For information about distribution and deployment of this version, see [Distribution and deployment](#distribution-and-deployment). ## Key management This release introduces the following key management enhancements. ### Support for SLIP10 on Thales Luna HSMs Ripple Custody now supports SLIP-10 key derivation for vaults created with Thales Luna HSMs (complementing existing BIP32 capabilities). This includes ed25519 curve compatibility, ensuring improved cross-chain interoperability, enhancing flexibility and security in key management. Note: This feature requires Thales Luna HSM firmware version 7.8.7 or newer and it's available exclusively for newly created vaults configured with KMS Connect Luna connection. Required app software version: In addition to using HSM firmware version 7.8.7 or newer, you must also use Luna Appliance Software 7.8.5-300 to be able to perform SLIP10 derivation. ### MPC Ripple Custody introduces Multi-Party Computation (MPC) as a new key management option. Ripple’s proprietary MPC solution uses a 3-of-4 threshold signing scheme, distributing key shards across customer and Ripple-hosted infrastructure to ensure no unilateral key usage and protection against shard loss. MPC supports flexible node deployment in cloud environments like AWS, GCP, and Azure, with Ripple nodes ensuring high availability and backup. Built-in shard recovery prevents data loss, while relay nodes and load balancing enable seamless scaling for enterprise needs. Note: This feature is currently a closed beta. ## User experience This release introduces the following user experience enhancements. ### Simplified UI A button at the top of the page allows you to switch between the current Ripple Custody UI and the new beta UI, designed for improved performance and an enhanced experience. *Switching from the beta version to the current version of the UI* ![Beta UI](/assets/beta-ui.da39913faa029bfb886c457b5b01d0d985dbc9876e4d11483a8fac2419a8982a.2bbcbdb9.png) The beta UI focuses on core reading functionalities like list and details pages and introduces the following new side navigation: - **Home** -- the landing page - **Intents** – Lists intents, including the initiator, applied policies, creation date, last update, and status - **Accounts** – Lists accounts, including the providers and ledgers that are associated with the account - **Endpoints** – Lists endpoints, including their trust score, address alias, address, ledger, last update, and status - **Transactions** – Lists transactions, including the date, number of transfers, the type of transaction (internal/external), the transaction’s ID on the ledger, source, destination, and value. - **System admin** – Contains system management for users, domains, and policies - **Custody admin** – Contains Custody administration for assets, and vaults The **Logout** is now located in the user management section in the upper right.
