Hi everyone, I trust everyone is well. I’ve been studying the proxy contracts to get a better understanding of how they work. I’ve come across a few things that I don’t understand along the way. I’ve listed some questions below. The BaseAdminUpgradeabilityProxy contract inherits the BaseUpgradea…

Hi @cjd9s , You may want to look at the proxy contracts that were migrated to OpenZeppelin Contracts 3.x which could be simpler to follow the hierarchy: OpenZeppelin/openzeppelin-contracts/blob/v3.2.0/contracts/proxy/TransparentUpgradeableProxy.sol // SPDX-License-Identifier: MIT pr…

Hi @cjd9s , Let me know if you need more information.

Hi Andrew @abcoathup , If you ever stop hearing from me, it’s because I’m dead. I will never not need more information. I prefer to download and inherit the proxy contracts directly.

Hi Andrew @abcoathup , The link for the issue that I created is https://github.com/ethereum/solidity/issues/10131 . Cheers. Sincerely, Craig

Hi @cjd9s , In case you didn’t know, in GitHub you can use Markdown to improve the readability of your post. It may be worth adding this to your contract examples to make your Issue easier to read ```solidity Code goes here ``` You can also add a quote for the line from the documentation. > Qu…

Hi Andrew, I didn’t know that. I have used your suggestions to clean up the issue. Cheers. Sincerely, Craig
