Editorial interest 78/100 Selection signal · not a rating of the site

An open-source browser extension for adding private notes, labels, and blacklist flags to X accounts, coins, and developer wallets.

Landing page captured for the 2026-10-27 issue.

For: Solana traders tracking repeat developers and coins
Worth noticing: The site says notes stay in-browser; public addresses go to a Solana node for developer lookups, which can be switched off.

Field notes

The homepage embeds a mock X feed where visitors can add a note, label, or blacklist flag and see the feed change; demo entries are saved only on that page. Install instructions point to v0.5 as a ZIP loaded through the browser’s extension developer mode, while the Chrome Web Store listing is described as still under review. The site says saved notes stay in-browser and public addresses are sent to a Solana node for developer lookups, which can be switched off.
