Vyper is a Pythonic smart contract language that compiles to Ethereum Virtual Machine (EVM) bytecode, emphasizing security, simplicity, and auditability. It ships as a Python-based compiler CLI that generates bytecode, ABI, and IR from .vy contract files.

Use cases

• write secure ethereum smart contracts in a python-like language
• compile vyper contracts to evm bytecode and abi
• alternative to solidity with built-in overflow and reentrancy protection
• audit-friendly smart contract development
• build erc20, erc721, and erc4626 tokens on ethereum
• learn smart contract development coming from python

When to choose

• you want pythonic syntax for ethereum contracts
• security and auditability matter more than feature richness
• you need bounds checking, reentrancy guards, and strong typing enforced by the compiler
• you prefer decidable gas costs and no inline assembly

When to avoid

• you need solidity's full feature set, modifiers, or inheritance
• you target non-EVM chains
• you require the largest ecosystem of tooling and community examples
• you want maximum language expressiveness over simplicity
