## `feemarket`

### Abstract <a href="#abstract" id="abstract"></a>

This document specifies the feemarket module which allows to define a global transaction fee for the network.

This module has been designed to support EIP1559 in cosmos-sdk.

The `MempoolFeeDecorator` in `x/auth` module needs to be overrided to check the `baseFee` along with the `minimal-gas-prices` allowing to implement a global fee mechanism which vary depending on the network activity.
