Introduction

The Cere Developer Console is a comprehensive suite of user-friendly tools designed to onboard App Developers to Dragon 1, the first data cluster in Cere’s Decentralized Data Cloud (DDC). This self-service platform, supported by robust smart contracts, enables DDC Clusters to deliver high-powered, automated data cloud operations tailored to developers' needs.

Using the Developer Console (https://developer.console.cere.network/#/login), you can:

Create an account
Receive 50 free tokens
Create your first bucket
Integrate DDC and Media SDK using step-by-step guides

💡 Note: Please use your desktop for tests! Mobile is currently not supported.

Setting Up Your Environment

Install Node.js and npm (if not already installed):
- Download Node.js

Configuring Your Environment

Create Configuration File:
- Create a new file named ddcc.config.js.
- Add the following content, replacing placeholders with your information:

{
  "signer": "<Path to your encrypted wallet backup file>.json",
  "signerPassphrase": "<The password to the encrypted file>",
  "clusterId": "0x7cfe5ddfafd1f0faba7a1194c12e6a0f3d0d6ce9",
  "bucketId": "<Your bucket ID>",
  "blockchainRpc": "wss://rpc.mainnet.cere.network/ws",
}

The signer should point to your wallet backup file.
The signerPassphrase is the password you've specified for the backup file.
Find your bucketId in the developer console.

You also can find other config options using the CLI tool with --help command line flag.

Uploading Content to DDC

You have two options for uploading content:

Option 1: Use the File Uploader
