Web3 wallets serve as gateways to participate in the decentralized world. However, scammers frequently exploit mining, airdrops, and high-yield activities to lure users into clicking unknown links. This can lead to unauthorized wallet access or trick users into revealing mnemonic phrases or private keys, resulting in asset loss. Stolen funds are often difficult to recover due to the anonymity and decentralization of digital assets.
How Can I Safeguard Against Scams?
Stay vigilant and adopt best practices to avoid falling victim to scams:
- Avoid clicking unknown links.
- Refrain from authorizing unknown projects.
- Verify address accuracy.
- Protect private keys and mnemonic phrases.
Additional Protective Measures
- Understand Project Context: Research project backgrounds and contact official customer support if you encounter unusual activities.
- Adopt Safer Web3 Practices: Steer clear of unknown links and avoid authorizing Web3 wallets for unfamiliar third-party apps.
- Take Precautions: Be wary of unknown links or airdrops sent to your Web3 wallet. Regularly review and revoke permissions for suspicious sites.
- Secure Private Keys: Minimize using internet-connected devices to store/transmit private keys on hardware wallets. Avoid screenshots or photos of private keys/mnemonic phrases.
- Beware of Unknown Sources: Never import private keys on unfamiliar websites or use wallets from unverified sources. Scan for malware or viruses if anomalies are detected.
- Offline Data Storage: Keep sensitive information (e.g., private keys, passwords) confidential. Use hardware backups like paper stored offline.
- Verify On-Chain Addresses: Double-check entire addresses before transactions. Halt immediately if irregularities are found.
- Use Legitimate Services: Avoid suspicious ads offering gift cards, fuel cards, or recharge services. For legitimate recharges, use addresses provided by recipients.
What If My Wallet Is Compromised?
- Transfer remaining assets to a secure address immediately.
Delete the compromised wallet and create a new one if needed.
- To delete: Navigate to Web3 Wallet > Wallet Management > Edit Wallet > Delete.
- Securely back up your wallet’s mnemonic phrase and private key. Avoid screenshots to prevent data leaks.
- Manually transcribe the mnemonic phrase and store it safely. Avoid authorizing unknown third-party software.
