Crypto Tutorials FAQ

How do I know if a smart contract approval is safe to sign?

Always review wallet transaction requests carefully. Avoid unlimited token approvals unless interacting with trusted protocols, and reject permissions that request unnecessary access to your assets.

What is the main difference between CEX and DEX security?

Centralized exchanges rely on platform security, account protection, and company solvency. Decentralized exchanges provide self-custody but require users to verify contracts, liquidity, and transaction settings themselves.

How often should I revoke crypto wallet permissions?

Unused smart contract approvals should be removed after completing trades or reviewed regularly through trusted blockchain security tools to reduce wallet exposure.
