Z-TEXT
Launched this week
Private messenger with no phone number, no email, no SIM.
New: Shielded Permanence™. Messages live permanently on the BitcoinZ blockchain and stay unreadable thanks to zk-SNARKs. The proof a message exists is public. Everything else is invisible.
One 24-word seed runs 5 tools: messenger, BTCZ wallet, password manager, Channels and disposable identities.
Stealth mode hides the app behind a calculator. Quantum-resistant key exchange (ML-KEM-768). Android, macOS, Windows, Linux.

Hi Product Hunt, I'm Eric, founder of Z-TEXT.
I believe in zk-SNARKs the way some people believe in free speech. A journalist or a whistleblower shouldn't have to trust a company. The math should protect them, not a privacy policy.
So I built a messenger that never asks for a phone number. Your identity is 24 words.
What's new: Shielded Permanence™. Your messages can't be erased, and no one but the recipient can read them. Not even us. Honest limits: • Text only, no photos or voice. •
The app isn't independently audited yet.
There's a public bug bounty and a published threat model.
• iOS is coming to the App Store. Ask me the hard questions. I'll answer every comment today.
Why pay?
The wallet and reading messages are free, forever.
Sending needs a license, from $3 a month. We're self-funded with no ads, so you pay with money, not with your data.
Your metadata stays hidden
What if authorities ask Z-TEXT for my messages?
Z-TEXT LLC follows the law.
But we don't hold your messages, your contacts or your keys.
zk-SNARKs mean we can't disclose what we don't know.
Disposable identities?
A fast track inside the app.
Create a new shielded identity, message, then wipe it.
No seed backup step, so it's quick.
The flip side: once wiped, that identity is gone for good. That's the point.
LAUNCH · MONDAY, OCTOBER 5, 2026
Shielded Permanence™ is coming alive!
"Just another messenger?" NO.
Z-TEXT is a wallet-native, censorship-resistant communication layer, where:
• Your audience lives in your wallet
• Your identity is your seed phrase
• Your messages are shielded on-chain
• Your metadata stays hidden
• Your key exchange is quantum-resistant
A fundamentally different model from Signal, Telegram, or any centralized platform.
