⚠️ Relevant Note ⚠️

We are excited to announce that we have created a new package called izari-filecoin 🔗, which will be the successor to filecoin-signing-tools. Izari Filecoin is an advanced and user-friendly package that includes several new features and improvements that were not available in this project. The new package is also better organized and easier to use. While this project will continue to be maintained, no new features will be added to it. Therefore, we strongly recommend that you switch to Izari Filecoin to take advantage of its new features and benefits.
