Is Wallet Highlighter - Crypto Fraud & Risk Tool safe?

Low risk

Wallet Highlighter reads emails and crypto wallet addresses on every page and sends them with the page URL to its servers.

A content script runs on all sites, scans page text for email and wallet addresses, and posts them with surrounding page context, the full page URL and a persistent random user ID to api.wallethighlighter.com. This ID links a user's activity across pages. The report button also sends the chosen address and site to the same service.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.
