What are Soulbound NFTs?

Picture a medal you've earned in a marathon. It's special, unique, and inextricably tied to your identity. Enter the world of Soulbound NFTs. As a significant part of Modular NFTs, these unique digital assets, like your marathon medal, are 'soulbound' to a specific blockchain address or another NFT, making them a permanent and personal part of the digital universe.
Take the case of a unique digital creature, a Kanaria, in the metaverse. It can possess gems that are Soulbound NFTs. These gems, while enhancing the value of the Kanaria, cannot be removed or transferred. They're there for good, bringing a new layer of permanence to the NFT world.
