FAQ
Our development team has a solid background in programming: professional degrees and at least 6 years of experience in blockchain. HashEx is trusted by the most credible companies in the market, while our certification program was developed by the best, most skilled members of the team. So, yes, it certainly is.
Solidity is the most popular language. It’s an object-oriented and statically-typed language for programming. Rust language allows developers to build high-throughput applications, all thanks to its efficient design. Other examples include JavaScript, Vyper, Yul, FunC, and more. New programming languages appear depending on the needs of developers.
Solidity developers are in high demand due to the increasing popularity of blockchain in general, and Ethereum in particular. Being the most widely used language for smart contracts development, Solidity certainly draws the attention of many companies and projects. Solidity developers have no difficulty finding an application for their skills, and knowledge of this language can help with creating their own dApps.
Test for solidity developers includes several languages and libraries.
For smart contracts, we use Solidity, Truffle, and Ganache. While Web3, Javascript, React & Drizzle are used for integration with the front-end.
