Ripple Custody adds Canton Network support for institutions

Introduction

Ripple Custody has added support for the Canton Network, a public Layer 1 blockchain used by regulated financial institutions. This integration allows institutions to manage Canton assets alongside their other digital holdings without bringing on a separate custodian.

Architecture and Security

The support arrives in Ripple Custody version 1.43, which launched on October 5, 2026. The platform uses a bring-your-own-validator (BYOV) model, where clients connect to validators they operate or their node providers already operate. Signing keys remain in the customer's vault, ensuring Ripple is not holding the keys to anyone's kingdom.

Benefits for Institutions

The integration brings several benefits for institutions, including sub-transaction privacy, pre-approvals, and two-step transfer offers. Existing custody policies and approval workflows carry over to every Canton transaction on the platform. Pre-approvals for incoming assets and two-step transfer offers allow institutions to manage Canton assets alongside their other digital holdings without bringing on a separate custodian.

Why Canton Matters

Canton is a public Layer 1 blockchain that has found favor with regulated financial institutions. The network offers sub-transaction privacy and runs on a network of networks structure. Major financial institutions including Goldman Sachs and BNY Mellon are using Canton infrastructure for tokenized assets. The integration with Ripple Custody enables institutions to manage Canton assets without the need for a separate custodian.

Conclusion

The integration of the Canton Network with Ripple Custody marks an important step for institutions looking to manage digital assets. The BYOV approach and secure signing key management ensure that institutions can bring their own validators and keep their cryptographic keys in their own HSM or KMS.
