function pause() external nonpayable

PAUSABLE

paused

function paused() external view returns (bool)

Returns true if the contract is paused, and false otherwise.

Returns

NameTypeDescription
_0boolundefined

proxiableUUID

function proxiableUUID() external view returns (bytes32)

Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade. IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the notDelegated modifier.

Returns

NameTypeDescription
_0bytes32undefined

TRANSFER RESTRICTIONS

Parameters

NameTypeDescription
tokenIDuint256undefined

Returns

NameTypeDescription
_0stringundefined

renounceOwnership
