About

BlackHart shows you how risky a DeFi protocol or prediction market is — before you interact with it.

As you browse, BlackHart overlays the BlackHart Risk Index (BRI): a 300–1000 security score (higher is safer), shown inline on the pages you already use. It works across the places you meet DeFi and prediction markets — decentralized exchanges and lending apps, block explorers, token-data sites, wallet dashboards, and prediction-market platforms — so you can judge risk in context, without leaving the page.

What you get:
• Live BRI score chips on 100+ scored protocols and prediction markets, wherever they're referenced
• Per-token risk on swaps, so you see the underlying protocol's risk before you sign
• Risk chips on links and cashtags in social posts
• A recent-hacks feed and alerts, so you hear about exploits early
• A pre-transaction advisory that flags risky interactions — advisory only, it never blocks you
• Click any chip to open the full security report at blackhart.io

Free forever for live scores. Paid Starter and Pro plans raise daily limits and unlock the full REST API.

Privacy: BlackHart reads pages locally only to detect which protocol or token is referenced — it never collects page content or your browsing history. Optional anonymous usage analytics (a random install ID and which supported sites showed a score) help us improve coverage. Your API key is stored on your device and used only to fetch your scores. We never sell your data. Full policy: https://blackhart.io/privacy
