Roadmap

Tallywallet’s mission is to provide a validated Pythonic framework for money trading and economic applications.

It is developed by a private individual but released to the public under the GNU Affero General Public License.

The API may change significantly as the project proceeds. At this early stage, you should only use the latest release, which may not be compatible with previous versions.
