Solidity
An object-oriented, high-level language for implementing smart contracts on various blockchain platforms, most notably Ethereum.
Solidity is the primary language for building smart contracts on Ethereum and other EVM-compatible blockchains. It's designed to target the Ethereum Virtual Machine (EVM) and is essential for anyone looking to build decentralized applications (dApps).
