Beginner's Guide to Solidity: Building Smart Contracts with Remix IDE for Exploring NFTs

Updated: Jun 12, 2023

Coding neophytes looking to enter the world of blockchain development often find themselves attracted to Solidity, the programming language used for writing smart contracts on the Ethereum platform and many other compatible blockchains. This article serves as a comprehensive guide for beginners, highlighting the essential concepts of Solidity and its integration with Remix IDE. Additionally, we delve into the fascinating realm of non-fungible tokens (NFTs), tracing their birth, the ERC721 standard, and the pioneers who developed the first NFT smart contracts.

Understanding Solidity and Remix IDE:

Solidity is a high-level, statically typed programming language designed explicitly for developing smart contracts on blockchain platforms like Ethereum. Remix IDE, an online development environment, offers an accessible and user-friendly interface for writing, testing, and deploying Solidity smart contracts. Let's explore some key features and advantages of Remix IDE:

1. Simplicity and Ease of Use: Remix IDE provides a beginner-friendly coding environment, making it an excellent starting point for those new to Solidity. Its intuitive interface allows developers to write, compile, and debug smart contracts without requiring complex setups.

2. Built-in Compiler and Debugger: Remix IDE includes a built-in Solidity compiler, enabling developers to compile and check their code for errors directly within the IDE. Additionally, it offers a robust debugger that assists in identifying and resolving issues during the development process.

3. Deployment and Testing Tools: Remix IDE simplifies the deployment and testing of smart contracts. It supports both local and global deployment options, allowing developers to interact with their contracts through a built-in web interface or a local blockchain development environment like Ganache.

4. Code Templates and Autocomplete: Remix IDE provides code templates and autocomplete suggestions, streamlining the development process. These features assist beginners by reducing the likelihood of syntax errors and enhancing code readability.

Pros and Cons of Remix IDE:

While Remix IDE offers numerous advantages, it's essential to consider its pros and cons before getting started:


- User-friendly interface suitable for beginners

- Integrated compiler and debugger for efficient code development

- Robust deployment and testing tools for hassle-free contract interaction

- Code templates and autocomplete for improved productivity

- Continuous updates and community support


- Limited offline functionality as Remix IDE operates primarily online

- Potential security concerns associated with using an online development environment (precautions like offline development and secure deployments can mitigate risks)

NFTs: The Rise of Digital Collectibles:

Non-fungible tokens (NFTs) have emerged as one of the most exciting applications of blockchain technology. Unlike cryptocurrencies that are fungible and interchangeable, NFTs represent unique digital assets, such as artwork, music, virtual real estate, and more. The concept of NFTs gained significant attention in recent years, leading to an explosion of creativity and innovation in the digital art world.

The ERC721 Standard and the First NFT Smart Contracts:

The ERC721 standard, introduced by Dieter Shirley in 2017, revolutionized the way NFTs are created and managed. ERC721 stands for Ethereum Request for Comments 721 and defines the basic set of rules and functionalities for NFTs on the Ethereum blockchain. This standard enabled the development of the first NFT smart contracts.

The first-ever NFT smart contract, CryptoPunks, was developed by Larva Labs in June 2017. CryptoPunks introduced 10,000 unique 24x24 pixel art characters, each with distinct attributes. These NFTs became highly sought after, paving the way for the subsequent NFT boom. Another notable example is the CryptoKitties project, also created by Dapper Labs in the same year. CryptoKitties allowed users to collect, breed, and trade virtual cats, further driving the popularity of NFTs.

Learning Resources: Hashlips YouTube Tutorials

For beginners interested in diving into the world of NFTs and learning how to write smart contracts, the Hashlips YouTube channel offers an excellent resource. Hashlips provides step-by-step tutorials and guides for creating NFTs using Solidity and ReactJS to build a Web3 front end (website for users). These tutorials cover topics such as minting, metadata, royalties, and deploying NFT contracts on the Ethereum blockchain.

Solidity and Remix IDE provide a perfect starting point for beginners looking to explore the exciting realm of smart contract development. Remix IDE's user-friendly interface, integrated compiler and debugger, and deployment tools make it an ideal choice for beginners. Additionally, the rise of NFTs and the ERC721 standard have opened up endless possibilities in the world of digital collectibles. Learning resources like the Hashlips YouTube tutorials can further enhance your understanding and skills in creating NFTs using Solidity. So, get ready to embark on your coding journey and unlock the potential of decentralized applications with Solidity and Remix IDE.
