Ripple Custody version 1.43 adds support for the Canton Network, letting banks and funds hold and transfer Canton assets within their existing custody platform. Signing keys stay in the customer's own HSM or KMS, and prepared transactions get a 24-hour signing window.

• Update shipped October 5, 2026, support confirmed October 7
• Access is API-only, with no arbitrary Canton commands or DvP workflows
• Supports Canton Coin (Amulet) and CIP-56 tokens
• Signing keys remain in the customer's HSM or KMS, not with Ripple
