Bitcoin MempoolInfo Structure MempoolInfo Active state of the transaction memory pool from getmempoolinfo. struct MempoolInfo Overview Fee rate fields (mempoolminfee, minrelaytxfee, incrementalrelayfee) are in BTC/kvB (not satoshis, not BTCAmount). Note Targets Bitcoin Core v31.x. Fields marked optional were added in v24+. Topics Initializers init(from: any Decoder) throws Instance Properties let bytes: IntSum of all virtual transaction sizes (BIP 141). let fullrbf: Bool?Whether the node has full replace-by-fee enabled (v24+). let incrementalrelayfee: Double?Minimum fee rate increment for mempool limiting or replacement in BTC/kvB (v24+). let loaded: BoolWhether the mempool is fully loaded. let maxmempool: IntMaximum memory usage for the mempool in bytes. let mempoolminfee: DoubleMinimum fee rate in BTC/kvB for tx to be accepted. let minrelaytxfee: DoubleCurrent minimum relay fee for transactions in BTC/kvB. let size: IntCurrent transaction count. let totalFee: BTCAmount?Total fees of all transactions in the mempool in BTC (v22+). let unbroadcastcount: IntCurrent number of transactions that haven’t passed initial broadcast yet. let usage: IntTotal memory usage for the mempool in bytes.
