This pattern implies two * things that go hand in hand: * * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if * that call matches the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself. * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating * the proxy admin cannot fallback to the target implementation. * * These properties mean that the admin account can only be used for upgrading the proxy, so it's best if it's a * dedicated account that is not used for anything else. This will avoid headaches due to sudden errors when trying to * call a function from the proxy implementation. For this reason, the proxy deploys an instance of {ProxyAdmin} and * allows upgrades only if they come through it. You should think of the `ProxyAdmin` instance as the administrative * interface of the proxy, including the ability to change who can trigger upgrades by transferring ownership. * * NOTE: The real interface of this proxy is that defined in `ITransparentUpgradeableProxy`. This contract does not * inherit from that interface, and instead `upgradeToAndCall` is implicitly implemented using a custom dispatch * mechanism in `_fallback`. Consequently, the compiler will not produce an ABI for this contract. This is necessary to * fully implement transparency without decoding reverts caused by selector clashes between the proxy and the * implementation. * * NOTE: This proxy does not inherit from {Context} deliberately. The {ProxyAdmin} of this contract won't send a * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract. * * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an * undesirable state where the admin slot is different from the actual admin. Relying on the value of the admin slot * is generally fine if the implementation is trusted. * * WARNING: It is not recommended to extend this contract to add additional external functions. If you do so, the * compiler will not check that there are no selector conflicts, due to the note above. A selector clash between any new * function and the functions declared in {ITransparentUpgradeableProxy} will be resolved in favor of the new one.
