What is new in version 3.4.0 of the xrpld XRP Ledger server software?

The full answer

What was released?

xrpld version 3.4.0 released. On September 16, 2026, xrpl.org announced that version 3.4.0 of xrpld, the reference server implementation of the XRP Ledger protocol, is now available [1]. The previous numbered release in the series, 3.3.0, was announced on August 6, 2026 [5]. Coin Alert News also dated the 3.4.0 release to September 16 [4].

What changes does it contain?

The xrpl.org release notes say the release introduces two new amendments, retires an amendment, and adds various bug fixes and build improvements [1]. crypto.news, summarizing the official release, named the two amendments as LendingProtocolV1_1 and fixCleanup3_4_0. It said the retired one is fixAMMOverflowOffer, whose post-amendment behaviour became a permanent part of the protocol [2].

What does LendingProtocolV1_1 add?

According to xrpl.org, LendingProtocolV1_1 extends Single Asset Vaults and the Lending Protocol with closed-ended vaults and cash-basis accounting [1]. Closed-ended vaults have a defined lifecycle of three phases: subscription, investment and redemption. These phases determine when assets can be deposited, when loans can be originated and when assets can be redeemed [1]. The release notes add that after the amendment is enabled, new loan brokers can only be created against closed-ended vaults [1].

Cash-basis accounting changes vault accounting so that interest is realized as income only when payments are made. The earlier model recognized all scheduled interest at the time of loan origination [1]. For the wider state of lending on the ledger, see whether native lending is live.

Do operators have to upgrade?

The release notes carry an action notice: anyone running an XRP Ledger server should upgrade to version 3.4.0 as soon as possible to ensure service continuity [1].

Is the new lending code active on mainnet?

No, as of the September 18, 2026 reports. crypto.news said the software release does not mean either new amendment is active on mainnet [2]. Its amendment-process description requires more than 80% support from trusted validators, held continuously for two weeks, before the rules become active [2]. Tron Weekly reported that no fixed activation date was announced for 3.4.0 and that mainnet rules change only if the required majority holds for the full period [3]. The approval path is explained in how amendments are approved.

What is the evidence against a quick rollout?

The vote counts are the strongest sign that activation is not imminent. crypto.news reported that a September 17 snapshot of XRPL Foundation validator-history data showed 16 of 35 trusted validators supporting SingleAssetVault and 13 of 35 supporting LendingProtocol [2]. The same article said Ripple’s validator had voted for both proposals in August, yet approval stayed well below the level required [2]. Crypto.news described them as a September 17 snapshot based on XRPL Foundation validator-history data, which showed 16 of 35 trusted validators supporting SingleAssetVault and 13 of 35 supporting LendingProtocol [2].

So what does the vote mean for control of the ledger? A release written by one group of developers still needs independent validators to approve it. The wider supply debate is covered in how many XRP exist, and who writes the software is covered in who funds XRP Ledger software. Earlier release details are on the version 3.3.0 page, and the broader feature picture is in features live and coming.
