Enable DeFi Kickbacks with FinTag
FinTag is a simple way to connect your website to the decentralized finance (DeFi) ecosystem. It uses HTML meta tags to define your wallet address and referral fee structure for on-chain kickbacks.
Required meta tags
<meta property="ican:xcb" content="cb00…" /> <meta property="defi:fee" content="1.00%" />
•
ican:xcb• Your ICAN/XCB address (generated via CorePass)
•
defi:fee• Percentage you want to earn from each successful referral transaction (e.g.
1.34%)• Allowed values:
0.00% to 2.00%• Default value:
0.00%• Up to two decimal places
How referrals work
When a user publishes a payment or donation on your site, the browser usually delivers a Referer header to us. This allows us to validate your FinTag and trigger the DeFi kickback.
Referrer is sent when:
• Users click regular
<a href> links•
rel="noreferrer" is not used• Page uses a standard referrer policy (e.g.
strict-origin-when-cross-origin)Referrer is blocked when:
• Links use
rel="noreferrer" or meta tag <meta name="referrer" content="no-referrer">• HTTPS → HTTP (downgrade) links
• User's browser is in hardened or private mode (e.g. Brave, Arc, Safari, Firefox private)
• Extensions like uBlock Origin, Ghostery, or DuckDuckGo strip headers
Recommendations:
• Use standard
<a href> links without rel="noreferrer"• Keep your site and links using
https:// only• Do not override referrer policy unless required
• Educate your affiliates to avoid referral-blocking setups
• Place your FinTag meta tags inside the
<head> of your HTML document to exact pages you want get kickbacks forAfter generating, place your FinTag meta tags inside the <head> of your HTML document.
