Qsave is a web‑based key management platform that lets users generate, encrypt, and store private blockchain keys in a self‑controlled vault. The client‑side AES‑256 encryption and decentralized storage (IPFS/Filecoin) ensure zero‑knowledge privacy, while a browser extension integrates with Ethereum, Solana and other dApps for seamless transaction signing. It also offers secret‑share backups, activity logs, and open‑source SDKs for developers needing secure, self‑custodied key management.

Problem
Individuals and organizations that use blockchain applications often struggle with securely storing, managing, and accessing their private cryptographic keys, leading to a risk of loss, theft, or accidental exposure.
Solution
Qsave offers a web‑based key management platform that enables users to generate, encrypt, and store their private keys in a secure, user‑controlled vault. The service integrates with popular blockchain wallets and dApps through a browser extension, allowing seamless signing of transactions without exposing raw keys. All key material is encrypted client‑side with a user‑derived passphrase, and the encrypted blobs are stored in decentralized storage, ensuring that only the user can decrypt them. Qsave also provides backup and recovery mechanisms, such as secret‑share distribution, to protect against device loss while maintaining zero‑knowledge privacy. The platform includes a dashboard for managing multiple keys, monitoring usage, and revoking access when needed.
Target Audience
Primary users are crypto enthusiasts, DeFi participants, and blockchain developers who need a secure, self‑custodied solution for managing private keys across multiple wallets and applications.
