Thanks to OpenSats and its generous donors, Damus has been able to continue building open source freedom tech without influence from external parties. Damus' mission is to build the best nostr and bitcoin tech without compromise on decentralization, and this will continue to be our mission going forward. This wouldn't be possible without OpenSats and other organizations that continue to help make this vision a reality!

As per our OpenSats agreement, we are required to publish quarterly reports on our progress. We submit this report to nostr for full transparency. If you're curious what we've been working on this past quarter, check it out:
