# ITransparentUpgradeableProxy

[Git Source](https://github.com/Ion-Protocol/ion-protocol/blob/88cc595825f1dc2eb738fb93e172a3e8ab7a5c43/src/admin/TransparentUpgradeableProxy.sol)

Copy of OpenZeppelin's `TransparentUpgradeableProxy` that uses alternative `ProxyAdmin`

*Interface for {TransparentUpgradeableProxy}. In order to implement transparency, {TransparentUpgradeableProxy} does not implement this interface directly, and its upgradeability mechanism is implemented by an internal dispatch mechanism. The compiler is unaware that these functions are implemented by {TransparentUpgradeableProxy} and will not include them in the ABI so this interface must be used to interact with it.*
