From https://www.taler.net/de/news/2024-03.html:
As part of NGI TALER, NLnet Foundation is running an open call and will award grants to third parties working on GNU Taler enhancements globally . The application process is simple and the first submission deadline is April 1st 2024.
Taler works with tokens for paynents. To me, they feel like capabilities for money. Can Spritely interface with GNU Taler? There are still a few days left to apply for a grant!
