 The Masternode Hard Fork Signal (MnHfTx) special transaction adds the masternode hard fork signal produced by an LLMQ_400_85 quorum to the chain. Since this special transaction pays no fees, it is mandatory by consensus rules to ensure that miners include it. This can be done by any miner in any block, but it should only be included once.

-> Dash Core 18.0 only added the special transaction [to prepare for the full implementation](https://github.com/dashpay/dash/issues/4533) of [DIP23](https://github.com/dashpay/dips/blob/master/dip-0023.md) in a future release. The `mnhfsignal` P2P message referenced below is not included in Dash Core 18.0.
