How to Use Cascade on Lumera: A Complete Guide to Decentralized File Storage

Decentralized storage is becoming a core part of Web3 — and Lumera’s Cascade makes it incredibly simple to store and share files on-chain.

In this guide, you’ll learn exactly how to use Cascade step-by-step, even if you’re a beginner.

What is Cascade?

Cascade is a feature within Lumera Hub that allows you to upload and store files on-chain in a decentralized way.

Instead of relying on centralized servers, your data becomes:

• 🔐 Secure
• 🌍 Publicly accessible
• 🚫 Censorship-resistant

Each uploaded file generates a transaction record and a shareable link.

Why Use Cascade?

Here’s why Cascade stands out:

• No centralized storage risks
• Permanent and verifiable uploads
• Easy sharing via transaction links
• Fully integrated with Lumera Hub

It’s perfect for proofs, public files, and on-chain data storage.

Step 1: Access Lumera Hub

Go to: 👉 https://hub.testnet.lumera.io

Make sure your wallet is connected before proceeding.

Step 2: Connect Your Wallet

1. Click “Connect Wallet”
2. Choose Keplr or Leap
3. Approve the connection

Once connected, you’re ready to use Cascade.

This link allows anyone to verify and access your file.

Everything is transparent and verifiable.
