ERC-6220 This was a popular Ethereum protocol that came out three years ago during the peak of GameFi, specifically designed for GameFi. Simply put, all equipment is NFT. A set of equipment can be combined onto a game character, turning it into a composite NFT. I gave a lecture about this protocol a few years ago. I guess what Katana means is that you complete various tasks to earn equipment, then assemble them onto the main NFT character. And it’s related to airdrops. @katana is truly hardcore... A project launched without VC backing is just so bold, no need to worry about whether those clueless VCs can understand it.
