Web3 wallets serve as gateways to decentralized finance, but they're also prime targets for scammers. Fraudsters lure users with fake mining schemes, airdrops, or high-yield activities to steal assets through malicious links, unauthorized wallet access, or phishing for seed phrases/private keys. Due to blockchain's irreversible nature, stolen assets are rarely recoverable—making prevention critical.
Core Security Principles:
✔ Never click suspicious links
✔ Verify project authenticity before authorization
✔ Double-check wallet addresses
✔ Guard seed phrases/private keys like cash
Immediate Actions If Your Wallet Is Compromised
- Transfer remaining funds to a secure address immediately
- Delete the compromised wallet (Path: Wallet homepage > Top-left icon > Wallet Management > Edit > Delete)
- Create a new wallet and securely store handwritten seed phrases offline
Top 5 Web3 Scam Tactics & Countermeasures
1️⃣ Malicious Wallet Authorization via Phishing Links
How it works:
- Fake high-yield campaigns (mining/airdrops) using spoofed "official" links
- Unsolicited token transfers prompting wallet authorization
Defense:
👉 Always verify project URLs before connecting wallets
2️⃣ Unauthorized Permission Modifications
TRC-chain exploitation:
- Scammers offer discounted gift cards/fuel coupons

Red flags:
⚠ "Permission change" warnings during transfers
3️⃣ Address Spoofing Attacks
