Author very kindly made the plugin free & open source software after a quick PM. 5/5 stars for this resource. :)

Thanks for creating this wonderful plugin, my players are always playing with things as if they were NFT, now it will be possible thanks to your plugin! I hope it stays simple and always being updated for new versions :)

Very good resource, works out of the box and our players love it to keep their creations unique.

Been looking for a plugin like this for ages! Always been baffled by the fact that no one has released one.
About time you shared this with others, Jann! :,D
