# Ripple Custody 1.28 (November 14, 2025)

Version 1.28 is a SaaS release that introduces two new Ripple Custody features:

- Multi-party computation (MPC) backups
- Coinbase adapter (CBA) key rotation


## Multi-party computation (MPC) backups

Ripple Custody Version 1.28 introduces the ability for customers to generate a backup of a key-management system (KMS) deployed using multi-party computation (MPC).

Ripple does its own backups for disaster recovery purposes. This feature is for customers who want or require the ability to create their own backups to maintain in their own possession.

To accommodate customer-generated MPC backups, Ripple Custody Version 1.28 introduces the following changes:

* Two scripts are provided by your Ripple liaison to help create and validate backups:
  * The *backup key-generation script* — This script generates both a public encryption key that you will provide to Ripple Custody for creating backups, and a private decryption key that you store in your own KMS separate from Ripple.
  * The *backup verification script* — This script lets you verify the validity of a backup that you have generated and downloaded in JSON form.
* Both the `v0_CreateVault` and `v0_UpdateVault` intents now have a `backupEncryptionKey` parameter where you can specify the encryption (public) key to use when you request a backup.
* Two new intents:
  * `v0_CreateBackup` lets you request the generation of a backup to download.
  * `v0_AcknowledgeBackup` lets you acknowledge the receipt of the backup.
* Three new API operations:
  * [**Get Backup information**](/products/custody/v1.34/api/reference/openapi/backups/getbackup) lets you check the status of a specific backup to know when it is ready for download.
  * [**List Backups**](/products/custody/v1.34/api/reference/openapi/backups/getbackups) lists all pending and processed backups.
  * [**Get Backup trusted entity details**](/products/custody/v1.34/api/reference/openapi/backups/getbackuptrustedentity) lets you download the completed backup.

## Coinbase adapter (CBA) key rotation

The Coinbase adapter (CBA) is a subcustodian system that allows customers to use Ripple Custody to manage and secure their assets on Coinbase Prime using the Coinbase API. For those customers, the CBA is a critical piece of infrastructure that requires a high-level of security and operates under a strict policy-governed control framework.

Ripple Custody version 1.28 adds the ability to rotate the secrets on which the trust in the CBA relies.

Version 1.28 introduces a new intent, `v0_AddProviderKey` to allow key rotation for the CBA.

For more information, CBA customers should contact their Ripple liaison.

## Distribution and deployment

The 1.28 version will be progressively deployed across SaaS environments starting on October 24, 2025 with production environments scheduled for deployment on December 1, 2025.
