Scan this (address) QR code with Metamask does not work #188

1) I wanted to send funds from Metamask (v10.25.0 on Chrome) on Linux Desktop to an account in Airgap-Vault.

I notided that the camera image is mirrored, but even after I mirrored the Airgap-Vault QR-code it did not work. Chosing QR code v2 or v3 on Airgap-Vault does not work either.

2) Note : The other direction worked

The Airgap Vault app is only to manage secrets and sign transactions. To manage funds on addresses/accounts, you need the Airgap Wallet app (either on the same device or a different device) If you use the Airgap Wallet app, you can derive an ETH address from the secret in your vault. You will then see that account/address in Airgap Wallet. If you tap on it you will see a "receive" button and if you tap on that, the address QR code will be displayed. This is the one you would scan with Metamask.

see this video from exactly 3:19 https://www.youtube.com/watch?v=M9ICKaLxuwQ&t=199s in the example it's a BTC address, but it would work the same with an ETH address. In the front, that's the Airgap Wallet app. In the back, thats the Airgap Vault app

I just installed AirGap Vault 3.25.0

1) Is actually pretty easy. I can just use : [Menu] > [Show Address QR] .. scan it with Metamask (laptop webcam)

2) I just tried this with Optimism network, expecting that every EVM chain should behave pretty identical, and Metamask would just send the signed transaction to another chain / RPC node ... however I got an error within AirGap Vault when trying to scan the Metamask QR-code of the transaction.

[Update] : I just read in the telegram group that Optimism is apparently the only chain not working .. so maybe I was unlucky just to use that one for testing.

However, I just tested it with Polygon zkEVM testnet and i worked great !!!

@SvenMeyer in the meantime Optimism should be supported as well. Make sure you get the latest version. I'll close this issue...
