Generate cryptographically secure 12, 18, or 24-word seed phrases.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose 12 words (128-bit), 18 words (192-bit), or 24 words (256-bit).
Generate cryptographically secure mnemonic words using browser CSPRNG.
Write down your recovery words in order on physical backup media.
Yes. The words are selected using window.crypto.getRandomValues entirely inside your browser's local memory. No network requests are made.
