Brand Policy

Welcome to the Brand Policy (“Policy”) of the Stellar Development Foundation (the “SDF”, “we”, or “us”).


This Policy describes the conditions under which any licensee (“you”) may use SDF’s wordmarks, logos, and similar intellectual property (the “Brand Assets”). By using or reproducing a Brand Asset you are agreeing to abide by this Policy that forms a binding agreement between you and SDF. If you are using a Brand Asset on behalf of a legal entity such as your employer, you represent that you have the authority to bind such entity, and the terms “you” or “your” shall include such entity. This policy may be updated by SDF at its discretion from time to time.

The goal of this Policy is to promote the legitimate use of, and protect the integrity of, the Brand Assets. At the same time this Policy aims at preventing brand confusion in order to protect the community from scammers who might use the Brand Assets to steal, defraud or mislead. If you would like to use any of the Brand Assets in a manner that is not expressly permitted by this Policy, please contact us directly at [email protected].

B. Forked Software

Stellar software is provided on a free and open-source basis, and all Stellar source code is governed by the Apache 2.0 license.
