Hi Raul,
Greetings from Syncfusion support.
Currently, We do not have support for EJ2 Signature component on blazor platform, but we have logged the requirement as a feature, and it can be tracked via our feedback portal.
To make it count, please cast your vote. We will prioritize the features based on the demands of each release If you have more specifications / suggestions on the request for the feature, you can add it to the portal as a comment.
Thanks,
Sureshkumar P
