After submitting the transaction operation, it has not been completed, as long as 12 hours

I submitted a matic/usd transaction on matcha at around 8 o’clock last night. I couldn’t complete or cancel the operation after multiple confirmation/cancellation/replacement of RPC. Until now I can’t complete any operation. Can anyone help me?

There is not topic on the polygonscan

I probably know the reason, none of the above transactions are on the chain, so no matter how I cancel it, the situation cannot be changed.
The problem lies in RPC. To be honest, MATIC is the worst blockchain I have ever used, and it’s been a whole day since this problem occurred today.

The next step must be crazy :slight_smile:
