Subject: [PATCH]  Need to increase priorityFees on Polygon

Need more agressive priorityFees since april-23 otherwise transactions on Polygon got stuck (in MATIC it is about +0.01 to ~0.05 overall fee).
You can reproduce that issue by signing any tx on Polygon DAO by Client. And comparing to manually set 'agressive' gas fee in Metamask (the last one will work).
