}FeeSettings Fields
The fields of the FeeSettings ledger entry depend on whether the XRPFees amendment was enabled the last time it was modified. If the last update was before the amendment became enabled, the entry uses the legacy format. If it has been updated after the amendment, it uses the current format. The fields it can have, in addition to the common fields, are as follows:
| Name | JSON Type | Internal Type | Required? | Description |
|---|---|---|---|---|
BaseFeeDrops | String | Amount | Yes | The transaction cost of the "reference transaction" in drops of XRP. |
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. |
PreviousTxnID | String | UInt256 | 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.) |

FeeSettings ID Format
