Version 1.35 is a short-term support (STS) SaaS release that introduces vault key rotation for MPC wrapping keys.
Ripple Custody version 1.35 introduces support of key rotation of the wrapping key for vaults deployed using multi-party computation (MPC).
For MPC vaults, in addition to the new v0_RewrapVaultKeyMaterial intent introduced in version 1.34, version 1.35 also introduces a new MPC node contract parameter, NEXT_KEK_PROVIDER_EMBED, to contain the new key encryption key (KEK) for updating both the customer-hosted and Ripple-hosted MPC nodes.
For more information and instructions, see MPC wrapping key rotation.
Ripple progressively deploys Version 1.35 across SaaS environments starting April 30, 2026.
Ripple takes great care in testing its applications and ensuring that there are no regressions or breaking changes. Should you experience unexpected behavior, reach out to the Support team by creating a ticket on our Support Portal or contact your Customer Partner Engineer (CPE).
