SolGuard — Smart Wallet Protection for Solana Mobile

Scan wallet risks. Detect recurring drains. Revoke approvals in one tap. Get your Trust Score.

---

🔥 Problem

Every day, Solana users connect their wallets to dozens of dApps without realizing the long-term permissions they grant. Old token approvals, forgotten program permissions, and hidden recurring transactions can silently drain funds or expose wallets to risk — and most users never find out until it's too late.

---

💡 Solution

SolGuard is a mobile-first wallet security app built natively for Solana Mobile. It gives users full visibility into what has access to their wallet and the tools to revoke dangerous permissions instantly.
