Solidity Practice – Smart Contract Development Journey 🚀

This repository documents my hands-on learning journey in Solidity and smart contract development, following structured learning paths such as Cyfrin Updraft and hands-on practice using Remix IDE. The goal of this repository is to:

• Build strong foundations in Solidity
• Understand real-world smart contract design patterns
• Maintain consistent GitHub activity
• Develop production-grade Web3 development skills

🚀 How to Run & Test These Contracts (Using Remix IDE)

All contracts in this repository can be compiled and tested using Remix ID*.

Step 1: Open Remix IDE

Visit: https://remix.ethereum.org

Step 2: Choose a Contract

Select any contract from the repository, for example:

Contract-1/SimpleStorage.sol

---

Step 3: Copy Contract Code

Open the .sol file and copy the complete contract code.

---

Step 4: Create File in Remix

• In Remix, click Create New File

• Name it exactly:

  SimpleStorage.sol
  

• Paste the copied code.

Step 5: Compile the Contract

• Go to the Solidity Compiler tab
• Select compiler version based on the pragma line
• Click Compile

Step 6: Deploy the Contract

• Go to Deploy & Run Transactions

• Select:

  Environment → Remix VM (London)
  

• Click Deploy

Step 7: Interact with the Contract

Use the deployed contract UI to:

• Call functions
• Read and modify state variables
• Test contract behavior
