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.

PRESS KIT // 2026

Z-TEXT — zk-SNARKs blockchain messenger

This press kit contains our own weaknesses. That's what makes it usable.

Z-TEXT is a zk-SNARKs blockchain messenger built on BitcoinZ — no phone, no email, no SIM, zero metadata. Below is everything a journalist needs to write a real story: verified facts, an interactive tool that scores us honestly (including where we lose), pre-approved quotes, and direct contact — no PR firm in between.

Status: Public beta live — licenses, wallet, and messaging are already running at z-text.com. Broader app store rollout is underway across multiple stores. This is early access, not a hypothetical.

§01

Try to catch us lying

Rank what matters to you. We'll show exactly where Z-TEXT lands among 29 messengers — scored on the same 8 criteria as everyone else, no matter what you pick. It rarely wins. That's the honest result of a scoreboard we built the same way for all 29 apps, including our own.

1st priority (matters most) 2nd priority 3rd priority

Known limitations — published in full at z-text.com/docs/security

No group calling yet. No independent third-party security audit yet — built on audited Zcash cryptography, but Z-TEXT's own implementation hasn't been externally audited. A timestamp-based nonce in one non-critical component and an unprotected panic-PIN toggle at file level are known issues; neither affects funds or message confidentiality.

§02

Boilerplate

Copy-paste ready. No need to email us for a usable paragraph.

Z-TEXT is a zk-SNARKs blockchain messenger built on the BitcoinZ network. It requires no phone number, no email, and no SIM card, and collects zero metadata by design. The app combines a shielded messenger, a password manager, a non-custodial crypto wallet, and Channels broadcasting under a single 24-word recovery seed. Z-TEXT LLC is self-funded, based in Wyoming, and publishes its own threat model and known security limitations publicly rather than only its strengths.

§03

Story angles

Four ready hooks, ranked by how unusual they are — not how flattering.

The messenger that scored itself honestly, and shipped it anyway

Z-TEXT built an open comparison tool against 28 other messengers, on 8 criteria, and lands 27th of 29 overall — a rare case of a company publishing a scoreboard it doesn't win.

Self-funded, no VC, two people

No investor board, no venture round. The founder and one remote developer built the app, the blockchain integration, and the infrastructure independently.

What happens when your messenger's company disappears

Wickr (Amazon) shut down in Dec 2023. Skype (Microsoft, once an $8.5B acquisition) shut down in May 2025. Both apps now score zero on every criterion — not from broken encryption, but because a company decided to stop running servers. Z-TEXT's identity is a recovery seed, not a company account.

Governments are already moving to blockchain

Wyoming — where Z-TEXT LLC is incorporated — became the first U.S. state to issue its own blockchain-based digital currency (Frontier Stable Token, live since Jan 2026). The Bank of Japan is expanding its own blockchain settlement infrastructure in 2026. What most of those systems don't add is a privacy layer — which is where zk-SNARKs comes in.

§04

Pre-approved quotes

"We scored our own app honestly against 28 others, using the same rules for all of them. It loses on group calling and network size — because it's new, and those are real weaknesses. Publishing that felt riskier than hiding it. It wasn't."

— Eric Pierrot, Founder, Z-TEXT LLC

"A messenger built on a company's servers only exists as long as that company keeps paying for them. Wickr and Skype prove that. Z-TEXT's identity is a 24-word phrase, not an account — no company can shut that off."

— Eric Pierrot, Founder, Z-TEXT LLC

Live proof, not a screenshot

A screenshot can be cropped or staged. The blockchain can't. Open the real BitcoinZ explorer and look at any shielded transaction yourself — sender, receiver, and content are not visible, on any transaction, to anyone, including us.

explorer.btcz.rocks → — search any transaction hash. Shielded fields show as encrypted, not blank or redacted — there was never plaintext to hide.
