On-Chain Trading: Essential Security Tips#

Remember: in Web3, you are your own bank. While this provides unprecedented financial freedom, it also means security is entirely in your hands. Let's explore how to keep your assets safe with OKX Wallet.

1、Web3 Security Principles: Stay Skeptical#

• Keep sensitive information stored offline; never enter or provide your seed phrase/private key on any website or to any "customer service".
• Ensure all applications are downloaded from official sources; do not trust online search results blindly.
• Be cautious with all links obtained from social media, communities, or search engines.

2、Phishing Attack Scenarios and Preventive Measures#

1. Sources of Malicious Information

   • Fake Website Phishing: Mimicking wallet official websites or DApp pages to trick users into entering their private keys.
     • Preventive Measures:
       • Manually enter the official website address or use bookmarks to avoid clicking suspicious links.
       • OKX Wallet has a built-in anti-phishing plugin that automatically warns users when visiting risky websites.
   • Social Media Phishing:
     • Impersonation Accounts: Attackers copy project logos and names, sending fake links via X replies or private messages.
     • Hijacking Official Accounts: Stealing KOL or project accounts to post phishing information (e.g., Vitalik's account was once compromised).
     • Prevention Tips: Verify the account's official Twitter handle (unique identifier) and be cautious of unverified links.
   • Google Ad Traps: Phishers buy ad slots and disguise URLs as official domains (e.g., "web3.okx.com" vs. "web3.0kx.com").
     • Solution: Always access websites via links provided in the official X bio of the project.

2. High-Risk Scenarios During On-Chain Interactions

   • Malicious Contract Approvals:
     • Phishers trick users into signing approve, permit, or other authorization transactions to transfer assets.
     • OKX Wallet Protection Mechanism: When detecting authorization to EOA (Private Address) or malicious contracts, risk transaction alerts are triggered.
   • Similar Address Poisoning:
     • Phishers create fake addresses that look similar to commonly used addresses (e.g., “0x123…aBc” vs. “0x123…AbC”) to pollute transaction history.
     • Preventive Measures: Always manually verify the complete address when transferring funds and avoid copying from transaction history.
   • Off-Chain Signature Phishing:
     • Phishers steal authorization via offline signatures (e.g., permit for ERC-20 tokens). OKX Wallet Protection: Supports signature content parsing and triggers alerts when encountering malicious addresses.

3. Private Key Leakage Risks

• Common Leakage Channels: ​Trojan programs stealing private keys from screenshots or clipboard data, cloud backup breaches, vulnerabilities in remote control tools, etc.
• Secure Storage Solutions: ​Best Backup Methods for Private Keys & Seed Phrases

3、Wallet Security Tips#

1. Regularly Check and Revoke Permissions

   • Use the authorization management tool in OKX Wallet to periodically clean up unnecessary contract permissions and prevent over-authorizations.

2. Beware of Airdrop Scams

   • Unknown tokens (such as fake ZAPE tokens) may prompt authorization during exchanges. Upgrade OKX Wallet to the latest version to automatically hide risky tokens.

3. Updates and Protection

   • Keep your wallet application and operating system up to date to patch known vulnerabilities.

4、Emergency Response After Phishing Attacks#

1. Immediately Transfer Remaining Assets to a New Address and Revoke All Related Permissions
2. Contact OKX Wallet Customer Support: ​Available 24/7 to assist with stolen asset incidents and provide guidance on blockchain evidence collection.
3. Trace Fund Flow via Blockchain Explorers (e.g., Etherscan): ​Contact relevant projects to freeze assets if possible (e.g., USDC blacklist mechanism).

Remember the Golden Rule: Asset security comes above all else. By following proper procedures, using available tools, and staying vigilant, you can explore the on-chain world more safely. For further assistance, please visit the OKX Wallet Help Center or contact official customer support.
