        bytes memory bytecode = abi.encodePacked(type(DeBridgeTokenProxy).creationCode, constructorArgs);

        assembly {
            deBridgeTokenAddress := create2(0, add(bytecode, 0x20), mload(bytecode), salt)

Additional Details

Hello,

Trying to deploy contract using the CREATE2 OP Code as specified in the snippet but the contract reverts the entire transaction.

I think it may be related on how zksync stores and uses contract code but I dont have any clue how to overcome this limitation.

Do you have any insights?

[bxpana]

It might be failing if the compiler doesn't know the bytecode for the contract ahead of time. is abi.encodePacked(type(DeBridgeTokenProxy).creationCode absolutely necessary? Otherwise I would try like we have in the example in the docs and do type(DeBridgeTokenProxy).creationCode

Hi @bxpana

You are correct, since era does not store deploymentCode but only a hash of it, we need to store the deploymentCode of the aforementioned DeBridgeTokenProxy, either by deploying it explicitly, or by registering it in the L1.

Do you know how to register the bytecode?

[popzxc]

As long as factory bytecode is being sent together with deployment tx (happens automatically when using hardhat/foundry), you don't need to manually register any bytecode.

[popzxc]

I think that the issue stems from the fact that constructor parameters are passed differently from L1, so abi.encodePacked doesn't work as intended here.

Could you try deploying it using salted syntax? e.g.

DeBridgeTokenProxy deBridgeTokenProxy = new DeBridgeTokenProxy{salt: salt}(<constructorArgs>);

I will mark the question as answered; feel free to un-answer if you have any follow-ups.
