# Security 

### Overview / why it matters

Most losses come from basic mistakes or scams. A few habits greatly reduce risk.

### Core concepts

* Seed phrase security: Store offline, never type into websites.
* Phishing: Fake sites/messages that steal keys or funds.
* Fake tokens: Look-alike contracts to trick buyers.
* Approvals/allowances: Permission for a contract to move your tokens.
* Revoke: Remove a token approval you no longer need.

### Key takeaways

* Bookmark official links; do not click random DMs.
* Verify contract addresses before interacting.
* Regularly review and revoke old approvals.
