Security

Your keys never leave your device — verified by architecture, not by promises.

🔒

Non-custodial

Mnemonic, private keys and Keystore are generated, encrypted and stored on your device only.

🛡️

Fully local loop

Key generation, signing and data processing all happen locally. No telemetry, no data collection, no log upload.

🧩

Minimal attack surface

Small, auditable codebase with least-privilege design. Fewer features, fewer vulnerabilities.
