EXTRA SAFE vs Pena.

EXTRA SAFE is a self-custodial messenger with a built-in stablecoin-first wallet — the chat layer for transferring digital assets. Send USD₮, USDC, and other tokens to a contact the same way you'd share a photo, and pay gas in the same stablecoin you send. Pick a name, get your EXTRA SAFE number, and you're set up in seconds. WHAT YOU GET 1. Stablecoins in chat Send USD₮, USDC, and other tokens to a contact in a chat, straight from the attachment menu, wallet-to-wallet. The transfer confirms in seconds. A name or an EXTRA SAFE number is all you need — the app handles addressing and routing underneath. 2. Gas settles in the stablecoin you send You don't have to buy a native coin to send tokenized dollars. The fee comes out of the same stablecoin you're already sending. It's part of UGTP — an intent-based platform running underneath every in-app transaction: you set the outcome, and the platform builds the transaction that delivers it. 3. Self-custodial, stablecoin-first wallet Your keys are generated on your device and stay there. Send across six leading EVM networks — Avalanche (default), Ethereum, Polygon, BNB Chain, Base, and Arbitrum — and the recipient gets the token you selected. The on-chain layer stays invisible. You can send EXTRA SAFE tokens to contacts in chat, or to any external self-custodial wallets or centralized exchanges, from the Wallet tab. 4. Private Tokens Keep the amount you're sending hidden — the transfer itself stays visible. Convert any asset you hold into a Private Token, send it right in the app, and reveal the balance only when you choose. Built on eERC, Avalanche's encrypted token standard, live on Avalanche. 5. Zero-knowledge encrypted chats Every message, file, image, and voice note is end-to-end encrypted: keys live on your device, and content is decrypted only on your contact's device. The architecture makes it structurally impossible for us to read your messages. 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. 6. Gift links Bring your closest people into stablecoin payments with a funded link: stablecoins already inside, a wallet created the moment your contact opens it. Usable from day one. 7. 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 with up to 5 people are free and unlimited. 8. 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 itself, 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 fully yours.
