Seal your words on the blockchain. Forever.
Every app you've used can delete your words, ban you, get hacked, or get shut down. zketernity works differently — permanently inscribe a short message onto the BitcoinZ blockchain. No account. No app. Just proof it existed.
👉 Seal Your First Message🐘 Hard Mode $1
Your thought, directly on-chain. Permanent. You get the transaction hash — undeniable proof.
🐘 Easy Mode $3
Same permanent inscription, plus a QR code and shareable certificate — built for memories.
🔒 Eternal+ $5
Your message is encrypted before it's sealed. Only you hold the key to unlock it — today, next year, or never.
How it works

Write your message — up to 400 characters.
2
Pick $1, $3, or $5 and tick "Private message."
3
