A smart contract is code stored and run on a blockchain that executes automatically when preset conditions are met. Think of a vending machine — insert payment, make a choice, receive the item, with no middleman. This guide explains it.
How it works
A smart contract writes "if… then…" rules into code and deploys them to a blockchain; once the trigger conditions are met, the contract automatically carries out the action, with no intermediary [1]. It is like a vending machine: you pay and choose, and the machine delivers the item on its own.

What it can do
Smart contracts let developers build all sorts of decentralized apps (dApps) and tokens [2]. From new financial tools like lending and trading to logistics and gaming experiences, they are widely used — and recorded on the blockchain like any other on-chain transaction.
The bottom line
A smart contract is code that runs on a blockchain and executes automatically under preset conditions, forming the technical foundation of DeFi, NFTs, and many dApps. Understanding it helps you see how on-chain apps work. To keep learning the fundamentals, follow more from Bitbase Academy.
