Quickstart

Get up and running with SHIELD in just a few minutes. This guide will walk you through creating your first secure link.

​
Prerequisites

You’ll need:
  • A web3 wallet (MetaMask, Coinbase Wallet, Rainbow, etc.)
  • Some ETH on Base (for gas fees when creating policies)

​
Step 1: Connect Your Wallet

  1. Go to app.shieldhq.xyz
  2. Click “Connect Wallet” in the top right
  3. Select your wallet and approve the connection
  4. Sign the SIWE (Sign-In with Ethereum) message
SIWI is a secure way to authenticate using your wallet. You’re not spending any ETH, just proving ownership of your address.
  1. Open the Shield dApp
  2. Choose your content type:
    • File: Upload any file (images, documents, etc.)
    • Message: Type a text message
  3. Set access conditions:
    • Recipient: Enter the wallet address of who can access this
    • Expiration: Choose when the link expires
    • Max Attempts: Set how many times it can be accessed
  4. Click “Generate Link” and approve the transaction
Important: The secure link containing the decryption key is only shown once. Copy it immediately and store it safely. If you lose it, you cannot recover it—not even the SHIELD team can help.
Send the secure link to your recipient through any channel (email, DM, etc.). The link looks like: 
https://app.shieldhq.xyz/r/policyId#def456
The part after # is the decryption key. It’s never sent to any server.

​
Step 4: Monitor Access

Visit your Profile to:
  • See all your created links
  • Check access attempt logs
  • Revoke links early if needed
