# Crypto Wallet Security 101

Effective management and protection of digital assets in Web 3.0 necessitate a thorough understanding of wallet types and security features. Selecting the right storage option and implementing robust security measures are vital to safeguarding your investments.

### **Types of Wallets:**

* Custodial Wallets: Third-party services offer these wallets, which manage your private keys and transactions. While convenient, they expose users to risks if the provider's security is compromised.
* Non-Custodial Wallets: These give users complete control over their assets by allowing them to manage their private keys and transactions directly. This independence increases security but also places greater responsibility on the user.

### **Wallet Security Practices:**

* Hardware Wallets: These devices, which often resemble USB drives, provide a secure way to manage private keys and perform transactions. Their physical nature requires anyone attempting to access the wallet to have the device in hand, greatly reducing the risk of online theft.
* Hot Wallets: These digital wallets are more accessible and vulnerable to security threats. Strong security protocols, such as robust passwords and two-factor authentication, are vital.

### **Common Vulnerabilities and Prevention:**

* Phishing: A common tactic where attackers impersonate legitimate services to steal credentials.
* Malware Attacks: These can infiltrate devices through downloads or deceptive links. Maintaining updated anti-malware software is crucial.
* Bugs in Wallet Software: Developers frequently update wallet software to fix vulnerabilities that hackers could exploit.

These guidelines can significantly strengthen your crypto wallet's defense against potential security threats. We recommend [CryptoGuard](http://cryptoguard.ai), our AI-powered Web3 security tool that fights back against hackers and protects your assets.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.chaingpt.org/ai-tools-and-applications/cryptoguard-extension-your-web3-shield/crypto-wallet-security-101.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
