ERC721SignatureMint

import "@thirdweb-dev/contracts/base/ERC721SignatureMint.sol";

The ERC721SignatureMint smart contract uses the ERC721Base base contract along with the SignatureMintERC721 contract extension.

Signature minting uses the EIP-712 standard, enables a contract admin to authorize an external party's request to mint tokens on the admin's contract. At a high level, this means you can authorize another wallet to mint tokens on your contract, and specify what exactly will be minted by that external party.
