Fail - Unable to verify.

[Hashflower]

Describe the bug

Ive used your tool for some time now, but suddenly im unable to verify any contracts with it. Im compiling, deploying, trying to verify as usual (with the same build folder), however the error keeps coming : Fail - Unable to verify. Compiled contract deployment bytecode does NOT match the transaction deployment bytecode. Are there some incompatibility I'm not seeing ? Do I need to flatten the contract manually then pass it to verify ?

Steps To Reproduce

truffle run verify [CONTRACT1 CONTRACT 2...] --network arbitrum

I have the exact same problem. Did you find a fix yet? The sourcify verification is working for me

[rkalis]

It's very hard to debug these kinds of issues.

@Hashflower could you run it using the latest version of the plugin since you state that you're using v0.6.1, but the debug log output shows v0.5.11?

@sebastian-baier If sourcify verification does work it's possible that there's something weird on Etherscan's side 🤔

[Hashflower]

It seems that the issue happens with imports, esp with open zeppelin. I managed to verify once deployed flattened.

[sebastian-baier]

@rkalis hmm yes it's really strange, especially because I verified the same contract last week (I think), without updating inbetween here my output (it says Successfully verified 1 contract(s).):

@Hashflower happy to hear that you managed to verify it in the end. Your debug output shows that you're using version 0.5.11 of the plugin, which was released 2+ years ago. Since that time several bugs have been fixed, so I wouldn't be surprised if one of those fixes also fixes your issue if you switch to the latest version.

[rkalis]

@sebastian-baier especially if that's the case, I'd think that the issue might be on Etherscan's side. Let me see if I can summon @Enigmatic331 to see if he knows what's up.

[Hashflower]

@rkalis i actually tried many many versions including the latest, with the same result. Sourcify was working tho. The only way I made it work was to deploy a flattened version and then verify. Imports won't let me verify it.

[rkalis]

@Hashflower hmm yeah in that case it might be related to something on Etherscan's side if the verification does work on Sourcify

[sebastian-baier]

It works now again with the same contract ^^ @rkalis seems like there really was a problem with etherscan

[rkalis]

Thanks for letting me know. I guess we can chalk it up to an ephemeral issue with Etherscan that has been resolved now. If it persists we can re-open the issue.
