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.

EtherscanTwitterDiscordDocs

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.

Is the Chrome link live?

We’re finalizing the Chrome Web Store listing. For now the Install button uses a placeholder link—tap it to join the waitlist.

Where do my labels live?

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

Which sites are supported?

Any site that surfaces addresses. We prioritize major explorers, wallets, dashboards, and marketplaces.

Can I collaborate with a team?

Yes. Create a shared collection, generate a read-only link, and keep a single source of truth for labels.

Chrome first. Firefox and Edge are on the roadmap—join the list to be notified.
