The XRP Ledger's critical fixCleanup3_4_0 upgrade is expected to activate on October 23, 2026, at 9:34 AM UTC. This upgrade requires over 80% support for 14 days to take effect and includes approximately 25 changes, such as exempting IOU issuers from global freezes on NFT offers in their own currencies, and modifying authorized trust lines to implicitly authorize pseudo-account counterparties.
