@ -11,7 +11,7 @@ Most of the proxies below are built on an abstract base contract.
In order to avoid clashes with the storage variables of the implementation contract behind a proxy, we use https://eips.ethereum.org/EIPS/eip-1967[EIP1967] storage slots.
- {ERC1967Upgrade}: Internal functions to get and set the storage slots defined in EIP1967.
- {ERC1967Utils}: Internal functions to get and set the storage slots defined in EIP1967.
- {ERC1967Proxy}: A proxy using EIP1967 storage slots. Not upgradeable by default.
There are two alternative ways to add upgradeability to an ERC1967 proxy. Their differences are explained below in <<transparent-vs-uups>>.
