What are Smart Contracts?

Learn the definition, purpose, and key characteristics of smart contracts as immutable, self-executing code on the blockchain.

Welcome to Smart Contracts!

Imagine a contract that executes itself automatically when certain conditions are met, without any human intervention or third party.

That's essentially what a Smart Contract is! It's a fundamental building block of Web3 and powers many decentralized applications.

Contracts on the Blockchain

Traditional contracts are written in legal language and enforced by courts or institutions. Smart Contracts are different.

They are lines of code stored and run on a blockchain. This code defines rules and executes actions automatically when those rules are met.
