family A smart contract is a computer program that automatically executes when certain conditions are met. It lives on a blockchain (like Ethereum, BNB Chain, Solana, etc.) and allows agreements without intermediaries.
Code that defines rules
A smart contract is written in a programming language (for example, Solidity on Ethereum).
In that code, rules are established such as:
Who can do what.
What happens when a payment is received.
How funds should be handled.
It's like a traditional contract, but translated into code. In short
A smart contract is:
✔ A program
✔ Decentralized
✔ Secure
✔ Automatic
✔ Transparent
✔ Capable of handling value
It's the foundation of everything that exists on blockchain: DeFi, NFTs, DAOs, Web3, games, and more.
