When trying to finalize the IBAN connection in the Gnosis App, you may encounter an error message that reads "Error: Authorization code missing in redirect". This error typically occurs during the final step of the IBAN setup process when the app attempts to connect with Monerium to complete the integration.
Answer
This error occurs because your Monerium account configuration is not properly directed to your Gnosis App wallet. The IBAN is currently linked to a different wallet address than your Gnosis App wallet, which prevents the authorization flow from completing successfully.
To resolve this issue, you need to configure your Monerium account to use your Gnosis App wallet address. Follow these steps:
Add an external owner to your Gnosis App wallet:
Add an external owner (this can be a MetaMask wallet)
Get your Gnosis App wallet address:
Go to the wallet page > deposit > receive to the wallet address
Click on the address to copy it
Connect your MetaMask wallet to Monerium:
Connect using the MetaMask wallet you added as an external owner
Import your Gnosis App wallet to Safe:
Add the Gnosis App wallet to your accounts
Make sure your external owner's address is set as a signer
Connect the Safe wallet to Monerium:
Return to https://monerium.app/wallets
Add a wallet with Safe
Select your imported Gnosis App wallet to connect with Monerium
Verify that the Gnosis App Safe is connected to Monerium
Complete the IBAN setup in Gnosis App:
Use your passkey to authenticate
Wait for the IBAN to be set
If you continue to experience issues after following these steps, the development team is aware of this as an edge case and is working on a fix. In the meantime, you can still receive funds to your IBAN through the Monerium interface, even if the Gnosis App integration is not fully completed.
Note: Unfortunately, Gnosis support cannot make changes to your Monerium account configuration directly. All Monerium account modifications must be done by you through the Monerium interface.
