Vyper is a programming language that was developed by the Ethereum Foundation in order to create smart contracts for the Ethereum blockchain network. It is an alternative to the popular Solidity language and is designed to be more secure, readable, and auditable than its predecessor. Vyper is a high-level programming language that is designed to be easy to learn and use, even by developers who are new to the smart contract space. It uses Python-style syntax and relies on a static type system to reduce the number of errors that can occur in a smart contract program.
