Greetings. I would like to understand how I can upgrade a contract that was deployed from another contract. vault.logic = new CompoundVault(); <--- stores implementation address of upgradeable vault.logic.initializeIt( address(this), deployer, cToken…

We don't have a ProxyFactory contract for Solidity 0.8 but you can take a look at this one that a user built recently: [image] Deploying Upgradeable Proxies and Proxy Admin from Factory contract Upgrades @frangio Here is my initial attempt. Please let me know if its in th…

Hello @Skyge ! I am using "@openzeppelin/contracts-upgradeable": "^4.0.0", "@openzeppelin/hardhat-upgrades": "^1.6.0", There is 2 thing I don't get. I deploy my main contract. This contract deploys other contract. I store the contract in a library (struct). But I don't know what is the address…

In Solidity, unless you explicit deploy a Proxy contract, your contracts will not be upgradeable. This is why you're only seeing implementation addresses. If you want to deploy upgradeable contracts, you will have to import a proxy contract from OpenZeppelin Contracts and deploy it using new as wel…

Humm ok that is a bit confusing! First my contract (CompoundVault) is already upgradeable when I use hardhat to deploy. But I deploy it from my main contract. I'm not sure I understand. I have to pass the address of CompVault to the proxy? so already deployed? but deployed with the proxy? Which …

Have you read this tutorial? I think it can give you some idea. OpenZeppelin Upgrades: Step by Step Tutorial for Hardhat - General / Guides and Tutorials - OpenZeppelin Community

Yes this is my procedure for all my contract. But im unable to do it like that because it's not the hardhat plugin that is deploying my contract. It's a contract. import ".CompoundVault.sol" <---- is upgradeable import "./lib/CVault.sol"; <---- struct Lib where…

I found this! OpenZeppelin/openzeppelin-sdk/blob/master/packages/lib/contracts/upgradeability/ProxyFactory.sol pragma solidity ^0.5.3; import "./InitializableAdminUpgradeabilityProxy.sol"; import "../cryptography/ECDSA.sol"; contract ProxyFactory { event ProxyCreated(address pr…

This look like what I want! Reading trough! Thank you @frangio And @Skyge

I forgot to mention, do note that the code I linked is using UUPS proxies. For transparent proxies you will need to use TransparentUpgradeableProxy rather than ERC1967Proxy, and refer to its documentation, particularly the constructor parameters.

I tried with UUPS //SPDX-License-Identifier: Unlicense pragma solidity ^0.8.2; import "@openzeppelin/contracts-upgradeable/proxy/utils/Initializable.sol"; import "@openzeppelin/contracts-upgradeable/proxy/utils/UUPSUpgradeable.sol"; import "@openzeppelin/contracts-upgradeable/access/OwnableUpgrade…
