Swift says its MVP is built on an EVM-compatible architecture based on Hyperledger Besu; banks remain responsible for their keys, assets, funding and settlement. Taurus says institutions connecting to the ledger may need wallet and key-management, tokenization, custody and Besu/EVM connectivity capabilities.
What Swift’s shared ledger is designed to do
Swift describes the shared ledger as an additional layer in its infrastructure stack: a secure, real-time record that can sequence and validate transactions and apply rules through smart contracts. Its initial focus is 24/7 cross-border payments using bank-issued tokenized deposits. Interoperability with existing and emerging systems is a stated design goal, not evidence that every system is already connected. Swift’s project overview

In Swift’s description, the ledger coordinates the steps between participating institutions. It can record payment instructions, validate funding commitments and coordinate interbank processes. That makes it an orchestration layer for payment workflows rather than a new form of money or a substitute for every part of the existing payment chain. Swift’s MVP announcement
What it does not replace
Swift presents the ledger as an addition to its infrastructure, not a replacement for its messaging network. The ledger’s workflow coordination and shared transaction record are distinct from the messages institutions use to communicate payment instructions.

Nor does the ledger itself settle funds. Swift says participating banks retain authority over assets and funding, as well as settlement through real-time gross settlement (RTGS) systems, correspondent banking relationships or another mechanism agreed by the participants. A coordinated record of a payment and the final movement of funds are related but separate functions. Swift’s MVP announcement
The technology and division of responsibility
Swift says its MVP uses an EVM-compatible architecture based on Hyperledger Besu, an open-source blockchain foundation. EVM compatibility means the design supports Ethereum Virtual Machine-style smart contracts; it does not mean the ledger is a public Ethereum network. Swift says it will operate the ledger and coordinate the workflows, while banks retain control of their keys, assets, funding and settlement. Swift’s MVP announcement
- Swift’s stated role: operate the ledger, record and sequence transactions, validate funding commitments, and coordinate interbank processes.
- Participating banks’ stated role: retain authority over keys and assets, provide funding, and carry out settlement using an agreed mechanism.
- Smart contracts: encode workflow rules on the ledger, within the project’s proposed design.
These are descriptions of the project’s design from Swift, not independent verification of operational performance or settlement outcomes.

Connecting a bank’s existing systems to a shared ledger is not only a blockchain-node question. Taurus describes a set of products and infrastructure options for connectivity: programmable wallets and key management, tokenization, custody and permissioned Besu/EVM infrastructure. Which pieces an institution needs depends in part on what it already operates and where it wants those responsibilities to sit.
Wallets and key management
Taurus markets Taurus-PROTECT for programmable wallets and key management. These capabilities relate to controlling access to digital assets and signing transactions. They complement Swift’s stated arrangement in which banks retain authority over their keys; they do not transfer that authority to Swift.
Tokenization and custody
Taurus markets Taurus-CAPITAL for enterprise tokenization and Taurus-PROTECT for custody. Taurus says it integrated Swift smart contracts with these products on clients’ permissioned blockchain infrastructure. That is Taurus’s description of its integration, not a statement that every institution must use these products. Taurus’s integration announcement
Besu/EVM connectivity
A bank needs a way for its environment to communicate with the ledger’s EVM-compatible infrastructure. Taurus describes both managed Hyperledger Besu/EVM connectivity for institutions without their own setup and integration with infrastructure a bank already operates. Its options are Taurus’s offered implementation paths, not universal technical requirements set by Swift. Taurus’s Swift ledger page

Governance and operational ownership
Institutions also need to determine who controls keys, manages assets and funding, approves workflow rules, and executes settlement. Those responsibilities cross organizational boundaries: Swift describes itself as ledger operator and workflow coordinator, while banks retain control of key assets and settlement decisions. A bank assessing connectivity should map those roles against its own controls and its participants’ agreed procedures.

Two Taurus-described routes to connectivity
| Institution’s starting point | Taurus-described route | What to establish |
|---|---|---|
| No Besu/EVM infrastructure in place | Use Taurus’s managed permissioned Besu/EVM connectivity. | Confirm service scope, operating responsibilities, access eligibility and setup with Taurus. |
| Existing Besu or EVM-compatible environment | Connect Taurus to infrastructure the institution already operates. | Confirm compatibility, integration boundaries, key-management arrangements and governance. |
| Existing Taurus-PROTECT deployment | Taurus says clients can extend an existing instance. | Confirm the institution’s configuration and the work required for the extension. |
Taurus says Swift community membership is required for connection. Institutions should confirm eligibility and implementation details with Swift and Taurus, since availability and setup can change. Taurus’s Swift ledger page
What Taurus says about its integration and readiness
Taurus says it completed connectivity with Swift’s DLT infrastructure and integrated Swift smart contracts with Taurus-CAPITAL tokenization and Taurus-PROTECT custody on clients’ permissioned blockchain infrastructure. In an announcement dated 26 August 2026, Taurus described the integration as production-ready and said first live clients were expected shortly. That dated vendor statement does not establish broad live deployment, transaction volume or independently measured performance. Taurus’s 26 August 2026 announcement
Taurus co-founder and managing partner Lamine Brahimi said: “Financial institutions need digital asset infrastructure that can connect securely with the systems and networks they already use.” The statement captures Taurus’s case for integration infrastructure; it is the vendor’s view, not an independent assessment of the ledger’s security or readiness.

What banks should assess before choosing a path
- Whether the institution already operates Besu or another EVM-compatible environment, and what integration work that entails.
- Whether it prefers managed infrastructure or wants to retain operation of its existing environment.
- How wallet and key management, custody, and tokenization fit its control framework.
- How responsibilities for funding, workflow approval and settlement will be divided among the bank, Swift and other participants.
- Whether it meets Swift’s community-membership requirement and what access conditions apply.
Swift’s published materials describe the intended architecture and responsibilities; Taurus’s materials describe its products and connectivity options. Neither vendor’s statements alone establish adoption across the industry or measured benefits in live transactions.
