XRPL Developments Weekly Summary
May 18–24, 2026

TL;DR

A heavyweight week for rippled, where 26 PRs merged to the develop branch in a single day — including MPT/DEX fixes, lending protocol corrections, new invariant checks, a protocol bandwidth optimization, and a version bump to 3.2.0-b6. xrpl4j had its most productive week in months with 7 PRs merged, headlined by Lending Protocol (XLS-66) support (+11,084 lines across 88 files) and Dynamic MPT (XLS-94) support. On the developer portal, the Hooks feature page was marked inactive and replaced with Confidential Transfers and Lending cards. Confidential Transfers documentation updates merged on opensource.ripple.com.

Summary

This week saw a massive burst of activity on the core XRP Ledger server (rippled), where 26 changes were merged in a single day. None of these are live on the network yet — they all landed on the development branch and will only reach production when a new version is officially released. The changes include fixes to how Multi-Purpose Tokens behave on the decentralized exchange, corrections to the lending protocol's math (preventing rounding errors that could affect loan calculations), and a new bandwidth optimization that reduces the amount of data servers need to send each other when synchronizing their copies of the ledger. There's also a new safety feature: the server will now pause its cleanup of old ledger data if it detects gaps in its recent history, preventing potential data corruption.

The Java SDK (xrpl4j) had its most productive week recently, merging seven changes including full support for the Lending Protocol — which adds nine new transaction types for creating, managing, and repaying loans on the XRP Ledger — and Dynamic Multi-Purpose Tokens, which allow token properties to be updated after creation. These features will become available to Java developers once a new version is published to Maven Central. On the developer portal, the Hooks feature page was removed after three years without development, and replaced with links to Confidential Transfers and Lending — reflecting where active protocol development is focused. Documentation for Confidential Transfers was also updated on opensource.ripple.com, clarifying that transfer fees must be zero for confidential transactions and documenting the special transaction costs involved.

What Merged

Note: All rippled changes below were merged to the develop branch and are not yet live on the network. A tagged release is required for any change to reach production.

Note: SDK PRs below were merged to each library's main branch. They become available to application developers only after a tagged release is published (npm for xrpl.js, Maven Central for xrpl4j, PyPI for xrpl-py). If no corresponding SDK release appears in the data, treat the feature as merged-but-pending-release and phrase availability accordingly.

What to Watch Next Week


Community & Discussions

Institutional settlement feedback: A community member (first-time participant) shared operational feedback on building a settlement orchestrator bridging Corda, Apache Fineract, and XRPL in XRPL-Standards Discussion #545, discussing implementation around XLS-33, XLS-65, Escrow semantics, and audit-grade settlement evidence.

XLS-93 Token PayChan spec: Community contributor @dangell7 submitted a new draft spec for token-enabled payment channels in XRPL-Standards#536. @mvadari noted it needs rebasing to latest master before review can proceed.

xrpl-up tutorial contribution: A community member (@shichengripple001) submitted a new "Get Started with xrpl-up" tutorial to the developer portal (xrpl-dev-portal#3650), covering local sandbox setup and project scaffolding.

xrpl4j bug reports: Two new issues filed — UInt64Type missing LockedAmount in its base-10 field list, causing MPT escrow values to be parsed as hex instead of decimal (xrpl4j#792), and MpTokenMetadata lacking the protocol's 1024-byte max length validation (xrpl4j#791).

This week was a mirror image of last week: rippled swung from zero activity to 26 merges in a single day (Thursday), while XRPL-Standards went quiet after last week's 11-merge burst. xrpl4j had a strong week with 7 merges versus 2 last week — notably, the Lending Protocol (XLS-66) PR that was flagged as "In Progress" last week merged Wednesday, and the Dynamic MPT (XLS-94) PR merged Thursday. The xrpl4j NPE fixes (#785, #786) also carried over from last week's "In Progress" list and landed. The single release (Clio nightly) is down from last week's 4 releases.
