Ethereum CLI Vault

100% Client-Side Security

No server component, ever. All OAuth token exchanges, cloud storage connections, and authorization processes happen solely on your local machine.

This program is fully client-side and will never have any server component. Your private keys never leave your device - only encrypted data is stored in the cloud.
