The ERC20SignatureMintVote smart contract adds signature-based minting extension to the ERC20Vote base contract. It also implements the ERC20Votes contract, which provides voting and delegation functionality, along with delegation by signature. Signature minting uses EIP-712, which enables the 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 others to mint tokens on your contract, and specify what exactly will be minted by that external party.
