Developer Tools

There are tons of frameworks, tools and resources that will help you create your very own first ÐApp.

Smart contracts are executed in the Ethereum Virtual Machine (EVM), which runs on every full Ethereum node. The most contracts are written in Solidity, and frameworks like Truffle, Embark or Dapp simplify the creation.
