# REMIX - IDE

Developing Your First\
Decentralized Applications `dApps` On HeLa Chain

If you have developed dApps on Ethereum or `any EVM compatible chain` before, you will feel at home. It is exactly the same. But if you are new, don’t worry, this document will help you embark on your first dApp development on HeLa chain.\
There many platforms and utilities that you can use to develop dAPP. For example: REMIX, Truffle, HardHat, Foundry, etc.\
We will use REMIX for our first dAPP.\
Visit [http://remix.ethereum.org](http://remix.ethereum.org/)

Our first program is `HelloWorld.sol`

In Remix IDE, you will need to compile with a compatible compiler. Remember to select `Injected provider- MetaMask` in the deployment tab.
