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.

1

Spot an address

Yellowdex floats beside any address you see on explorers, wallets, dashboards, and marketplaces.

2

Label it in a tap

Assign an entity, add a label and color-coded tags. Your labels appear everywhere you browse.

3

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.

v0.1.6-beta May 31, 2026

v0.1.6-beta

This beta improves label backup/export behavior and cloud sync compatibility.

What’s New

  • Cleaner JSON label exports for manual backups and restores.
  • JSON import/export now stays separate from cloud sync behavior
  • Export labels to json file continue to use the supported v4 format for backup

Fixes & Improvements

  • Existing locally stored generated tag descriptions are cleaned during export, import, and sync preparation.
  • Cloud sync no longer sends the label-file schema version to the server.
  • Sync pull no longer depends on label-file version fields from the server.
  • Removed display-only network metadata from exported label data while preserving the actual network ID.
  • Improved compatibility for round-tripping labels across export/import and sync flows.

Trust & safety

Built for teams who care about context.

Privacy-first by design. Keep sensitive intel local, and publish only what’s meant to be shared. Export your data, back it up, and keep your notes portable.

Local-first defaults

No surprise syncs—opt in to sharing.

Backups & exports

Export to JSON anytime.

Team-friendly

Share read-only links for collections.

No dark patterns

Clear controls, reversible choices.

Labels are local-first. You choose what to sync, what to export, and what to share with others.
