š **Crypto 101: What Are Smart Contracts?**
They sound fancy, but theyāre just **code that executes itself** ā no lawyers needed. Letās break it down š

š¤ **What is a Smart Contract?**
A **smart contract** is a self-executing program stored on the blockchain.
Once its conditions are met, it runs **automatically** ā with no third party involved.
š Think of it like:
> "If A happens, then do B."
Itās just code with logic.
---
āļø **Key Features:**
ā
**Trustless** ā You donāt need to trust anyone. Just the code.
ā
**Immutable** ā Once deployed, it canāt be changed (unless designed to be upgradeable)
ā
**Transparent** ā Anyone can view and audit the code
ā
**Fast & Cheap** ā No middlemen = lower fees (especially on efficient chains)
---
š§ **Real-World Examples:**
- š DeFi (e.g., Uniswap): Trades happen via smart contracts, not a central exchange
- šØ NFTs: Minting, ownership transfers, royalties = all handled by code
- š¼ DAOs: Governance decisions are executed via smart contracts
---
š§Ŗ **Example in Solidity (Ethereumās smart contract language):**
```solidity
if (msg.value >= 1 ether) {
sendToken(msg.sender);
}
```
š¬ Translation: āIf you send at least 1 ETH, youāll receive a token.ā

š **Why Itās Revolutionary:**
Smart contracts remove **human error**, **corruption**, and **delay** ā making systems more fair, secure, and efficient.
