Label every address. Turn chaos into context.
Yellowdex keeps context tethered to every address—on explorers, wallets, dashboards, marketplaces, and forums. Save labels to collections and share them with your team.

How it works
Dex-level context in three steps.
Keep your address intel close to the surface. Yellowdex rides along anywhere you see an address and lets you capture, organize, and reuse that knowledge instantly.
Spot an address
Yellowdex floats beside any address you see on explorers, wallets, dashboards, and marketplaces.
Label it in a tap
Assign an entity, add a label and color-coded tags. Your labels appear everywhere you browse.
Save to a collection
Organize labels into collections (like a contact list) and share them with teammates or the public.
What you get
Built for power labelers.
Structured, fast, and always on top of the page you are reading.
Works wherever you browse
Detects addresses automatically on any page you visit—no special integrations needed. If a site shows an address, Yellowdex will find it.
Smart search with filters
Search with prefix syntax: a:0x123 for addresses, l:exchange for labels, e:uniswap for entities. Filter by current page or labeled status.
Signal what matters
Create custom color-coded tags to mark addresses however you choose. Pre-built risk categories coming soon.
Sync across devices
Connect your wallet to sync labels across browsers, or keep everything local—your choice. Backups and exports always available.

This beta adds a one-click way to turn all your address labels on or off, widens where labels show up, and fixes a case where some labels could stay hidden longer than they should.
What Changed
- Show or hide every label with one click. A new eye button in the popup header lets you switch all address labels off — addresses go back to how the page normally shows them — and back on again whenever you like. The setting follows you across your signed-in browsers. Changes take effect the next time a page loads.
- More contract names recognized. Labels now appear on named contract links that show a name up front and keep the full address in the tooltip, so you'll see your labels in more places.
Fixes & Improvements
- Labels from shared collections you've just joined no longer stay hidden while things catch up — they now appear as soon as the collection finishes syncing, instead of waiting out the cache.
Notes
- The show/hide switch applies everywhere at once. To hide labels on just certain sites, keep using the Excluded Sites list.
