Contract Code

Does this work on other EVMs? (If yes, please list at least 1 of them)

Ethereum, OPStack, Scroll, Polygon

Description of What Your Contract Does

I have an Account Factory that deploys a UUPS Proxy account and its proxy in a single transaction as part of a smart contract. The create code provided in the documentation (using yul) does not produce an address that has a code length after return.

It seems as if the lifecycle of the bytecode is different for zkSync, as deploying the ERC1967 proxy fails to deploy due to the given address not being a contract (code.length == 0).

Additional Details

The code length at the address after the create yul is empty.

Hey hey @scotthconner 👋

I can't recall where we left off in Austin re this issue but if you are still facing the issue please refer to the @hardhat-zksync-upgradable documentation that discusses UUPS upgradability here.

[scotthconner]

I successfully use that just fine. The issue is deploying an implementation contract from within a factory results in a zero code length for the resulting address.

The behavior is divergent from other EVMs. This is happening within the VM, and not during deployment from a client using the utility.

Is there a solidity example of deploying UUPS proxies?

[dutterbutter]

There is no working example currently but we will create one and share with the community. That is a great suggestion.

Hi @scotthconner, we have an example that deploys a Beacon proxy on our code. Let me know if this helps your case.
