🔐 About Coinseal
Coinseal is pioneering the next evolution of crypto security. We’ve reimagined the seed phrase—long a single point of failure in wallet security—by creating a system that scrambles and protects phrases offline using a user-specific full-digit passcode. If the code is incorrect, a fake seed unscrambles, ensuring zero leak risk.
Think of us as what seed phrases did to private keys—only better.
We’re a startup with a working proof-of-concept, ready to scale. Now we’re seeking elite contributors who want to build the future of secure self-custody.
