Risks to Your Private Key and How to Avoid Them

Thanh Tú7/10/2025

1. Why is it important to protect Private Key and Seed Phrase?

 

Private Key and Seed Phrase are like "passwords" for accessing assets in a cryptocurrency wallet. Each wallet has a unique Private Key or Seed Phrase. If users forget, expose, or share these keys, they could lose access to all their assets in the wallet. Therefore, protecting them is essential.

 

2. Types of Attacks and How to Prevent Them

 

2.1. Dusting Attack

 

In a Dusting Attack, hackers send tiny amounts of tokens to a user's wallet to trick them into interacting with the wallet and granting access. To prevent this, users should not engage with unfamiliar tokens and transfer their assets to a safe wallet if necessary.

 

2.2. Phishing Attack

 

Phishing attacks occur when hackers create fake websites or send fraudulent emails to steal sensitive information like Private Key or Seed Phrase. Users must stay cautious and avoid entering sensitive information on suspicious websites or emails.

 

2.3. Malware Attack

 

A malware attack involves installing harmful software or viruses onto a user's device. To prevent this, users should avoid downloading software from untrusted sources and clicking on unknown links.

 

3. Risks of Public Wifi and Free VPN for Crypto Transactions

 

Public wifi networks are vulnerable because they lack proper security mechanisms. Users should avoid using public wifi for crypto transactions. Free VPNs can offer security, but they may have slower speeds. Users can opt for paid versions for better protection.

 

4. Risks When Interacting with Smart Contracts

 

When interacting with smart contracts, users may need to grant access to their assets. However, granting excessive access can be risky. It's safer to limit access and regularly revoke permissions given to third parties.

 

5. Tips for Protecting Private Key and Seed Phrase

 

5.1. Store in Multiple Locations

 

Avoid storing the full Private Key or Seed Phrase in a single location. Breaking it up and varying storage methods helps protect your assets from risks.

 

5.2. Use Cloud Sync and Clear Clipboard

 

Coin98 Super Wallet's Cloud Sync and Clear Clipboard features help encrypt and protect Private Key, preventing hackers from stealing it when using public devices.

 

5.3. Use Multisig Wallets

 

Multisig wallets require multiple signatures to perform transactions, which enhances security. Even if one Private Key is compromised, the assets remain safe.

 

6. Use Multiple Wallets for Different Purposes

 

To safeguard assets, users should use different wallets for various purposes, such as long-term storage, short-term trading, and airdrops. Switching wallets occasionally can also prevent tracking and provide better protection for assets.
