Developers working on the XRP Ledger have put forward a change to how loan repayments are rounded, aiming to stop tiny calculation differences from piling up across a repayment schedule. The proposal was filed on GitHub on November 6 and sits inside the planned LendingProtocolV1_2 amendment for native lending, according to crypto.news.
Under the current design, each installment’s value is calculated separately, and the leftover rounding can leave a borrower’s final payment one unit above the scheduled amount. The change would tie the outstanding balance to the remaining schedule instead, and it has not been activated on mainnet.

Key facts
- The proposal was posted to pull request #8698 in the XRPLF rippled repository on November 6, 2026.
- It introduces a calculation method called telescoping, which derives the outstanding balance from the remaining repayment schedule after each installment.
- Each on-time LoanPay would reduce TotalValueOutstanding to the scheduled amount with one fewer payment left, capped at the rounded PeriodicPayment.
- Tests cover the Legacy, CashBasis and FixedPrecision vault accounting models, with and without the amendment enabled.
- Activation requires support from more than 80% of trusted validators for two consecutive weeks, and no mainnet activation date has been announced.
What the code changes touch
The work is split into two commits. The first moves the calculation of a loan’s scheduled value out of computeLoanProperties into a separate function named scheduledValue; developers say it does not change existing behaviour, and its purpose is to make loan creation and repayment use the same rounding method. The second adds the repayment correction under LendingProtocolV1_2, including a reset of TotalValueOutstanding to the scheduled value after an accepted overpayment, so later installments follow the updated schedule.
Safeguards cover the principal portion of an installment so calculations cannot leave unpaid interest below zero. Zero-interest loans need separate handling because their total value rounds to the nearest unit while the principal rounds upward. U.Today reported that the value portion of every on-time payment would become either the floor or the ceiling of PeriodicPayment and at least one unit, with the last payment matching the rounded PeriodicPayment exactly.

Existing loans keep some differences
Loans already carrying one unit above their scheduled balance would retain that difference until the borrower overpays, so those borrowers could still face a final installment of the rounded PeriodicPayment plus one unit. Small overpayments that fall within existing rounding limits may be ignored: the transaction can succeed without charging an extra loan payment. Both outlets note the impact on users today is small, and crypto.news states the adjustment concerns loan accounting in the proposed protocol rather than ordinary XRP transfers or a new borrowing product for all XRP holders.
Why it matters
Native lending is the piece of the XRP Ledger roadmap that would let fixed-term loans be funded through Single Asset Vaults, with brokers assessing borrowers and managing credit risk off-chain. Accurate repayment arithmetic matters to anyone who would build on that base, even if the visible effect is a single unit on a final installment. Version 3.4.0 introduced closed-ended vaults and cash-basis accounting under LendingProtocolV1_2’s predecessor, LendingProtocolV1_1, but an October review of validator voting found the lending and vault amendments short of the support needed to activate. A separate maintenance amendment that activated on November 4 addressed transaction-processing issues without switching on lending.
What to watch
Pull request #8698 remains open and no vote on LendingProtocolV1_2 has been announced. The decisive marker is whether trusted validators sustain more than 80% support for two consecutive weeks; until then the fix stays a proposal.
