After running into a Diamond contract last night I was looking for a better understanding of upgradable contracts. Thanks for always putting out relative content in a space that is continually growing and changing. Every time I think I know a good bit about smart contracts and solidity something new throws me for a loop but you always seem to have an easy to understand video ready for me to watch on the subject.

[@PatrickAlphaC]

Glad you like it! Yeah I've recently updated my opinion on diamonds too (although, I STILL think the name is absolute trash, which I have expressed. I prefer something like "multi-implementation proxy" or something... or something).

[@clydedavidson9272]

@@PatrickAlphaC I really only started looking into them as I am hoping to break into auditing and it seems a ton of companies/devs are implementing all these upgrade patterns into their flow. Figured I better familiarize myself with them now.

[@clydedavidson9272]

@@PatrickAlphaC Do you ever plan on doing a diamond tutorial. I understand they essentially have multiple implementation contracts (facets) but am a bit confused on diamond storage or app storage allowing us to store state variables at predetermined positions using a hash. Would be amazing to see you break down the standard!

[@cs1070151]

Proxy contract is popularly known as PIMPL (pointer to implementation) in languages like C++ to keep the ABI same, but of course the whole mechanism of 'delegateCall' (in which you are touching data in the calling contract) makes this a completely novelty.

[@PatrickAlphaC]

Yeah, delegatecall is hero mode

[@bezimienny5]

Oh, my first thought for a solution would be something like what you showed as proxy. I mean, I only really gave it a small amount of thought with the limited beginner understanding of Solidity that I have, so the fact that I came up with that much still makes me feel smart 😊

[@RodNavarroYtb]

So, Diamond is like microservices for smart contracts. Cool video Patrick. Trying to get into this stuff. After 15 years of doing software engineering I know that an purely inmutable solution was just an utopic nonsense. Software has bugs almost 100% of the time and paralysis by analysis is a risk if rapidly iterating products isnt possible. Let alone building a real business case

[@PatrickAlphaC]

There is a little give and take on this. Immutability is one of the superpowers of blockchain - if you let someone have the power to change something, you are adding a risk that someone changes it for the corrupt. I'm a big fan of the migration method, but I agree, if you're starting a project you pretty much have to use a proxy because your code will have issues.

[@RodNavarroYtb]

@@PatrickAlphaC yeah. Bugs will always be part of software engineering. Even if you code a million unit testings. I’ve ever seen a platform that’s bug free. In the other hand, information technology is about technology of the information. Software has to be written by somebody. Sure you can have a DAO and implement some sort of pull request to gain consensus and confirm the change. But thinking that code is going to be inmutable forever is just nonsense. Code get obsolete by the minute. A common case are security patches because of dependencies…

[@PatrickAlphaC]

@@RodNavarroYtb Maybe. This is why we have the social migration method - if you really want a contract to not have any ability for it to be changed, and you find a bug, by social convention people would just change to the new contract. But yes, agreed, having zero bugs is sort of insane.

[@PepperFiend57]

You're awesome man! Was just about to look into this yesterday right as you dropped the vid. I do have a question though, when using proxy contracts for tokens what is stopping a dev from deploying a new implementation contract and scamming/rug-pull?

[@PatrickAlphaC]

Glad you liked it! And the answer is.... nothing is. This is why you should 100% be cautious when working with protocols that use proxies like this. A lot of ERC20s don’t have proxies, which is good, since that means they can’t upgrade without social YEETing the old contract

[@PepperFiend57]

@@PatrickAlphaC Thanks for the quick reply! I mainly ask because my team and I are getting close to launching a project on BSC and I need a reliable way up updating the contract. The social YEET just seems like too much work😂 I like the proxy concept a lot, but worry about the investor perspective

[@PatrickAlphaC]

@@PepperFiend57 if you give the admin key to a governance protocol, that might be the best. Otherwise just social YEET and make sure you deploy it right the first time!

100% They have some great tutorials to do so as well

[@TheDoktorot]

Thanks for the tutorial, it was really helpful. Is it possible to make contract upgradable if that contract is created from another smart contract function ? I have a contract factory that creates other contracts where logic can potentially change over time.

[@chunter]

Why did functions burn(uint256) and collate_propagate_storage(bytes16) have the same function selector? Was this just a genuine hash collision or something deeper?

Can you also explain how we handle calls when we have onlyOwner modifier applied to some functions. They fail as it is not our account calling them but proxy contract

[@PatrickAlphaC]

This is the difference between delegate call and call. Could you ask this on stack exchange ETH or peeranha actually? I'd like others to be able to see the answer.

do you know how to do it? I'd like to know how to do it too!

[@RonaldoGuedes]

So, is it possible upgrade my contract and fix some issues? and then add a function to withdraw/burn tokens storage in the contract? I have lots of tokens stucked there. My addLiquidity function is filling up de contract with tokens. Is there a way to fix that?

[@PatrickAlphaC]

If it was deployed with upgradeability, yes. Otherwise you’ll have to use the yeet method

[@RonaldoGuedes]

@@PatrickAlphaC no, it's not deployed with this method. So is it impossible, right?

If you added upgradeability, you can just follow this video, otherwise you’ll have to redeploy or just give out 50% of your tokens

[@J3-2344]

is this applicable to the erc20 token tutorial you've made a little bit ago? is it upgradable? thanks in advance

[@PatrickAlphaC]

Every contract is! You just need to use a proxy like demonstrated. I used brownie instead of hardhat in that demo, but you can use hardhat for erc20s no problem

@@PatrickAlphaC thanks 🙏

[@veliea5160]

can we implement proxy contracts with factory pattern. factory contract will create upgradeable smart contracts

[@PatrickAlphaC]

You sure can

[@hq3d-printing]

Rather than an admin changing the implemented contract a proxy points to, is it possible to require a specified % of users, like 51%, to vote for the change in order for it to happen?

[@PatrickAlphaC]

Oh my friend. I have a video coming out just for you. We are doing a DAO workshop at the Chainlink hackathon that will give you 95% of the answer

[@jordixboy]

So, if the state is stored on the proxy, and the proxy calls the implementation, and the implementation does perfom some logic before writing changes/additions to a state variable, how does that exactly work? How does the proxy know, he can add that change/addition to the state?

[@PatrickAlphaC]

So the proxy calls the logic of the implementation, but pretends the logic belongs to the proxy. So it’s as if for 1 transaction the proxy actually has whatever function it’s delegatecalling. Does that make sense?

[@jordixboy]

@@PatrickAlphaC So, the proxy copies the implementation logic to the proxy? Not sure im understanding this

[@PatrickAlphaC]

Spot on!

I have big question , After deploy the contract , where you upgrade it ? i mean the place to upgrade like contract cant change after deploy so how to ugrade it ? You show us the functions but you didnt show us how and where ? Like if you can do video after deploy , you upgrade it , please bro

[@PatrickAlphaC]

I have some scripts in the repo called “upgrade” that you call to upgrade. The proxy address always stays the same - so you use that contract
