ERC-721 Drop

The ERC721Drop smart contract uses the ERC721SignatureMint base contract along with the LazyMint, DelayedReveal and DropSinglePhase contract extension.

The drop mechanism in the DropSinglePhase extension is a distribution mechanism for lazy minted tokens. It lets you set restrictions such as a price to charge, an allowlist etc. when an address attempts to mint lazy minted tokens.

The ERC721Drop contract lets you lazy mint tokens, and distribute those lazy minted tokens via signature minting, or via the drop mechanism.
