ERC721 Lazy Mint

ERC721LazyMint allows you to lazy-mint ERC-721 tokens, and by default allows any wallet to claim a lazy-minted NFT. It exposes a verifyClaim function that you can override to add your claim-restriction logic.

Lazy minting allows you to define the metadata of NFTs without minting it to an address. As a contract admin, this lets you prepare the metadata for NFTs that will be minted by other wallets, without paying the gas cost for actually minting the NFTs.
