Solidity
The primary programming language for writing smart contracts on Ethereum and EVM-compatible blockchains.
In-Depth Explanation
Solidity is a high-level, object-oriented language designed specifically for the EVM. Its syntax resembles JavaScript. Solidity handles contract storage, function calls, and interactions with other contracts. Security is critical—Solidity bugs have caused billions in losses. Alternatives include Vyper (Python-like) and newer languages like Huff (assembly-level).
