Currently, transactions cost at least 0.002 XMR per kB.

If a miner includes a transaction with a lower fee, will his block be rejected by the network?

1 Answer 1


The block will not be rejected if it's included in a block mined by another miner who accepted it. See src/cryptonote_core/tx_pool.cpp, line 137 (or just after FEE_PER_KB).

This implies a miner is free to mine transactions with a fee lower than this, and any block found with such transactions will be accepted.

    What a confusing first-glance Q & A.What's the etiquette on editing the initial question and the accepted answer so that the title and the question aren't opposites? As it stands, at first glance it seems you are answering "No" to "Can miners choose to accept lower fees" but you are really answering "No" to "will his block be rejected". Aug 25, 2016 at 16:53

    Good point, I made it clearer.
