Feemarket

Abstract

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 overwritten to check the baseFee along with the minimal-gas-prices allowing to implement a global fee mechanism which vary depending on the network activity.

For more reference to EIP1559:
