What to watch out for
- Look for an audit. The audit doesn't guarantee security but its absence is a red flag.
- Check TVL and activity. Very low TVL with very high yields is often a yield-trap pattern.
- Read the contract approval. Approval scope (specific amount vs. unlimited) matters. Sei Wallet shows this; always read before signing.
- Don't yolo into new launches. New dApps with no audit, no team disclosure, and very high promised APY: avoid.
- Use the dApps you actually need. A few well-known dApps with limited approvals is much safer than signing approvals everywhere.
