XRPL client prereleases carry Confidential MPT and Sponsorship
Serguey Asael Shinder1 min readTwo prerelease packages published on 23 September 2026 show what the XRP Ledger's JavaScript tooling is now able to speak. [email protected] and [email protected] are tagged on a named channel rather than as ordinary releases: https://github.com/XRPLF/xrpl.js/releases/tag/xrpl%405.4.0-smartescrow.0.
The changelogs list, among routine release automation, support for Confidential MPT (XLS-0096) and work labelled Sponsorship (XLS-68), alongside updated binary-codec definitions.
What it means
A client library is where a ledger amendment becomes usable, and it usually gets there first. Definitions in the binary codec are what let a wallet or service construct and read a transaction type at all; until they ship, an amendment that is live on the network is unreachable from ordinary tooling. Watching the codec is therefore a decent early indicator of what the ecosystem expects to need.
The named prerelease channel is the honest part of this. Publishing as -smartescrow.0 rather than as a version bump says plainly that this is a track for a feature still settling, not a general release - which is what anyone pinning a dependency needs to know before a package manager decides for them.
⚠️ These are prereleases, and we are reporting what their changelogs contain. Nothing here says an amendment is activated, scheduled or voted in; the state of any amendment lives on the ledger and should be read there.
