🪟 Adminable Proxy

Introduction

The Adminable Proxy is a simple ERC-1967 proxy that is designed to be managed by an admin. The admin can upgrade the proxy and get it's latest implementation.

Implementation

The AdminableProxy is very similar to OZ's TransparentProxy except that the proxy admin is not deployed everytime in the constructor. Users can freely pass their own Admin contract address.

import "@openzeppelin/contracts/proxy/ERC1967/ERC1967Proxy.sol";

contract AdminableProxy is ERC1967Proxy {
    address private immutable _ADMIN;

    constructor(
        address logic_,
        address admin_, // can be arbitrary
        bytes memory data_
    ) payable ERC1967Proxy(logic_, data_) {
        _ADMIN = admin_;
        ERC1967Utils.changeAdmin(admin_);
    }

    . . .
