This page outlines the Zcash Foundation’s Trademark policy for the use of the Zcash trademarks. If you are aware of any misuse of the Trademarks in any way, we would appreciate you bringing this to our attention. Please contact us as well, to request approval to use one or more of our trademarks.
This document, the “Policy,” outlines the Zcash Foundation’s (the “Foundation”) policy for the use of the Zcash trademarks.
This policy was originally drafted and adopted by the Electric Coin Company (ECC), and is currently enforced by the Foundation as a condition of ECC's transfer of the trademark to the Foundation (see section 5 of the Trademark Donation and License Agreement).
While the Zcash software is available under a free and open source license, the copyright license does not include an implied right or license to use the Zcash trademarks.
The role of trademarks is to provide assurance about the quality of the products or services with which the trademark is associated. But because an open source license allows your unrestricted modification of the copyrighted software, we cannot be sure that your modifications to the software are ones that will not be misleading if distributed under the same name. Instead, this Policy describes the circumstances under which you may use our trademarks.
In this Policy we are not trying to limit the lawful use of our trademarks, but rather describe for you what we consider the parameters of lawful use to be. Trademark law can be ambiguous, so we hope to provide enough clarity for you to understand whether we will consider your use licensed or non-infringing.
This Trademark Policy attempts to balance two competing interests: Our need to ensure that the Zcash Trademarks remain reliable indicators of quality, source, and security; and our desire to permit community members, Zcash users, software distributors, service providers, and others with whom Foundation works to discuss Zcash and to accurately describe their affiliation with us. Striking a proper balance is a tricky situation that many organizations—in particular those whose products are distributed electronically—wrestle with every day and we’ve attempted to balance it here.
The sections that follow describe what trademarks are covered by this Policy, as well as uses of the trademarks that are allowed without additional permission from us. If you want to use our trademarks in ways that are not described in this Policy, please see “Questions” below for contact information. Any use that does not comply with this Policy or for which we have not separately provided written permission is not a use that we have approved, so you must decide for yourself whether the use is nevertheless lawful.
These guidelines are based on the Model Trademark Guidelines, used under a Creative Commons Attribution 3.0 Unported license. If you are aware of any confusing use or misuse of the Marks in any way, we would appreciate you bringing this to our attention. If you are aware of any confusing use or misuse of the Marks in any way, we would appreciate you bringing this to our attention by contacting us via this link. Please contact us via this link to request approval to use one or more of our trademarks.
We want to encourage and facilitate the use of our trademarks by the community, but do so in a way that still ensures that the trademarks are meaningful as a source and quality indicator for our software and the associated goods and services and continue to embody the high reputation of the software and the community associated with it. This Policy therefore tries to strike the proper balance between:
1) our need to ensure that our trademarks remain reliable indicators of the qualities that they are meant to preserve and
2) our community members’ desire to be full participants in the Zcash cryptocurrency.
This Policy covers:
Our word trademarks and service marks (the “Word Marks”)
Always distinguish trademarks from surrounding text with at least initial capital letters or in all capital letters.
Our logos (the “Logos”):
The Zcash logo, yellow, black and white and color
And the unique visual styling of our website and packaging (the “Trade Dress”). This Policy encompasses all trademarks and service marks, whether Word Marks, Logos or Trade Dress, which are collectively referred to as the “Marks.” Some Marks may not be registered, but registration does not equal ownership of trademarks. This Policy covers our Marks whether they are registered or not.
Whenever you use one of the Marks, you must always do so in a way that does not mislead anyone, either directly or by omission, about exactly what they are getting and from whom. The law reflects this requirement in two major ways described in more detail below:
It prohibits creating a “likelihood of confusion” but allows for “nominative use.” For example, you cannot say you are distributing the Zcash software when you’re distributing a modified version of it, because people would be confused when they are not getting the same features and functionality they would get if they downloaded the software directly from us. You also cannot use our logo on your website in a way that suggests that your website is an official website or that we endorse your website. You can, though, say you like the Zcash software, that you participate in the Zcash community, that you are providing an unmodified version of the Zcash software, or that you wrote a book describing how to use the Zcash software.
