FeeSettings

[Source]

The FeeSettings entry contains the current base transaction cost and reserve amounts as determined by fee voting. Each ledger version contains at most one FeeSettings entry.

Example FeeSettings JSON

{
   "BaseFee": "000000000000000A",
   "Flags": 0,
   "LedgerEntryType": "FeeSettings",
   "ReferenceFeeUnits": 10,
   "ReserveBase": 20000000,
   "ReserveIncrement": 5000000,
   "index": "4BC50C9B0D8515D3EAAE1E74B29A95804346C491EE1A95BF25E4AAB854A6A651"
}

FeeSettings Fields

In addition to the common fields, the FeeSettings ledger entry has the following fields:

Name	JSON Type	Internal Type	Required?	Description
`BaseFee`	String	UInt64	Yes	The transaction cost of the "reference transaction" in drops of XRP as hexadecimal.
`Flags`	Number	UInt32	Yes	A bit-map of boolean flags enabled for this object. Currently, the protocol defines no flags for `FeeSettings` objects. The value is always `0`.
`LedgerEntryType`	String	UInt16	Yes	The value `0x0073`, mapped to the string `FeeSettings`, indicates that this object contains the ledger's fee settings.
`ReferenceFeeUnits`	Number	UInt32	Yes	The `BaseFee` translated into "fee units".
`ReserveBase`	Number	UInt32	Yes	The base reserve for an account in the XRP Ledger, as drops of XRP.
`ReserveIncrement`	Number	UInt32	Yes	The incremental owner reserve for owning objects, as drops of XRP.
`PreviousTxnID`	String	Hash256	No	The identifying hash of the transaction that most recently modified this entry. (Added by the fixPreviousTxnID amendment.)
`PreviousTxnLgrSeq`	Number	UInt32	No	The index of the ledger that contains the transaction that most recently modified this entry. (Added by the fixPreviousTxnID amendment.)

Warning

The JSON format for this ledger entry type is unusual. The BaseFee, ReserveBase, and ReserveIncrement indicate drops of XRP but not in the usual format for specifying XRP.

If the XRPFees amendment is enabled, the FeeSettings object has these fields instead:

Name	JSON Type	Internal Type	Required?	Description
`BaseFeeDrops`	String	Amount	Yes	The transaction cost of the "reference transaction" in drops of XRP.
`Flags`	Number	UInt32	Yes	A bitmap of boolean flags enabled for this object. Currently, the protocol defines no flags for `FeeSettings` objects. The value is always `0`.
`LedgerEntryType`	String	UInt16	Yes	The value `0x0073`, mapped to the string `FeeSettings`, indicates that this object contains the ledger's fee settings.
`ReserveBaseDrops`	String	Amount	Yes	The base reserve for an account in the XRP Ledger, as drops of XRP.
`ReserveIncrementDrops`	String	Amount	Yes	The incremental owner reserve for owning objects, as drops of XRP.

FeeSettings Flags

There are no flags defined for the FeeSettings entry.

FeeSettings ID Format

The ID of the FeeSettings entry is the hash of the FeeSettings space key (0x0065) only. This means that the ID is always:
