What is a smart contract?

A smart contract is a program stored on a blockchain that automatically executes actions when predefined conditions are met.

It removes the need for manual processing or intermediaries.

🤔 Why smart contracts matter

Smart contracts help:

automate transactions
reduce human error
increase transparency

They are a key component of many blockchain-based systems.

How smart contracts work

Smart contracts follow simple logic:

if a condition is met
then an action is executed

Once deployed, they operate automatically on the blockchain.

Where smart contracts are used

Smart contracts are commonly used in:

DeFi applications
token issuance
automated transactions

Example

A smart contract may release funds automatically once certain conditions are fulfilled, such as receiving confirmation of a transaction.

In summary

Smart contracts are self-executing programs that automate processes on the blockchain, enabling efficient and transparent transactions.
