ERC721PausableUpgradeable

Inherits: Initializable, ERC721Upgradeable, PausableUpgradeable

ERC-721 token with pausable token transfers, minting and burning. Useful for scenarios such as preventing trades until the end of an evaluation period, or having an emergency switch for freezing all token transfers in the event of a large bug. IMPORTANT: This contract does not include public pause and unpause functions. In addition to inheriting this contract, you must define both functions, invoking the Pausable-_pause and {Pausable-_unpause} internal functions, with appropriate access control, e.g. using {AccessControl} or {Ownable}. Not doing so will make the contract pause mechanism of the contract unreachable, and thus unusable.
