• Interact with your contract:

• Ownable Pattern: Restricts access to certain functions to the contract owner.

• Pausable Pattern: Allows the contract to be paused or unpaused.

Example Workflow:

• Write your smart contract in Remix IDE, regularly checking the gas estimates.
• Deploy the contract on a test network using Truffle or Hardhat.
• Use Solidity Coverage to generate a gas report and identify optimization opportunities.

• Decentralized: Operates on the blockchain, not controlled by any single entity.
• Trustless: Executes automatically when conditions are met, without requiring trust between parties.
• Immutable: Once deployed, the contract's code cannot be changed, ensuring the terms are fixed.

Before writing a smart contract, we need to set up a development environment. Here’s what you need:
