IBM EXPANDS DIGITAL ASSET STORAGE WITH FAST LEDGER CONNECTIVITY. IBM is testing connectivity between Digital Asset Haven and Swift’s common ledger as banks explore tokenized deposits and blockchain-based payment infrastructure. IBM is testing methods to connect its digital assets platform with existing banking infrastructure as financial institutions investigate tokenized deposits and blockchain-based payment systems. In a September 24 announcement, IBM said customers using Digital Asset Haven can connect to Swift’s common ledger via a beta ISO 20022 messaging adapter. The company is also testing an on-premises version of the platform for organizations wishing to operate the software within their own data centers. These two solutions address different components of the infrastructure: the Swift adapter focuses on messaging and ledger connectivity, while the on-premises version relates to how organizations deploy and manage their digital assets systems. IBM Tests ISO 20022 Connectivity with Swift Ledger The beta adapter enables Digital Asset Haven customers to initiate tokenized deposit transactions using ISO 20022, a widely adopted financial messaging standard. Rather than requiring banks to adopt a separate blockchain-specific messaging process, the adapter is designed to translate existing financial messages for use with Swift’s common ledger environment. Swift’s network connects over 12,500 financial institutions across more than 200 markets. Swift’s common ledger is being developed to support transactions involving bank-issued tokenized deposits and other digital assets. Swift announced the common ledger project at Sibos 2025 following collaboration with over 40 financial institutions. In July, Swift stated the ledger was ready for initial use, with 17 banks from six continents preparing to test real-world transactions. Participating institutions include ANZ, BNP Paribas, BNY, Citi, DBS, HSBC, Standard Chartered, UBS, and Wells Fargo, among others. Initial use cases focus on 24/7 cross-border payments involving tokenized deposits, while final settlement continues to rely on existing payment systems. IBM said participating organizations have tested tokenized deposit formats through Digital Asset Haven, though it did not name the institutions. Banks Testing Tokenized Deposits Tokenized deposits represent commercial bank deposits on a blockchain platform. Unlike stablecoins, they remain liabilities of the issuing bank. Financial institutions have been and continue to study this model for applications including cross-border payments, settlement, and corporate transactions. Swift’s project exemplifies how banks are testing whether distributed ledger infrastructure can operate alongside existing payment systems rather than fully replacing them. However, the technology remains in testing phases, and its practical benefits will depend on how participating organizations handle payment processing, compliance, reconciliation, and integration with existing systems. IBM also cited a JP Morgan Payments survey indicating that 93% of financial institutions are modernizing their payment infrastructure. This figure encompasses general payment modernization and does not specifically measure adoption of blockchain technology or tokenized deposits. Digital Asset Storage Platform Adds On-Premises Option IBM is separately testing an on-premises version of Digital Asset Haven with select customers. The software is being tested on IBM Z and LinuxONE, enabling financial institutions to operate the platform within their own data centers rather than relying entirely on public cloud infrastructure. The system includes digital asset management and key management components capable of operating within an organization’s existing environment. IBM said the system can leverage its Crypto Express and Offline Signing Orchestrator hardware security modules to perform transaction signing operations. The on-premises deployment model complements the SaaS and hybrid deployment options IBM introduced for Digital Asset Haven in October 2025. IBM said financial institutions across multiple regions have begun deploying digital asset use cases on this platform, though the company did not name the organizations. IBM’s Blockchain Patent Agreement with Circle This announcement follows a separate blockchain patent transaction between IBM and Circle in July. On July 27, Circle announced it had acquired nearly 1,000 blockchain patents from IBM. These patents include intellectual property related to blockchain and are distinct from IBM’s current work with Swift and Digital Asset Haven. Both companies stated they will seek additional commercial opportunities following this transaction. The agreement comes as banks, stablecoin issuers, and technology companies continue developing infrastructure around tokenized assets and digital payments. Both projects remain in testing phases.Neither of IBM’s two latest developed products can replace existing banking infrastructure. Swift’s universal ledger is still in the testing phase, with participating financial institutions experimenting with encrypted fund transfers. Similarly, IBM’s Digital Asset Haven, deployed on-premises, is being offered to a select group of customers through a beta trial program, and interested organizations are placed on a waiting list. These projects demonstrate that banks and technology providers are testing ways to connect blockchain-based assets with existing messaging, custody, and payment systems. Next steps will depend on the systems’ performance during real-world testing or scaling, including their ability to handle operational processes, regulatory requirements, security, and integration with existing financial infrastructure.
