Smart Contracts Explained: What They Are and Why They Matter

Smart contracts are self-executing agreements written in code. They power DeFi, NFTs, and Web3. Here is a plain English explanation for complete beginners.

A smart contract is a program that runs on a blockchain and automatically executes when certain conditions are met, without any human involvement. Imagine a vending machine: you insert the exact amount, the machine dispenses your item with no cashier needed. Smart contracts work the same way — the rules are encoded upfront, and execution is automatic and trustless.
