Overview

Would you buy a phone which didn’t have an address book feature? Of course not - that would be ridiculous! You’d never know who was calling you, and making phone calls would be painful.

What about a phone which had an address book but required you to publish all the entries so that the whole world could see them? Of course not - that would be a massive privacy violation!

So why accept anything less when using web3 and blockchains?

Well, you don’t have to any longer! rolod0x is a free cross-browser extension providing a totally private onchain address book which instantly makes every web3 website more usable and all your addresses more accessible.

For example, take: this randomly-picked transaction on etherscan:

After labelling the From and To addresses in rolod0x, it now looks like this:

Not only that, but whenever these addresses appear on any other website, they will now be labelled in this human-readable way!

Features

• Completely free and Open Source!
• Completely private local-only web3 address book.
• Automatically translates blockchain addresses to human-readable labels.
• Add entries directly from within a web page, by right-clicking on an address.
• Instantly look up an address via a keyboard shortcut.
• Quick actions to copy addresses, search, or view on block explorers.
• Works on any website.
• Works on any EVM-based blockchain (and could easily support other chains in the future).
• Should work on Chrome, Chromium, Brave, or any other browser in the Chrome family.
• Should work on Firefox (see https://github.com/rolod0x/rolod0x/issues/19).
• Command-line version for translating addresses output on the terminal.
• Light and dark themes.
• Named using a triple pun.

Thanks

Thanks to all contributors. Some special mentions:

• @fregante for all his great npm modules, several of which are used by rolod0x.

• @jonghakseo for https://github.com/Jonghakseo/chrome-extension-boilerplate-react-vite which was a great starting point for a React-based MV3 extension.

• Miles Essex for some fantastic design work which freed up my time to focus on technical work. Check out his exciting project Rails which generates dynamic, interactive maps visualising DeFi transactions!

• The awesome team at my startup Toucan for being early beta testers and encouraging me to keep working on this project. In particular, thanks to Alex Haase for brainstorming with me and coming up with the perfect name!

• Dalton Maag and Canonical for the Ubuntu font whose 0x gave me the inspiration for the logo.

• ricmoo for the wonderful ethers Javascript library.

Except where otherwise stated, this extension is licensed under the GNU General Public License v3 or later. See LICENSE.txt for details.

This Free Software license was chosen because its copyleft property ensures that rolod0x remains a public good whereby:

Why is there also a LICENSE file including the Expat (“MIT”) license?

This extension is based on https://github.com/Jonghakseo/chrome-extension-boilerplate-react-vite/ released under the permissive Expat (a.k.a.
