Updated Ledger Entries

This page describes changes to existing ledger entry types for Sponsored Fees and Reserves.

Common Ledger Entry Updates

A new Sponsor field is added to the common ledger entry fields:

Field NameJSON TypeInternal TypeRequired?Description
SponsorStringAccountIDNoThe sponsor paying the owner reserve for this ledger object. When present, this indicates that the reserve burden for this object has shifted from the owner to the sponsor.

The Sponsor field may appear on the following ledger entry types:

  • AccountRoot
  • Check
  • Credential
  • Delegate
  • DepositPreauth
  • Escrow
  • MPToken
  • MPTokenIssuance
  • PayChannel
  • SignerList

RippleState entries also support sponsorship, but use the HighSponsor and LowSponsor fields instead of Sponsor. See RippleState Updates.

RippleState Fields

RippleState ledger entries can include the following new fields:

Field NameJSON TypeInternal TypeRequired?Description
HighSponsorStringAccountIDNoThe sponsor paying the reserve on behalf of the high account on the trust line.
LowSponsorStringAccountIDNoThe sponsor paying the reserve on behalf of the low account on the trust line.

The HighSponsor and LowSponsor fields exist because bidirectional trust lines may have the reserve held by two accounts.
