shows its full cost before you confirm.

5. Self-custodial, stablecoin-first wallet
Your keys are generated on your device and stay there. You own your funds – no one can freeze them. Send across six leading EVM networks: Avalanche (default), BNB Chain, Ethereum, Polygon, Base, and Arbitrum. The recipient gets the asset you selected. The on-chain layer stays invisible.
Send stablecoins and other assets to contacts in chat or to any external self-custodial wallets or centralized exchanges from the Wallet tab.

6. Private balances & transfer amounts
Keep the amount you're sending hidden; the transfer itself stays visible. Convert stablecoins and AVAX into a private balance, send it in the app, and reveal the amount only when you choose. Private balances and transfer amounts use the eERC standard by Avalanche.

7. End-to-end encrypted chats
Every message, file, image, and voice note is end-to-end encrypted: keys live on your device, and your contact decrypts content only on their device. EXTRA SAFE's servers carry messages only in encrypted form. Every chat runs on your timer: once your contact views the content, it clears after the time you set, from one minute to one month.

8. Gift links
Gift stablecoins to your closest people with a funded link: stablecoins already inside, and a wallet created the moment your contact opens it. Usable from day one.

9. Device-to-device calls
Calls connect directly between devices, peer-to-peer. In-call chat is encrypted and clears when the call ends. Group calls support up to 5 people.

10. One identity
One name, one EXTRA SAFE number for messages, calls, and assets. Pick a name and start: your identity is created in the app, independent of email, phone number, or SIM. One 12-word recovery phrase restores your account and wallet on any device.
Your chats, contacts, and assets stay yours fully.

11. Encrypted backup
Save a password-protected backup of your recovery phrase to Google Drive or iCloud so losing your device doesn't mean losing your account.

Ratings and reviews

ExtraSafe is an amazing privacy-focused app! No phone number or email required to create an account, just a simple wallet-like setup. It also comes with an inbuilt crypto wallet, making it even more convenient. If you value privacy and simplicity, ExtraSafe is definitely worth trying!

Will have to find a better alternative. Cannot use for only line of contact when the app will not work unless it's updated. This is unacceptable and needless.

Hi Extra Safe Team Your app is hanging a lot. Your app is not running smoothly at all. Update your app to improve performance, otherwise your app will become useless. It hangs every time you open it.

What’s new

EXTRA SAFE is updated: a built-in EXTRA WALLET is live. One address enables three accounts — public, smart, and private. Gas settles in the same stablecoin you send. Private Tokens on Avalanche protect your balance and the amount you send. Send to a contact in chat, or to any external wallet. Gift links with password protection. Link previews, image zoom, uploads up to 50 MB, share-to-chat from any app. Plus dozens of fixes across send, receive, and deposit flows.
