# Onchain Technology

The team have opted to take an “On-Chain” minting technology approach for the NFT collection in which unlike off-chain, where NFTs  are stored outside the blockchain, on-chain NFTs are NFTs where all data used to create the image is stored inside the smart contract on the blockchain instead of storing just a url that points to an image stored somewhere else that can be taken down at any time. 

Off-chain NFT data is usually stored outside the blockchain in places such as on the cloud, centralized hardware server storage, or IPFS.
