What is a Cardano Smart Contract?

Cardano Smart Contracts

A smart contract on the Cardano blockchain is a self-executing contract that contains the terms of an agreement between parties. The contract automatically executes when certain conditions are met, without the need for intermediaries.

Here is an example of a simple smart contract on the Cardano blockchain:

pragma solidity ^0.8.0;

contract SimpleSmartContract {
uint256 public value;

function setValue(uint256 newValue) public {
value = newValue;

function getValue() public view returns (uint256) {
return value;

The above smart contract has two functions: setValue and getValue. The setValue function takes a uint256 parameter and sets it as the value of the value variable. The getValue function returns the value of the value variable.

This is just a simple example, but smart contracts on the Cardano blockchain can be much more complex and can handle more complex business logic and rules.

How to Use a Smart Contract?

  1. Writing the contract code: The first step is to write the contract code using a programming language supported by the Cardano blockchain, such as Plutus.
  2. Deploying the contract…
