Yellowdex

Yellowdex is the Chrome extension that lets you label crypto addresses wherever you browse, organize collections, and share them with your crew.

[Yellowdex @yellowdex_ai]

Yellowdex has now indexed 12,132,475 addresses across 24 collections as of July 20, 2026. The top indexed collections are Uniswap V2 with 3,568,660 addresses, PancakeSwap V2 with 2,646,428, and Uniswap V3 with 2,150,930.

@crypto__asad Exactly why we built Yellowdex. You can't verify 42 characters by eye — but you can verify a name. Our extension floats a label next to every address you see, so before you hit send you're checking "Me: Hot Wallet," not 0x7a2…f9c. Recognition > luck.

Yellowdex speaks Plasma now 🌞

Three new collections, live today:
· Plasma One — checking & deposit addresses from @Plasma
· Uniswap V3 — pool addresses from @Uniswap
· Lithos — AMM pairs from @lithos_to

46,000+ labeled addresses on a brand-new network — and the index grows daily.

Your address labels don't touch our servers unless you say so.

Yellowdex has always been local-first: everything works fully offline, and only syncs once you sign in with your wallet.

[Yellowdex @yellowdex_ai]

Sync is back.

We removed the sync feature for a while. But in v2.0, it returns — rebuilt from the ground up with wallet sign-in, local-first storage, and real conflict resolution.

Same labels, every browser and machine you use.

Yellowdex has indexed 11,447,979 addresses across 21 collections as of June 23, 2026. Top collections by indexed addresses: Uniswap V2 at 3,554,892, PancakeSwap V2 at 2,605,096, and Uniswap V3 Base at 1,869,276.

The Humanity ($H) hack, with yellowdex extension enabled.

Attacker wallets, the malicious bridge proxy, the seed wallets — 🏷️ labeled inline on Etherscan as you scroll.

Raw hex turns into a readable map of the exploit. No 14 open tabs.

[Yellowdex @yellowdex_ai]

Address context should not live in a separate spreadsheet.

Yellowdex rides alongside the pages you already use, from explorers to dashboards, so labels appear right where the wallet address does.

Less tab switching. More context.

[Yellowdex @yellowdex_ai]

We have over 7,000,000 labelled addresses.

That means more wallets, contracts, and counterparties are recognized wherever you browse.

Available now on the Chrome Web Store.

Our indexer occasionally meets quirky ERC-20 tokens.

FLNT 0x5c46f9abb2858aa27e3bf88f619e7f7bd408f00f on Ethereum is a neat example: its `name()` and `symbol()` return values like `Flaunt` and `FLNT`, followed by invisible null-byte padding.

Token metadata is messy input. Yellowdex normalizes the messy bits so labels stay readable.

[Yellowdex @yellowdex_ai]

Yellowdex is private by default.

Labels you create stay in your local browser. Nothing is synced online unless you choose to.

Need to move labels to another browser or machine? Export/import them as JSON, or log in with your wallet to sync.

[Yellowdex @yellowdex_ai]

Before Yellowdex: a wall of anonymous addresses.

After Yellowdex: labels, tags, and context right where you browse.

We refreshed the landing page to show you how it works:

[Yellowdex @yellowdex_ai]

What changed:

- create new entities even when they partially match existing ones
- Label Address no longer stacks duplicate modals
- label editing works better from iframes and popup
- CEX deposit address collections are now labeled

[Yellowdex @yellowdex_ai]

Yellowdex v0.1.4-beta is live.

This one is about making address labels feel boring in the best way: fewer modal quirks, cleaner entity creation, more reliable popup editing, and a refreshed landing page.

[Yellowdex @yellowdex_ai]

What changed:

- Label prefill restored (removed in v0.1.2, back by popular demand)
- With entity: "Uniswap: Hot Wallet"
- Without entity: just "Hot Wallet" (no more redundant 0x prefix)

Small tweak, big time saver when labeling in bulk.

[Yellowdex @yellowdex_ai]

Yellowdex v0.1.3-beta is out!

We brought back address label prefill — the input pre-fills with the first 6 chars (e.g. 0xd8dA) so you can just pick an entity and save.

Also: smarter display that adapts to whether an entity is set.

[Yellowdex @yellowdex_ai]

just shipped Yellowdex v0.1.2-beta

labels now display consistently as "Entity: Label" everywhere — "Uniswap: Hot Wallet", "Wintermute: OTC Desk", no more guessing

+ you can now disable the extension on sites like Gitbook where it was causing scan issues

0x1F98431c8aD98523631AE4a59f267346ea31F984 means nothing to most people — but it's the Uniswap V3 Factory address.

Yellowdex v0.1.1-beta labels 56,000+ well-known addresses automatically, no login needed.

Onchain should be readable. https://t.co/bjcmJq1eZR

[Yellowdex @yellowdex_ai]

We built Yellowdex because we kept losing track of addresses.

Screenshots in folders. Notes in Notion. Memory failing.

The tools exist (explorers, dashboards) but context doesn't persist.

So we made it persist.

Free, privacy-first.

[Yellowdex @yellowdex_ai]

You see an address on Etherscan.

Then again on DeBank.

Then in a governance forum.

With Yellowdex, you label it once—your context follows everywhere.

Chrome extension. Privacy-first. Free.

For people who need to remember which address is which.

Coming soon!
