Frequently Asked Questions

What is the single most important NFT security measure I can implement today?

The most impactful security measure for most collectors is transitioning to a hardware wallet combined with regular permission auditing. This addresses the most common attack vectors while being relatively simple to implement. Start with a reputable hardware wallet and regularly use tools to audit and revoke unnecessary contract approvals.

Are certain blockchains more secure than others for NFTs?

While all major blockchains implement strong cryptographic security, they differ in security models and maturity. Established chains have undergone more extensive security testing and have larger security researcher communities identifying vulnerabilities. However, security ultimately depends more on individual practices than blockchain choice. Newer chains may offer improved features but often have less battle tested security.

How can I verify if an NFT project has been properly audited?

Look for published audit reports from reputable security firms on the project's website and GitHub. Legitimate projects will prominently display these reports. You can also verify the auditor's signature on verification platforms or contact the auditing firm directly to confirm the audit's authenticity. Industry databases also maintain records of verified audited projects.

What should I do if I accidentally approved a malicious contract?

Act immediately! Use a service to revoke the approval as quickly as possible. Then transfer any valuable assets to a new, secure wallet, as the compromised wallet should be considered permanently unsafe.
