How It Works · Z-Text Messenger # From Install to Invisible Message 5 steps to true private communication — no phone number, no server, no trace 1 Setup · 2 minutes ### 🔐 Install & Create Your Wallet Download Z-Text free on Android or iOS. Create a wallet — you get a **24-word seed phrase**. That's your identity, your keys, and your backup. Write it down, store it safely. No email. No phone number. No registration form. Identity = cryptographic z-address (zs1...) · No SIM card · No carrier record 2 Fund · Optional micropayment ### 💰 Add a Tiny Amount of BTCZ To send messages and use the password manager, you need a small amount of [BitcoinZ (BTCZ)](https://getbtcz.com/?ref=z-text.org) to cover on-chain fees. We're talking fractions of a cent per message — the protocol charges this to prevent spam automatically. \~$0.00003 per message · Economic spam barrier · No moderators needed 3 Connect · No phone number exchange ### 🤝 Add a Contact via Z-Address Share your z-address with someone — that's your private messaging handle. They add you, you add them. A mutual cryptographic handshake is established. No phone book access required. No central directory. Nobody else can even see that you two are connected. z-address starts with "zs1" · Mutual handshake before any message flows · Private by design 4 Send · Local encryption first ### ✍️ Write & Encrypt Locally Type your message. Before anything leaves your device, Z-Text encrypts it using **AES-256-GCM** right on your phone. The plaintext never touches the internet. What gets broadcast is pure ciphertext — unreadable to anyone except the recipient. AES-256-GCM local encryption → zk-SNARKs shielded transaction → BitcoinZ blockchain 5 Deliver · 1–5 seconds ### 📡 Broadcast as a Shielded Transaction The encrypted message is sent as a **shielded transaction** on the BitcoinZ blockchain. The recipient's app picks it up via G-stream mempool push in 1–5 seconds. The message then permanently settles on-chain. Recoverable forever — just restore your seed phrase on any device. zk-SNARKs hide sender + receiver + amount · No server to seize · No central point of failure 3-in-1 App Z-Text is three essential tools built into a single seed phrase 🔐 A #### Crypto Wallet T + Z shielded addresses. Send, receive & hold BTCZ. Your keys, your coins — always. 🗄️ B #### Password Manager On-chain encrypted vault. No cloud. No breach possible. Restored with 24 words. 💬 C #### Private Messenger zk-SNARKs encrypted text. No phone number. No server. No IP exposed. ### Get Access Before Launch Pre-licence vouchers are available now.
