Hi 
I’d like to execute a method on a smart contract in mainnet via
oz send-tx --network main
but I get:
Error while trying to send transaction to 0x..... Error: transaction underpriced
What could be the root cause and how can I proceed here?
Many thanks in advance!

stupid me. It was a too low gas price.
Hi @itinance,
I’m glad that you were able to resolve. 
I recommend manually checking EthGasStation at the moment. https://www.ethgasstation.info/
Network congestion means we have seen all sorts of gas prices.
As I write this fast is 89Gwei which is at the lower end of some of the numbers I have seen recently.
