Vyper is an open-source smart contract language for Ethereum, designed to make code more secure, readable, and straightforward to audit. Its Python-inspired syntax helps developers express contract logic clearly, while built-in protections such as overflow checking, reentrancy guards, and bounds checking reduce common language-level risks. Vyper’s compiler turns high-level code into optimized EVM bytecode, aiming to deliver efficient gas use without requiring developers to write assembly.

The Vyper project provides documentation, learning resources, code examples, and integrations with popular development environments and frameworks, including Titanoboa, Moccasin, Apeworx, Hardhat, Foundry, and Remix. Developers can explore real-world examples from projects such as Curve and LlamaLend, follow tutorials, or take a free Python and Vyper course from Cyfrin. The project also supports formal verification research, including machine-checked Vyper and EVM semantics and ongoing work on compiler verification. Independent security audits are available through its GitHub resources. Vyper is supported by sponsors and ecosystem organizations, and welcomes contributions, donations, and partnership inquiries.
