What is a Smart Contract?
A smart contract is a self-executing agreement between two or more parties. It operates under predefined conditions set by the participants and runs automatically when those conditions are met, eliminating the need for third-party intermediaries or traditional off-chain contracts.
Essentially, smart contracts leverage the secure and immutable nature of blockchain to ensure trustworthiness and transparency in various transactions, be they financial, legal, or otherwise.
What is a Smart Contract Developer?
A smart contract developer is a professional who possesses the technical skills and knowledge required to design, develop, and implement smart contracts on blockchain platforms.
With a strong background in programming languages such as Solidity or Rust, smart contract developers are well-versed in various blockchain systems like Ethereum, Polkadot, or Cardano.
By combining creativity with technological know-how, these experts play an instrumental role in advancing the functionalities and applications of blockchain technology around the world.

What Do You Need to Become a Smart Contract Developer?
To become a full-fledged smart contract developer, you’ll need to possess a few key skills and expert knowledge. Here are ten things to learn to break into smart contract development.
The Fundamentals of Blockchain
Familiarize yourself with core concepts such as decentralized networks, distributed ledger technology, consensus mechanisms, and various types of blockchains (public or permissioned). Grasping these basics will serve as the foundation for mastering complex blockchain skills.
Knowledge of The Ethereum Blockchain
Ethereum is one of the most popular platforms for deploying smart contracts; hence, having in-depth knowledge about this particular blockchain network will be invaluable. Learn how Ethereum works and its potential applications in various industries before you move forward.
Cryptography and Security
Smart contracts entail financial transactions, so you’ll need to understand cryptography principles to keep your contracts secure. Be sure to familiarize yourself with concepts like public-key encryption, asymmetric cryptography, hashing algorithms, and digital signatures.
Solidity Coding Language
Solidity is the most prevalent programming language for creating smart contracts. Begin by learning Solidity syntax and data types while gaining experience by writing simple yet functional contracts. Find a course that provides comprehensive training in Solidity, like a RareSkills.
Ethereum Virtual Machine (EVM)
Understanding how the EVM executes bytecode generated from compiled Solidity code is critical when creating efficient smart contracts on Ethereum networks. Delve into topics like gas consumption, opcode execution, and how the EVM manages data storage for your education.
Git and GitHub
Git is a widely-used version control system, whereas GitHub serves as a Git repository hosting service. As a developer, mastering these tools will allow you to collaborate with others while writing code, manage your projects effectively, and stay up-to-date with the latest updates.
Truffle Framework Tools
Truffle Framework offers indispensable tools for smart contract development on Ethereum networks. When you become proficient in Truffle, you’ll be able to compile, deploy and test contracts with ease. Truffle also provides other useful functionalities, such as Ganache.
Remix Integrated Development Environment (IDE)
Remix IDE is an open-source tool specifically tailored for the creation and testing of Solidity-based smart contracts. By harnessing its power and user-friendly interface, you can develop smart contracts using available plugins like debuggers directly in your web browser.
InterPlanetary File System (IPFS)
IPFS is a decentralized file storage protocol that allows users to store and share data across multiple nodes with higher reliability than traditional systems. Understanding IPFS will give you more options to store large amounts of data securely when devising decentralized applications.