This fundamental requirement, that it is always clear to people what they are getting and from whom, is reflected throughout this Policy. It should also serve as your guide if you are not sure about how you are using the Marks.
You agree that you will not acquire any rights in the Marks and that any goodwill generated by your use of the Marks inures solely to our benefit.
See Universal considerations for all uses, above, which also apply.
When you redistribute an unmodified copy of our software, you are not changing the quality or nature of it. Therefore, you may retain the Word Marks and the Logos we have placed on the software to identify your redistribution — whether that redistribution is made by optical media, memory stick or download of unmodified source and executable code. This kind of use only applies if you are redistributing an official distribution from the Zcash Github repository that has not been changed in any way.
You may use the Word Marks, but not the Logos, to truthfully describe the origin of the software that you are providing, that is, that the code you are distributing is a modification of our software. You may say, for example, that “this software is derived from the Zcash source code.”
Of course, you can place your own trademarks or logos on versions of the software to which you have made substantive modifications, because by modifying the software you have become the origin of that exact version. In that case, you should not use our Logos. Our source code version therefore does not contain our Logo data files.
You may use the Word Marks to truthfully describe the relationship between your software and ours. Our Mark should be used after a verb or preposition that describes the relationship between your software and ours. So you may say, for example, “Bob’s software for the Zcash cryptocurrency” but may not say “Bob’s Zcash software.” Some other examples that may work for you are:
You must not claim that your software is compatible with Zcash unless your software complies with the Zcash Protocol Specification, published at https://github.com/zcash/zips/tree/master/protocol.
You may use the Word Marks and the Logos to indicate that you accept payment in the Zcash cryptocurrency, or that your product or service supports the Zcash cryptocurrency. Our Word Marks should be used in a way that makes the nature of the acceptance of or support for the Zcash cryptocurrency clear. Some examples of acceptable use include:
This section discusses the use of our Marks for software such as application themes, skins and personas. The use of our Marks on websites is discussed below.
You may use the Word Marks and the Logos in themes, personas, or skins for applications to show your support for Zcash, provided that the use is non-commercial and the use is clearly decorative, as contrasted with a use that appears to be the branding for a website or application.
We will likely consider using the Marks in a software distribution that combines our software with any other software program an infringement of our Marks. We would consider your software “combined” with ours if you create a single executable for both software programs, as well as if by installing our software it automatically installs yours. We would not consider your software “combined” with ours if it is on the same media but requires separate, independent action to install it.
See Universal considerations for all uses, above, which also apply.
You may use the Word Marks and Logos, but not the Trade Dress, on your webpage or social media bio to show your support for Zcash as long as:
You can use the Word Marks in book and article titles, and the Logo in illustrations within the document, as long as the use does not suggest that we have published, endorse, or agree with your work.
You can use the Word Marks as part of your user group or meetup name provided that:
Note that the Universal considerations for all uses, above, still apply, specifically, that you may not use or register the Marks as part of your own trademark, service mark, domain name, company name, trade name, product name or service name.
“Promotional goods” are non-software goods that use the Marks and that are intended to advertise Zcash, promote Zcash, or show membership in the Zcash community.
You may make promotional goods for free giveaways.
We will likely consider using the Marks as part of a domain name or subdomain an infringement of our Marks. We would likely consider using the Marks on promotional goods for sale an infringement of our Marks.
The first or most prominent mention of a Mark on a webpage, document, packaging, or documentation should be accompanied by a symbol indicating whether the mark is a registered trademark (“®”) or an unregistered trademark (“TM”). See our Trademark List for the correct symbol to use.
Also, if you are using our Marks in a way described in the section “Uses for which we are granting a license,” please put following notice at the foot of the page where you have used the Mark (or, if in a book, on the credits page), on any packaging or labeling, and on advertising or marketing materials: “Zcash is a trademark of the Zcash Foundation. Used with permission from the Zcash Foundation.”

If you have any questions about this Policy, would like to speak with us about the use of our Marks in ways not described in the Policy, or see any abuse of our Marks, please email firstname.lastname@example.org.
The Foundation reserves the right to modify this Trademark Policy at any time. You should review this Trademark Policy from time to time so that you will be aware of any updates. Any updates will apply as soon as they are posted on this page.
