❔ How to Use CreateX on Abstract?

[geauser]

I'm having trouble deploying contracts with CreateX on Abstract. I get a FailedContractCreation error when trying to deploy using bytecode in .data from ethers factory.getDeployTransaction(). I assume it's something related to the quirks of ZkSync but I can't figure it out for now.

Hey there! coffee from the Abstract team here - can you provide a little more details about what you are trying to deploy and if its possible that the contract deployment itself is reverting in the constructor? In general CreateX should work the same as on other chains as it is deployed as an EVM contract and not in zksync/EraVM mode.

Hello @coffeexcoin !

So basically I have this piece of code relying on ethers@6:

  const createX  = await hre.ethers.getContractAt(createXAbi as unknown as any[], createXAddress, deployer);
  const initCode = await factory.getDeployTransaction(...constructorArgs);
  const { salt, guardedSalt } = await computeCreate3Salts(contractName, deployer);
  const address = await computeCreate3Address(guardedSalt);
  const tx = await createX.deployCreate3(salt, initCode.data) as TransactionResponse;
  const receipt = await tx.wait();

And with it I deploy a ERC1967 proxy for UUPS upgradability using @matterlabs/hardhat-zksync internal functions to get factory/artifact but it doesn't work (Im using internal functions because @matterlabs/hardhat-zksync-upgradable doesn't support custom deploy functions). I'm not even sure that the issue comes from my usage of deployCreate3 because on other regular chains it works just fine.

You use the wrong EVM initcode for Abstract. Do not use EraEVM compiled code with CreateX. You must use the same EVM initcode as on Base:

Please forget about all the ZKsync-specific stuff for a moment and deploy to Abstract as you would do to any other EVM-compatible chain.

@pcaversaccio Finally back at the computer! I tried sending EVM (not EraEVM) bytecode and still the same issue https://abscan.org/tx/0x4a566083410c224cde9dde64a06719e182376450a2b1d9a3d0d019f450bb3fa4 the only thing different from the base deploy is the implementation address.

[geauser]

@pcaversaccio Also just did an attempt at manually deploying using Base transaction data to no avail https://abscan.org/tx/0xca4e76babacb93303622a8eeac7d9706e23f938bafeff02ab03955ac8ced56e9

[coffeexcoin]

Is your implementation on Abstract also deployed as EVM (not EraVM)?

You cannot delegatecall between EVM and EraVM contracts

[geauser]

@coffeexcoin Aaah that's a good point, the implementation is indeed deployed as EraVM so it could be the issue indeed. So I would need to deploy regular EVM bytecode as well for the implementation right? Is it even possible on Abstract, really not familiar with ZkSync.

[coffeexcoin]

Correct. Would recommend reading thru the EVM interpreter docs here: https://docs.zksync.io/zksync-protocol/evm-interpreter/overview
