# Ripple Custody 1.35 (April 30, 2026)

Version 1.35 is a short-term support (STS) SaaS release that introduces vault key rotation for MPC wrapping keys.

## MPC wrapping key rotation

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](/products/custody/v1.36/support/change-history/v134), 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](/products/custody/v1.36/identity-and-access/vault-management/vault-wrapping-key-rotation-mpc).

## Distribution and deployment

Ripple progressively deploys Version 1.35 across SaaS environments starting April 30, 2026.
