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.

Generate a share link for any collection and send it to your team. Recipients import the entire collection — entities, labels, and signals — with one click from the link.

Improvements
Address label prefill restored — The label input once again pre-fills with the first 6 characters of the address (e.g.
0xd8dA) when labeling an unlabeled address. This was removed in v0.1.2-beta but user feedback showed it made the labeling flow significantly faster — just pick an entity and save.Smarter display format — Labels now adapt based on whether an entity is set:
- With entity:
Uniswap: Hot Wallet - Without entity:
Hot Wallet
Previously, addresses without an entity would show a redundant
{0xabcd}: {label}format. Now they display the label cleanly on its own.- With entity:
