TransparentUpgradeableProxy

Inherits: ERC1967Proxy

Functions

constructor

Initializes an upgradeable proxy managed by _admin, backed by the implementation at _logic, and optionally initialized with _data as explained in {ERC1967Proxy-constructor}.

constructor(address _logic, address admin_, bytes memory _data) payable ERC1967Proxy(_logic, _data);

ifAdmin

Modifier used internally that will delegate the call to the implementation unless the sender is the admin.

modifier ifAdmin();

Returns the current admin. NOTE: Only the admin can call this function. See {ProxyAdmin-getProxyAdmin}. TIP: To get this value clients can read directly from the storage slot shown below (specified by EIP1967) using the https://eth.wiki/json-rpc/API#eth_getstorageat[eth_getStorageAt] RPC call. 0xb53127684a568b3173ae13b9f8a6016e243e63b6e8ee1178d6a717850b5d6103

function admin() external ifAdmin returns (address admin_);

implementation

Returns the current implementation. NOTE: Only the admin can call this function. See {ProxyAdmin-getProxyImplementation}. TIP: To get this value clients can read directly from the storage slot shown below (specified by EIP1967) using the https://eth.wiki/json-rpc/API#eth_getstorageat[eth_getStorageAt] RPC call. 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc

function implementation() external ifAdmin returns (address implementation_);

changeAdmin

Changes the admin of the proxy. Emits an {AdminChanged} event. NOTE: Only the admin can call this function. See {ProxyAdmin-changeProxyAdmin}.

function changeAdmin(address newAdmin) external virtual ifAdmin;

upgradeTo

Upgrade the implementation of the proxy. NOTE: Only the admin can call this function. See {ProxyAdmin-upgrade}.

function upgradeTo(address newImplementation) external virtual ifAdmin;

upgradeToAndCall

Upgrade the implementation of the proxy, and then call a function from the new implementation as specified by data, which should be an encoded function call. This is useful to initialize new storage variables in the proxied contract. NOTE: Only the admin can call this function. See {ProxyAdmin-upgradeAndCall}.

function upgradeToAndCall(address newImplementation, bytes calldata data) external payable virtual ifAdmin;

_beforeFallback

Makes sure the admin cannot access the fallback function. See {Proxy-_beforeFallback}.

function _beforeFallback() internal virtual override;
