First Steps With Solidity

I’m not entirely sure about writing this, as I’m still figuring things out myself. However, I have gained enough experience to write simpler smart contracts and deploy interactive applications on Ethereum. While I wouldn’t consider myself an expert, if you’re reading this, I’m likely at least 3-6 months ahead of you. In the Solidity world, that’s a significant amount of time. While 6 months of JavaScript experience may not be much, 6 months of Solidity experience could potentially land you a six-figure job.

I’m going to assume you already know a few things:

  • You know what Ethereum is and how to interact with a Web3 site using MetaMask.
  • You’re comfortable in HTML, CSS, Javascript, and React.

Start with the basics Link to heading

Before jumping into building complex projects, it’s essential to have a solid understanding of the fundamentals of Solidity and web3. Familiarize yourself with the syntax, data types, control structures, and functions of Solidity, as well as the core concepts of web3, such as Ethereum, wallets, and smart contracts. I recommend you start for this introductory course. After that, delves into how the architecture of a Web 3.0 application works

Once you have a basic understanding of Solidity and web3, start with simple projects to get some hands-on experience. Examples of simple projects include building a simple token contract, creating a simple dApp, or implementing a smart contract for a game.

Solidity and web3 have vibrant communities with many developers and enthusiasts who are happy to help beginners. Participate in online forums, chat rooms, and social media groups to get help, ask questions, and share your progress.

Learn by doing Link to heading

The best way to learn Solidity and web3 is by doing. Start building real-world projects, experiment with different tools, and iterate on your code. As you work on more complex projects, you will gain a deeper understanding of the concepts and the ecosystem.

Here some ideas for projects:

  • Decentralized Finance (DeFi) applications

DeFi is a popular area of development in the blockchain ecosystem. Some examples of DeFi applications that can be built with Solidity and web3 include lending platforms, decentralized exchanges, and prediction markets.

  • NFT Projects

Try launching your own ERC721 (NFT) token! It’s not too hard if you use the OpenZeppelin standard, and it’s a fun way to practice. Build an NFT Marketplace. Nader has a great guide on this as well.

  • Gaming

Gaming is another exciting area of development in the blockchain ecosystem. You can use Solidity and web3 to build games that utilize non-fungible tokens (NFTs) for in-game assets or create a decentralized autonomous organization (DAO) to govern the game’s development.

  • Supply Chain Management

Blockchain technology can be used to build decentralized supply chain management systems. You can use Solidity and web3 to build a smart contract that tracks the movement of goods, verifies the authenticity of products, and enforces contracts between parties.

  • Voting Systems

Solidity and web3 can be used to build secure and transparent voting systems. Smart contracts can be used to enforce voting rules and ensure the accuracy of the voting process, while blockchain technology can ensure the transparency of the results.
