O Vyper é uma linguagem de programação orientada a contratos bem estabelecida para o EVM que se esforça para fornecer auditabilidade superior, facilitando aos desenvolvedores a produção de código inteligível. De fato, um dos princípios do Vyper é tornar praticamente impossível que os desenvolvedores escrevam códigos enganosos.
Neste capítulo, analisaremos os problemas comuns com contratos inteligentes, apresentaremos a linguagem de programação de contratos Vyper e a compararemos com a Solidity, demonstrando as diferenças.
Vulnerabilidades e Vyper
Somente em 2023, quase US$ 2 bilhões foram roubados devido a vulnerabilidades de contratos inteligentes no ecossistema Ethereum. As vulnerabilidades são introduzidas nos contratos inteligentes por meio do código. Pode-se argumentar com veemência que essas e outras vulnerabilidades não são introduzidas intencionalmente, mas, independentemente disso, o código indesejável do contrato inteligente evidentemente resulta na perda inesperada de fundos para os usuários da Ethereum, e isso não é o ideal. O Vyper foi projetado para facilitar a criação de código seguro ou, da mesma forma, para dificultar a criação acidental de código enganoso ou vulnerável.
Comparação com o Solidity
Uma das maneiras pelas quais o Vyper tenta tornar o código inseguro mais difícil de escrever é omitindo ...
