ZEUS has released version 13.2.3 of its Bitcoin and Lightning wallet, bringing newer Lightning node software and security fixes into the mobile app. The stable release was published on October 12, 2026.

The official ZEUS release bundles embedded LND 0.21.4 and LDK Node 0.7.0-zeus-rl-0.2.7. ZEUS specifically notes that the LDK build includes rust-lightning 0.2.7 security fixes, alongside further security hardening, bug fixes and UI improvements.

The rust-lightning fixes are the most important part of the update. Its 0.2.7 changelog says the release fixes two funds-theft vulnerabilities and a denial-of-service vulnerability, in addition to several channel-state and HTLC handling bugs. Those issues matter because LDK provides the Lightning state machine and channel logic used by applications built on top of it.

UPDATE

Our Lightning node, Olympus by ZEUS, is back online.

Users whose channels were not closed during the security incident can now now send and receive payments through the node.

ZEUS has been publishing security updates throughout 2026; this earlier project post provides context for the wallet’s continuing hardening work.

For users running ZEUS with its embedded node, the practical change is straightforward: the wallet now carries the newer Lightning implementations instead of leaving those fixes only at the upstream library level. Users connected to their own remote LND or Core Lightning node should still maintain that server software separately.

This ZEUS walkthrough shows how the wallet’s embedded self-custodial Lightning node works on mobile.

The release arrives as Lightning is appearing in more user-facing infrastructure. BitcoinVersus.Tech recently covered Core Lightning’s latest security update, WhiteBIT adding Lightning deposits and withdrawals, and f2pool adding Lightning withdrawals for small mining balances. As more applications depend on Lightning, wallet and node-library patching becomes part of the payment infrastructure itself.

The confirmed development here is the software update, not a newly disclosed ZEUS exploit. ZEUS says 13.2.3 contains upstream rust-lightning security fixes and additional hardening. Users should rely on the project’s signed release artifacts and normal app-store update channels rather than unofficial packages.
