XRP Ledger fixCleanup3_4_0 amendment activation

23 October 2026, Friday
Online Location
XRP XRP Ledger

The fixCleanup3_4_0 amendment is scheduled to become active on the XRP Ledger on October 23, 2026 at 09:34 UTC, after holding an 80% validator majority for two weeks. It affects XRP and the network software that processes it.

What is happening

An amendment is a change to the rules by which the XRP Ledger checks transactions. Once enough validators agree and the approval holds for two weeks, the change becomes permanent for all later ledger versions, and undoing it requires another amendment. fixCleanup3_4_0 reached the required majority on October 9, 2026 at 09:34:30 UTC, which sets the activation exactly two weeks later.

The amendment is a bundle of corrections rather than a single patch. According to the XRP Ledger documentation, it touches Single Asset Vaults, the lending protocol, the automated market maker, the permissioned DEX, trust lines, NFTs, multi-purpose tokens and escrow, among other areas. Examples include more precise rounding in vault deposits and withdrawals, a stricter rule that a loan counts as in default only once its due date has fully passed, and separate signature prefixes for sponsor and counterparty signatures.

The bundle follows earlier routine fix amendments (fixCleanup3_1_3, fixCleanup3_2_0 and fixCleanup3_3_0), which are already active. Because the majority must be maintained, the date holds only as long as support stays above 80%; if it falls below, the two-week window restarts.

Why it matters

For people who simply hold or trade XRP, nothing needs to be done: balances, addresses and payments are unaffected, and there is no fork, token swap or freeze on deposits or withdrawals. Exchanges and wallet providers run their own nodes and are expected to keep their software current.

Operators of their own rippled node or validator are the ones who must act. A server running a version that does not know the amendment becomes amendment-blocked, meaning it stops following consensus and no longer serves reliable data. Notably, the fixes cover Single Asset Vaults and the lending protocol, neither of which is active on mainnet; those features still lack an 80% majority. The activation therefore adds no new feature and does not set a start date for lending. It is a maintenance step, and nothing in it implies a price outcome.
