Smart Contracts 101

1. What Are Smart Contracts?

Code on blockchains (e.g., Ethereum) that runs automatically—e.g., swaps on Uniswap. But scams hide in bad code, costing $500 million in 2024 (DeFiLlama).

2. Why They’re Risky

Unaudited contracts can have backdoors—devs drain funds or freeze tokens. Once deployed, they’re immutable.

3. Checking Safety

4. Basic Verification

No coding needed—search contract addresses on explorers. If it’s not verified or has odd transactions, steer clear.
