To clarify, Smart contracts provide self-executing contracts with the terms of the agreement written directly into code. 

Hence, Solidity allows developers to write, test and deploy smart contracts on the Ethereum blockchain. Furthermore, these contracts help to facilitate, verify, and enforce the negotiation or performance of a contract. They can also be used to create decentralized applications (dApps) that run on the Ethereum network. 

To sum up, you can call Solidity a statically typed and open-source language. This means that variables have to be declared with their types. Moreover, it also supports inheritance, libraries, and complex user-defined types. It comes with a highly active community to develop effective tools and features of Solidity to build on Ethereum easily.

Why Should You Become a Solidity Developer?
