1234567891011121314151617181920212223242526// SPDX-License-Identifier: MITpragma solidity ^0.7.0;import "../openzeppelin/proxy/UpgradeableProxy.sol";/*** @dev This contract implements a proxy that is upgradeable by an admin.** To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector* clashing], which can potentially be used in an attack, this contract uses the* https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. 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 one of the admin functions exposed by the proxy itself.* 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the* implementation. If the admin tries to call a function on the implementation it will fail with an error that says* "admin cannot fallback to proxy target".** These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing* the admin, 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.** Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way,* you should think of the `ProxyAdmin` instance as the real administrative inerface of your proxy.*/
