GemCave DIG is our custom NFT smart contract written from the ground up to be 100% on-chain and 100% secured like no other NFT. GemCave NFTs are not only stored on-chain as base64 encoded SVG, but they are also randomly generated, rendered and minted 100% on-chain too meaning we are the FIRST NFT to not require any external server or service to process, store or generate NFTs, and we have the built in security and provability of the blockchain! They live securely, forever on the blockchain.
