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 makes sync feel instant: edits made on another device now show up here in a second or two, instead of waiting for the next sync check.
What Changed
- Near-instant sync. When you add, edit, or remove a label on one device, your other signed-in devices now pick it up within about a second or two. Before this, changes could take up to five minutes to appear.
- Live status in the popup. Hover over the sync status dot and it now shows whether you're connected to the live channel.
Fixes & Improvements
- Sync keeps working normally even when the live connection drops — it quietly reconnects, and the regular check still runs in the background as a safety net.
- Signing in or out reconnects the live channel right away, so you don't have to wait for updates to start flowing.
Notes
- The live channel needs an up-to-date sync server. If you're on an older server, sync still works — it just falls back to the regular periodic check instead of instant updates.
- You need to be signed in for sync to run at all.
