WebbSolidity is a statically typed programming language designed for developing smart contracts that run on the Ethereum Virtual Machine (EVM) or compatible virtual machines. [17] Solidity uses ECMAScript -like syntax which makes it familiar for existing web developers; [18] however unlike ECMAScript it has static typing and variadic return types. WebbIn this course, you will learn how code Ethereum smart contracts in Solidity. You will learn the most important language features of Solidity like variables, data types, abstract contracts, interfaces, data locations (storage, memory, stack, call data). Besides that, you learn common coding patterns of smart contracts.
