Risk Management
Primary Risk Categories
Smart Contract Risk
The risk that protocol code contains vulnerabilities that could be exploited. Mitigation: Only use audited protocols with proven track records.
Market Risk
Price volatility can lead to losses even with sound strategy. Mitigation: Use stablecoins for base capital, diversify exposure.
Operational Risk
User errors like sending to wrong address. Mitigation: Always double-check addresses, start with test transactions.
Regulatory Risk
Changing legal landscape may affect protocol availability. Mitigation: Stay informed, maintain detailed records.
Best Security Practices
- ✅ Use hardware wallets for amounts over $1,000
- ✅ Enable 2FA on all exchange accounts
- ✅ Verify all contract addresses before interacting
- ✅ Keep software and wallets updated
- ✅ Never share private keys or seed phrases
- ✅ Use separate wallets for different strategies
- ✅ Bookmark official sites to avoid phishing
