Note that here, BaseFeeMicronibiPerGas returns the gas base fee in units of the EVM denom and this is stored as a constant 1.
See here:
We can see that the gas base fee is 1 micronibi per gas. To put this into essence, this then means that regardless of the congestion of the network, the base fee is always 1 micronibi per gas. Any malicios users can spam the network with multiple transactions and pay very minute fees.
QA, since the user would still have to pay the gas cost.
Consider using a more dynamic base fee based on congestion of the network.
