# Yellowdex

> Yellowdex is a Chrome extension that labels every Ethereum address you see while browsing — on explorers, wallets, dashboards, marketplaces, and forums. Save labels to collections and share them with your team.

## What Yellowdex does

Yellowdex floats an overlay beside any Ethereum address you encounter on the web. You can assign an entity name, add a label, apply color-coded tags, and save everything to a collection. Labels are local-first: you control what stays private and what gets shared.

## Key features

- **Works wherever you browse** — Detects addresses automatically on any page. Supports Etherscan, Twitter/X, Discord, docs sites, and more.
- **Smart search with filters** — Prefix syntax: `a:` for addresses, `l:` for labels, `e:` for entities. Filter by current page or labeled status.
- **Custom color-coded tags** — 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.
- **Collections & sharing** — Organize labels into collections and share them via read-only links. Recipients import the entire collection with one click.

## How it works

1. Spot an address — Yellowdex floats beside any address on explorers, wallets, dashboards, and marketplaces.
2. Label it in a tap — Assign an entity, add a label and color-coded tags. 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.

## Releases

### v0.1.3-beta (v0.1.3-beta) — Apr 27, 2026

### 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.


### v0.1.2-beta (v0.1.2-beta) — Apr 22, 2026

### New Features

- **Site exclusion list** — Disable the extension on specific sites where DOM injection causes issues. Default exclusion list fetched from server, with the ability to add/remove sites in Settings. Ships with `*.gitbook.io`, `docs.github.com`, and other known-problematic sites pre-excluded.

- **Standardised label display** — System address labels now display as `{entity}: {label}` (e.g. "Uniswap V3: USDC/WETH (0.3%)"). Addresses without an entity fall back to `{0xabcd}: {label}` using the truncated address prefix.

- **Legacy prefix cleanup** — Labels where users previously typed a redundant address prefix into the label field (e.g. `0xce2e: Hot Wallet` under entity "Uniswap") no longer display the double prefix. Now shows cleanly as "Uniswap: Hot Wallet" instead of "Uniswap: 0xce2e: Hot Wallet".

- **Cleaner label modal** — The label input no longer pre-fills with the address prefix; placeholder now reads "Descriptive label (e.g. Hot Wallet)".

### Bug Fixes

- **Contenteditable fix** — The extension no longer injects into rich text editors (Google Docs, Notion, etc.), preventing repeated emoji/element duplication.

- **Old cache compatibility** — System labels from older cache entries now display correctly and pre-populate the modal with the correct entity and label fields.

### v0.1.1-beta (v0.1.1-beta) — Apr 4, 2026

## What's Changed

  - Automatic address labels — Well-known addresses (e.g., Uniswap V3 pools) are now labeled automatically on any page, no sign-in required.
  - System collections — Browse and toggle system-maintained collections like Uniswap V3 (56k+ addresses) in the popup's collection dropdown and Manage
  Collections view.
  - Save to My Collection — Click edit on any system-labeled address to save it to your own collection with pre-populated data.
  - Visual distinction — System labels appear in purple to differentiate from your personal labels.

### v0.1.0-beta (v0.1.0-beta) — Mar 9, 2026
