Vyper is a pythonic smart contract programming language for the Ethereum Virtual Machine (EVM). Vyper contracts secure more than $4 billion across multiple chains for major protocols such as Curve, Lido and Yearn.

It is currently the second most popular EVM programming language.

Vyper is an open-source project maintained by a core team of experienced web3 engineers and a number of volunteer contributors. We collaborate extensively with partners across the EVM toolchain, infrastructure, and security ecosystems.

Vyper aims to become the leading choice for smart contract development by offering:

Superior developer experience through pythonic syntax and extensive tooling
Enhanced security with a safe-by-default approach that removes common security footguns
Maximum readability, making contracts easier and cheaper to audit
Optimized performance with 50% smaller bytecode and lower gas costs
Easy onboarding for Python developers

To do so, we are currently working on:

Improving compiler security through regular, extensive audits, automated testing and the use of formal verification methods
Implementing new features (struct packing, traits, generics) to make the language more powerful for developers
Enhancing developer tools and framework integration (Titanoboa, Moccasin, Snekmate)
Continuous improvement of compiler optimization through the Venom backend
Building better documentation and learning resources
