Let’s start building! Creating a blockchain project using the Procotol is easy.


Create a project

Firstly, we need to create a project to receive an API key and start interacting with other endpoints.

curl --request POST \
  --url https://protocol-sandbox.lumx.io/projects/auth \
  --header 'Content-Type: application/json' \
  --data '{
  "name": "My first project",
  "blockchainName": "Polygon"

You will receive a status 201 with an object containing the API key.


Add your API key to all request headers

Now, make sure to insert your key to the headers of all following requests.

Remember to switch <API_KEY>.

Coming up next, let’s create your first contract on the blockchain.
