Blockchain: IBM Connects Its Digital Asset Platform to Swift's Ledger

Blockchain enters the engine room. IBM connects its Digital Asset Haven platform to the shared ledger developed by Swift. Banks will thus be able to transmit instructions related to tokenized deposits using the payment formats they already employ, without immediately replacing their existing systems.

The company also opens a local version of its platform on IBM Z and LinuxONE. This option targets institutions that wish to keep their data and keys within their own infrastructure rather than relying on a public cloud.

Key Points

• IBM connects Digital Asset Haven to the shared ledger developed by Swift
• An ISO 20022 adapter allows banks to send instructions regarding tokenized deposits
• Assets can circulate continuously, while final settlement remains assured by traditional payment systems
• A local version is now in beta on IBM Z and LinuxONE mainframes

IBM Links Digital Asset Haven to Swift's Shared Ledger

Launched in October 2025 with wallet specialist Dfns, Digital Asset Haven provides banks, governments, and large enterprises with the necessary tools to store, transfer, and manage digital assets. The platform includes wallet management, transaction signing, and compliance checks.

IBM now adds a connection to permissioned blockchains, including the shared ledger designed by Swift. An ISO 20022 messaging adapter, still in beta, translates instructions related to tokenized deposits into the language already used by banking infrastructures.

A tokenized deposit represents on a blockchain an amount deposited with a bank. It remains recorded as a liability of the issuing institution and thus retains its status as a bank deposit. It is thus distinguished from a stablecoin, whose value depends on reserves held by a separate company.

This connection allows for moving these digital claims 24 hours a day, including on weekends. However, the final settlement continues to go through traditional systems, such as T2 in the eurozone or Fedwire in the United States. Swift thus maintains its role as orchestrator: its network transports the instructions but not the value directly.

The cooperative connects more than 12,500 financial institutions in over 200 countries and markets. More than forty institutions participated in the design of its shared ledger, of which 17 joined the pilot launched in July 2026. Citi, HSBC, BNP Paribas, UBS, Wells Fargo, Standard Chartered, BNY, DBS, and MUFG are among the participants. ![IBM connects its Digital Asset Haven platform to the shared ledger developed by Swift.

A Local Version for Bank Mainframes

The second announcement concerns the hosting mode of Digital Asset Haven. Until now offered primarily as a service, the platform can now operate directly on the systems IBM Z and LinuxONE installed in the banks' data centers.

This on-premises version, also available in beta, addresses a central constraint of the financial sector. Many institutions refuse to entrust their cryptographic keys, certain sensitive data, or their critical operations to a public cloud. A local deployment allows them to keep these elements within their own IT perimeter.

IBM protects key management with its Crypto Express hardware modules. These devices isolate cryptographic operations from the rest of the system and reduce the risks of extraction or manipulation of private keys.

This approach brings tokenized assets closer to the infrastructures that banks already use for their payments, databases, and internal controls. It also avoids a complete overhaul of existing systems: institutions add a blockchain layer while maintaining their compliance, credit, and risk management procedures.

IBM and Swift are advancing in a space already occupied by JPMorgan's Kinexys, Citi Token Services, and the Bank for International Settlements' Agorá project. However, their proposal relies on a particular combination: a global banking network, messaging standards already adopted, and mainframes present in many institutions. The blockchain is added here to the banking plumbing without immediately replacing existing pipelines.
