The OpenSea Collection Manager allows creators to make NFTs without any upfront gas cost, as the NFT isn’t transferred on-chain until the first purchase or transfer is made.
NFTs made with the Collection Manager follow the ERC-1155 standard, partly to help with gas-free minting and partly to help us add exciting features in the near future.
For more information on lazy minting, check out this helpful resource created by our co-founder, Alex!
