True randomness, From hardware.
The world's first offline Seed Phrase generator. ELLIPAL Joy draws yours from a true hardware random number generator, open for anyone to inspect.
Random. Offline. Open to check.
A Seed Phrase is only as safe as the randomness behind it, and you should be able to see exactly how yours is made.
Random by Physics
From the chip's analog noise, not software.
Offline by Design
No WiFi, no Bluetooth, no connection.
Open Source
Inspect how every phrase is made on GitHub.
Randomness is the root of security.
Your Seed Phrase is the master key to your crypto. If its randomness can be predicted, so can everything built on it. ELLIPAL Joy draws yours from real hardware noise in the ST chip, so it stays unpredictable and known only to you.
Don't trust. Verify.
ELLIPAL Joy's code is fully open source. Anyone can inspect how each phrase is made and verify it on GitHub. Do not take our word for it, check it yourself.
One standard. Every wallet.
ELLIPAL Joy makes a standard BIP39 phrase, 12, 15, 18, 21, or 24 words. Import it into nearly any wallet, so your recovery never depends on one device.
Four steps, fully offline.
Power it on and generate. No app, no account, no connection.
Common questions, straight answers.
True hardware randomness, generated offline and known only to you.
Worried about hacking?
Complete network isolation: no WiFi, Bluetooth, or connections.
Is it truly random?
Yes. The chip draws randomness from physical analog noise, not predictable software.
Could it be pre-loaded?
No, and you do not have to take our word for it. The code is fully open source, so anyone can audit exactly what it does on GitHub.
Works with other wallets?
Compatible with any wallet that supports the BIP39 standard, hardware or software.
