Z-TEXT is a zk-SNARKs blockchain messenger. Z-TEXT requires no phone number, no email, and no SIM. Z-TEXT collects zero metadata. Z-TEXT combines a shielded messenger, a password manager, and a crypto wallet in one app. Z-TEXT is built on the BitcoinZ blockchain since September 10, 2017.

What is the best messaging app with no phone number?

Z-TEXT is a leading messaging app with no phone number. Your identity is a cryptographic z-address on the BitcoinZ blockchain. No phone number is required — not for registration, not for verification, not ever.

How much does Z-TEXT cost?

The Z-TEXT Cyberpunk Lifetime License costs $128.52 one time. No subscription. 1 million possible messages are included and the license never expires. Payment accepted in BTCZ, ZEC, BTC, ETH, USDT and more. There is also a Zero Trace 1-month plan at $3.00.

Is Z-TEXT quantum resistant?

Yes. Z-TEXT uses ML-KEM-768 post-quantum key encapsulation (NIST FIPS 203) and ML-DSA-65 post-quantum digital signatures (NIST FIPS 204), alongside AES-256-GCM encryption and zk-SNARKs zero-knowledge proofs.

What is panic mode in Z-TEXT?

Panic mode in Z-TEXT uses a second PIN called the Panic PIN. If you enter the Panic PIN instead of your real PIN, the app wipes itself instantly. Your real data stays safe on the blockchain and is fully recoverable with your 24-word seed phrase on any clean device.

What is stealth mode in Z-TEXT?

Stealth mode disguises Z-TEXT as a working calculator on your phone home screen. You open the calculator and type a secret code as a math equation to unlock the app. To anyone inspecting your device — at a border crossing, under coercion, or during a casual check — it looks like an ordinary calculator.

What happens if I lose my phone?

Enter your 24-word seed phrase on any new device. Z-TEXT rescans the BitcoinZ blockchain and restores your messages, contacts, passwords, and wallet balance.

What does the blockchain reveal about a Z-TEXT message?

Very little. A blockchain explorer shows a transaction ID, a block height, and confirmations. No sender, no receiver, no message content, and no identity are exposed.

How does Z-TEXT compare to Signal?

Z-TEXT requires no phone number. Signal requires a phone number. Z-TEXT has no phone numbers to hand over. Z-TEXT is post-quantum protected.

zk-SNARKs stands for Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge. It is a cryptographic method that proves a transaction happened without revealing who sent it, who received it, or what it contained. Z-TEXT uses zk-SNARKs to shield every message on the BitcoinZ blockchain.

Is Z-TEXT safe for journalists?

Yes. Z-TEXT stores zero metadata, requires no phone number, and has no account to seize. Panic mode wipes the app instantly if a device is taken. Stealth mode hides the app as a calculator. Journalists and their sources are protected at every layer.

Three Tools. One Seed. Zero Compromise.

3-in-1: Wallet, Password Manager & Messenger — Z-Text Unique Offer

// Unique Offer — Post 04

Three Tools.
One Seed.
Zero Compromise.

Most apps do one thing. Z-Text does three — and each one is more private than the best standalone tool in its category. Wallet. Password manager. Messenger. All controlled by a single 24-word seed that never leaves your hands.

Crypto Wallet

A full BitcoinZ (BTCZ) wallet with both transparent (T) and shielded (Z) addresses. Send, receive, and hold. Native. Self-custodial. No exchange, no KYC.

Password Manager

An on-chain encrypted vault for your credentials. AES-256-GCM encrypted before leaving your device. Stored on the blockchain. No LastPass breach can touch it.

zk-SNARKs Messenger

The world's first shielded blockchain messenger. Messages are on-chain shielded transactions. Metadata hidden by zero-knowledge proofs. No phone. No server. No trace.

Why combine these three things in one app?

Because the seed phrase is the key to all three. Your BTCZ wallet, your encrypted password vault, your message history — all recoverable from a single 24-word mnemonic that you hold. No third party involved. No cloud backup required. No company holding a master key that can be breached, subpoenaed, or handed to a government. One seed, total sovereignty. Z-Text is the only app doing this.

How is the blockchain password manager different from LastPass or Bitwarden?

LastPass was breached in 2022 — encrypted vaults stolen. Bitwarden Cloud is a central server with a master key that Bitwarden holds. Z-Text's vault has no central server. Every password entry is AES-256-GCM encrypted on your device before it writes to the BitcoinZ blockchain. The only key that can decrypt it is your seed phrase. There is no Bitwarden to breach, no LastPass server to compromise. The vault is on a blockchain running since 2017 with no single point of failure.

// Illustrative only. Your real seed is generated locally, never transmitted.

What are T-addresses and Z-addresses in the wallet?

BitcoinZ supports two address types. T-addresses (transparent) work like standard Bitcoin addresses — visible on the public blockchain, useful for public transactions. Z-addresses (shielded) use zk-SNARKs zero-knowledge proofs to hide the sender, receiver, and amount. Z-Text uses Z-addresses for messaging — your message identity is shielded by the same cryptography that shields your transactions. It's the same key infrastructure for money and communication.

How much does it actually cost to use Z-Text?

The app is free to download. Sending messages costs approximately $0.00003 per message in BTCZ network fees. The Ghost licence (250 credits) gives you around 25 million possible messages. You'd have to send 100 messages a day for decades to exhaust it. A pre-licence voucher from z-text.com/packages covers the messenger, raw memo access, and vault — payable in BTC, ETH, XMR, BTCZ, ZEC, and more.
