Browser Extension Integration
For sites that cannot integrate the SDK directly, the browser extension provides a zero-integration bridge.
How it works
- User installs the extension
- Your site posts
{ type: "TRUSTLAYER_VERIFY" }towindow - Extension responds with a signed payload containing the Trust Score
- Your site verifies the payload using the public TrustLayer key
