I have tried another testnet, amoy, and I have the same result. I was able to do a transaction on mainnet. But so far no testnet are working.

Thank you for your report!
I can confirm that in 12.13.0 on the latest Brave version:

• Base testnet transactions work
• I'm unable to send a tx on Polygon Amoy

Maybe it's worth mentioning that I was interacting with a contract in all cases.
