= xref:CTxMemPool.adoc[CTxMemPool]::GetMinFee
:relfileprefix: ../
:mrdocs:

The minimum fee to get into the mempool, which may itself not be enough for larger‐sized transactions. The m_incremental_relay_feerate policy variable is used to bound the time it takes the fee rate to go back down all the way to 0. When the feerate would otherwise be half of this, it is set to 0 instead.
