A smart contract is a self-executing program that runs on a blockchain and automatically enforces the terms of an agreement when predefined conditions are met.

Some Key features of smart contracts are:

1. Autonomous: Once deployed, they operate without human intervention.

2. Immutable: The code cannot be changed after deployment (unless designed with upgradeability).

3. Transparent: Anyone can inspect the code and behavior on the blockchain.

4. Trustless: Parties don’t need to trust each other—only the code.

Example:

A smart contract for crowdfunding might work like this:

1. If the total contributions reach $10,000 by a certain date, the funds are released to the project.

2. If not, the money is refunded to the contributors.

Smart contracts are commonly written in languages like Solidity (for Ethereum).
