Issue Signing on Optimism

[pvdyck]

Signing this optimism transaction hangs just after the scan. Nothing happens ...

[AndreasGassmann]

Hi. Could you let us know which version of the Vault you are using? Earlier versions of the Vault used to have problems with Optimism, but that should be fixed in the latest version.

[pvdyck]

Latest (3.28.0) Previously, when I had an issue with Optimism signing, I received a message saying so Now, the screen goes black after the QR scan and stays stuck there

[pvdyck]

@AndreasGassmann Were you able to reproduce ? It's a transaction exiting a beefy vault => https://app.beefy.finance/vault/velodrome-lusd-dai

[pvdyck]

@airgap-it any help here ?

[pvdyck]

Issue still there with latest release please HELP !

Hey @pvdyck I am sorry we couln't help yet. Can you tell us the exact setup you're using? I can't identify where the screenshot you posted is coming from. Is that Metamask + Airgap Vault?

[pvdyck]

@mlaeng Rabby chrome extension, how can I help you better to find out the exact issue? Thanks

[mlaeng]

@pvdyck In the meantime I was able to find out what your setup is. I got the Rabby extension and did setup one of my Optimism accounts from my Airgap vault to be used with it. I was able to deposit in this vault and then to withdraw from it:

https://app.beefy.finance/vault/velodrome-v2-op-velo

(The vault you were using doesn't allow deposits anymore, so I've chosen a similar one with Velodrome LP tokens)

Rabby did show me the QR code which I did scan with my AirGap Vault, then signed the tx in order to see the new QR on my AirGap vault and then scanned this from the Rabby wallet. Worked just fine.

And could easily sign using AirGap vault. I am using 3.29.0 (build 53670) on Android. Not sure what you are doing differently. May i ask what device you are using?

[mlaeng]

Not sure yet, on which step it fails for you. You say that after you scan the QR code that is displayed by Rabby, with your AirGap vault, the screen turns black instead of showing you a "Sign Transaction" screen with the transaction details?

[pvdyck]

Android - Motorola , all software updates installed (including the webview) / Airplane mode / Not using any other app on the phone Using Moto e7(i) Power / Android 10 Airgap-Vault latest version

@pvdyck does it look like this after scanning the Qr code?

[pvdyck]

yes, exactly, black screen !

[mlaeng]

Well, not completely black... Bizarre. I got the same when I scanned the QR code which you posted above. But If I scanned the Qr code that was displayed for me it worked without a problem... It is also the case that now I need to exit the AirGap Vault completely in order to get the camera again. I need to check something.

[pvdyck]

Great, as long as you can reproduce it ... The problem is half solved 😉

[mlaeng]

Do you have more than one account synced with Rabby?

[mlaeng]

@pvdyck I was able to reproduce the complete scenario with the same result

1. I connected my account into rabby via "connect hardware wallets" and syncing from airgap vault. Rabby now shows my address 0xSomething
2. everything works, I could sign from my airgap vault via QR code exchange
3. now I deleted the secret I derived that account from from my AirGap Vault
4. Rabby now still shows the account but if I try to create a transaction now and scan it with the vault I end up with the same black screen as you, because the vault does not have the secret anymore. same black display, same behaviour.

So my suspicion is that your AirGap Vault does not have the secret anymore which the account (the one which is connected in Rabby) was derived from. You probably have deleted it or you didn't import it back again after wiping... could that be?

[mlaeng]

@pvdyck pls let me know if that was the issue or if we have to look further...

[pvdyck]

I'll check in a couple of hours and get back to you, thanks for the great support

[pvdyck]

I just tried to scan a transaction on Polygon, it all worked perfectly. I suppose that the secret is still there. Could you please confirm that it disqualifies the "secret deleted" problem ? Could this be related to Optimism ?

[pvdyck]

Can you run the app in an emulator and check the logs ? Can I ( check the logs ) ?

[mlaeng]

@pvdyck it shouldn't be Optimism related, because Optimism interactions work just fine with my setup, which is pretty similar to yours. But I want to check something else as soon as I find time, thanks for your patience.

[mlaeng]

@pvdyck a thought I just had. Did you already try to remove the wallet from rabby and then connect it again?

[pvdyck]

No, will do and keep you posted. It's displayed properly in Rabby, the derivation path is correct.

[mlaeng]

is it another derivation index than 0?

[pvdyck]

Uninstalled/reinstalled Rabby / Reinstalled airgap vault's wallet - problem persists Same derivation index ( 0 )

Successfully signed transactions on Fantom, Avalanche, Polygon and BSC Only fails on Optimism

Hi @pvdyck

To successfully sign transactions on Optimism, you have to add Optimism to your Vault. Failure to do so will result in a black screen during the signing process. I've verified and reproduced this issue, and it consistently occurs when Optimism is not added to the Vault. Please make sure to include Optimism in your Vault to avoid encountering this problem. I will now close the issue.

[pvdyck]

Thanks ! It might be useful to catch this and display an informative message.

Thanks that solved it for me! It would be a good idea to actually mention this somewhere, this kept me up for hours!
