Trying to swap 0.11 Eth to Usdc it keeps returning a error message. The error message only appears when swapping eth for usdc.
Swapping deus or dea to Usdc seems to give no problems.

Maybe it also has to do with rinkeby and not the app itself?

Steps to reproduce

1. flutter build apk
2. Install the apk on your phone (or an emulator - just be sure that you have a release build of the APK, not a debug build!)
3. Launch the app, create a wallet or import one
4. After confirming, wait until the swap screen loads

Expected behavior

The swap service should initialize for a few seconds, indicated by a CircularProgressIndicator. Afterwards, I can select tokens etc. in order to swap.

Actual behavior

The CircularProgressIndicator doesn't disappear and just keeps spinning.

I suppose the internet connection or something like that is blocked? Everything worked fine when I tried it out in debug mode.
On the other hand, I noticed that you integrated <uses-permission android:name="android.permission.INTERNET"/>. Any ideas?

Steps to reproduce:

1. Load the app ( & log into wallet with a balance)
2. Leave ETH -> DEUS as the default trading pair.
3. Use 0.02 as from value
4. Click on Swap
5. Click on the 'EDIT' button above the gas fee.
6. In the upper right corner, click on Advanced.

Expected behavior

I get a new screen where I can customize my GAS limit.

Actual behavior

Screen gets stuck / the whole UI freezes.
Console throws no error.

Hint: I commented out the advanced button so it won't delay the launch that much. For bugfixing, you need to uncomment it again, otherwise you won't be able to reproduce the error because the button is missing.
Can you please take care of it?

Steps to reproduce:

1. Load the app
2. Select DEA as From Token
3. Select USDC as To Token
4. Enter 0.02 as From Amount
5. Click on Swap

Expected behavior

Appearance of a gas customization screen or a pending transaction.

Actual behavior

Screen gets stuck in loading behavior.

Console throws error:
