Hey, I just want to mention that when we are signing and sending tx in status-go we are always setting suggested (by eth network) gas price and estimated gas limit if they are not provided.

Thanks @dshulyak ! We want to own those values UI side as we have to display it and allow user to modify this default.

Shouldn't this code be moved to effects?

@rasom Updated to a fx

If use Send Transaction from Wallet: I assume that Gas price adjustment should work for mainnet too. I’ve switched to mainnet with ropsten RPC but see 20 Gwei instead of SafeLow 1 Gwei (at least according to https://ethgasstation.info/index.php ) In the same time 1 Gwei is shown ok for testnets.
