IBM Bridges Traditional Banking And Blockchain: Swift Ledger Integration And On-Premises Digital Asset Haven Now In Beta
In Brief
IBM integrates Digital Asset Haven with Swift’s blockchain ledger for 24/7 tokenized deposits and launches an on-premises beta on IBM Z and LinuxONE for secure in-house digital asset management.
IBM announced that it has integrated its digital asset management platform, IBM Digital Asset Haven, with Swift’s blockchain-based shared ledger, enabling financial institutions to carry out tokenized deposit transactions through standard payment messaging. Through a beta release of an ISO 20022 message adapter, banks can instruct such transactions using their existing message formats and operational processes, avoiding the need to adopt blockchain-specific workflows.
The integration arrives amid a broader modernization of payments infrastructure across the banking sector, as institutions seek more efficient cross-border money movement and a way to manage a growing range of digital assets. Swift, the cooperative that connects more than 12,500 financial institutions across over 200 markets, first unveiled its shared ledger at Sibos 2025. The platform is based on a prototype developed in collaboration with Consensys and was designed with input from more than 40 financial institutions worldwide. It progressed from concept to activation within nine months, and 17 institutions are currently piloting tokenized deposit transactions on it.
The ledger supports bank-issued tokenized deposits, allowing participating IBM clients to move digital assets around the clock, ahead of final settlement, which continues to be completed through existing systems. Banks retain the use of established Swift standards and their own compliance processes. Financial institutions already involved in the program have successfully tested tokenized deposits on the Swift ledger using Digital Asset Haven.
On-premises deployment brings digital asset operations in-house
In parallel with the Swift integration, IBM is extending Digital Asset Haven to an on-premises beta deployment, giving regulated organizations the option to manage digital assets such as stablecoins and tokenized deposits entirely within their own data centers. The SaaS and hybrid versions of the platform have been available since October 2025, and banking and payment institutions across several continents have since begun implementing digital asset use cases on it.
The on-premises version runs on IBM Z and IBM LinuxONE systems with no dependency on public cloud infrastructure, either on hardware clients already operate or on newly added capacity. Its key features include client-controlled deployment, with both the solution layer and key management layer remaining inside the client’s own environment at configurations designed to reach 99.999999% availability. Keys are protected by IBM Crypto Express hardware security modules, while confidential computing and environment partitioning separate production, test, and development workloads. Formal, auditable key ceremonies govern the generation of root certificate authority keys, producing documentation suitable for regulatory review, and the platform supports cold storage operations through the IBM Offline Signing Orchestrator.
Because the on-premises edition shares the same architecture, APIs, and workflows as the SaaS and hybrid options, clients can switch between deployment models without rewriting their applications — an arrangement aimed at institutions that want to expand into digital assets without ceding control over their technology stack.
