How to use a new DeFi protocol safely

Reviewed 2026-06-25

To use a new DeFi protocol safely: verify the official URL, start with a small amount, prefer exact-amount approvals over unlimited ones, read every signature request, and revoke approvals when you are done. Most DeFi losses come from approvals and fake front-ends, not the protocol itself.

Why this matters

Trying a new DeFi protocol is normal. The risk is rarely the math — it is connecting to a fake front-end or leaving an unlimited approval open afterward. Threats work because they look ordinary and create urgency. The fix is simple: verify before you trust.

The safe steps

Verify the official URL; avoid search ads and DM links
Prefer exact-amount approvals over unlimited
Read and understand every signature before signing
Revoke approvals when you finish using the protocol
