UUPS Upgradeable
Last updated
Last updated
An upgradeability mechanism designed for UUPS proxies. The functions included here can perform an upgrade of an {ERC1967Proxy}, when this contract is set as the implementation behind such a proxy. A security mechanism ensures that an upgrade does not turn off upgradeability accidentally, although this risk is reinstated if the upgrade retains upgradeability but removes the security mechanism, e.g. by replacing UUPSUpgradeable with a custom implementation of upgrades. The {_authorizeUpgrade} function must be overridden to include access restriction to the upgrade mechanism. Available since v4.1.
Upgrade the implementation of the proxy to newImplementation. Calls {_authorizeUpgrade}. Emits an {Upgraded} event.
