FeeSettings

[Source]

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

Example FeeSettings JSON

Example FeeSettings object:

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

FeeSettings Fields

The FeeSettings object 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.

Warning: The JSON format for this ledger object 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 ID Format

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

4BC50C9B0D8515D3EAAE1E74B29A95804346C491EE1A95BF25E4AAB854A6A651
