Crypto users are increasingly worried about wallet vulnerabilities and backdoors, but lack tools to audit their own setups. A security-focused tool could address this.
Build a software tool or browser extension that scans crypto wallets for common vulnerabilities or suspicious behavior. Include educational resources for users.
Monetize through a freemium model, with paid features like deeper scans or custom reports.
The MVP could be a basic scanner that checks for known wallet vulnerabilities.
The main risk is keeping up with evolving threats, so focus on transparent updates and user education.
