Super excited to announce (the world's first?) free private onchain address book for websites and CLI! Label your web3 addresses on any site and any chain. I'll submit to the Chrome Web Store soon, but for now download from this repo: https://github.com/aspiers/rolod0x#readme

You'll never have to wonder what 0x8368A7140ad2Fe...blah means ever again.

Labelling is as quick as a couple of mouse clicks and typing the name in.

As you build your address book, you can instantly retrieve entries by pressing a hotkey (configurable) and then searching.

The address book is plain text, so it's super simple to edit, share, import, export etc.  Oh, and there's a dark mode theme!

Let's talk privacy.  Your address book never leaves your browser.  And for extra paranoia (and convenience), you can control which sites the extension is active on.

Also you can control exactly how it looks on a site when an address is replaced by your private label.

I'm proud to release this as Free / Open Source software, to help the usability of the web3 space and help it scale.  (Let's face it, we all know we still have a long way to go on making web3 UX friendlier.)  "Public goods are good!", said a wise man (@owocki) more than once.

Installation only takes a few minutes so please give it a try.  I'd love to hear feedback.  And if you like it, share it with your friends!

BTW for now, it's only tested on Chrome / Chromium / Brave, but ensuring it works on Firefox is top priority after submitting to the Chrome Web Store.  All work is tracked at

How does this $DEGEN thing work? I'm behind the times 😆

I have needed this for so long and had no idea how badly.

Sweet! Too much to say in a cast. Just emailed you.
