Create a simple Hello World dapp

This section covers how to build and run Hello World dapp with different available tools for Rell. You can choose the tool you prefer.

Build and run the Hello World dapp

Set up your dapp using Chromia CLI or VS Code. Create with chr create-rell-dapp, start with chr node start, and test with a query for "Hello World!".

Interact with your dapp

Connect your frontend to a Rell blockchain using postchain-client. Ensure the Rell backend is running, then send transactions and query data.
