security-tools

A category of free tools that let a user connect their wallet to see a complete list of every token approval they've ever signed, and revoke any no-longer-needed approval with one click. The tool itself never moves your assets — its sole function is to help you clearly see which spending permissions you've currently granted to which contracts, and let you actively take them back.

A program where a project publicly offers rewards to security researchers for finding and responsibly reporting vulnerabilities before malicious attackers do, forming an ongoing security defense after deployment.

A physical device that completes identity verification when plugged into a USB port or tapped via NFC. Its core advantage is that it first checks whether the website you're logging into is genuinely the real official domain, and simply refuses to respond if the domain doesn't match — meaning even if you accidentally click into a phishing site that looks nearly identical to the real one, the hardware key still won't hand over verification. That's a layer of protection neither an SMS code nor an app authenticator can provide.
