Installation

Prerequisites

• Node.js: 14.x or later
• Package Manager: npm 6.x+ or yarn 1.22.x+
• Project: Browser extension or web project with package.json

Installation

cd your-project-directory
npm install @reclaimprotocol/browser-extension-sdk

Asset Setup

Add the asset setup script to your package.json:

{
  "scripts": {
    "reclaim-extension-setup": "node node_modules/@reclaimprotocol/browser-extension-sdk/build/scripts/install-assets.js --public-dir=public"
  }
}

Run the setup script:

npm run reclaim-extension-setup

This copies pre-built SDK bundles to your public directory:

public/
└── reclaim-browser-extension-sdk/
    ├── content/
    │   ├── content.bundle.js
    │   └── components/
    │       ├── reclaim-provider-verification-popup.css
    │       └── reclaim-provider-verification-popup.html
    ├── offscreen/
    │   ├── offscreen.html
    │   └── offscreen.bundle.js
    └── interceptor/
        ├── network-interceptor.bundle.js
        └── injection-scripts.bundle.js

Verify installation:

ls -la public/reclaim-browser-extension-sdk/

What Gets Installed

Content Script (content.bundle.js)

• Bridges communication between web pages and extension background
• Injected into pages where verification is needed

Offscreen Document (offscreen.html, offscreen.bundle.js)

• Executes WebAssembly for cryptographic proof generation
• Required for Manifest V3 service workers

Network Interceptor (network-interceptor.bundle.js, injection-scripts.bundle.js)

• Monitors network requests during provider verification
• Captures data for proof generation

UI Components (reclaim-provider-verification-popup.*)

• Pre-styled popup for verification flow
• Customizable through CSS

Troubleshooting

Assets not copying?

• Verify --public-dir path matches your project structure
• Check file permissions on the public directory

Module not found?

rm -rf node_modules package-lock.json && npm install

Build errors?

• Ensure SDK assets are in public/, not imported in your code
• Reference via manifest configuration (see next steps)
