In this smart contract collection, you’ll dive the most insightful Solidity examples for learning and polishing your skills as a Solidity developer and Blockchain engineer. You can also use those as templates when creating your own smart contracts.
Stand on the shoulders of giants! 🦄
🌍 Recommended Tutorials: Before diving into any individual example in this article, you may find it helpful to go over our quickstart into Solidity and our more detailed Solidity Crash Course—both free tutorials on the Finxter blog.
Example 1: Understanding the Solidity Voting Smart Contract
With this article, we are starting a journey of going through smart contract examples in Solidity.
- We’ll first lay out the entire smart contract example without the comments for readability purposes.
- Then we’ll dissect it part by part, analyze it and explain it.
- Following this path, we’ll get a hands-on experience with smart contracts, as well as good practices in coding, understanding, and debugging smart contracts.
