The sale of NFTs raises significant copyright concerns. Artists must be cautious about tokenizing copyrighted materials without proper authorization from the original creators or copyright holders. Even if an artist created the digital artwork, it's crucial to verify whether it incorporates copyrighted elements or brands. Failure to respect copyright laws may lead to legal repercussions, takedowns, or disputes with copyright owners. It's advisable to create original content or obtain proper licensing to avoid copyright infringement issues.
