The Bank of England’s Digital Pound Lab is hosting an experiment that combines a stablecoin settlement leg with a simulated digital-pound leg in one cross-border trade-finance workflow.
Polygon Labs announced its participation with NOBO Finance and Dun & Bradstreet on August 11. The Bank of England’s Phase 2 page lists the three companies as a participating group, while independent reporting published on August 12 described the work as a test of interoperability between stablecoins and a possible UK central bank digital currency.
The distinction between a laboratory test and a live payment service is central to understanding the project. The environment uses no real customers or money, and the Bank has not decided whether to issue a digital pound. The central bank also says participant-designed experiments should not be interpreted as future policy or as endorsements of participating companies or products.
Two forms of digital money in one workflow
The consortium is exploring whether a cross-border payment can coordinate a stablecoin leg with settlement on the Lab’s simulated digital-pound rails. Polygon says its Open Money Stack supplies orchestration and smart-contract infrastructure for the stablecoin side of the test.
A second workstream, led by NOBO Finance, is examining a portable credit profile for small and medium-sized businesses. Dun & Bradstreet contributes business identity and credit data, while Polygon provides onchain infrastructure. The aim is to test whether payment and credit information can support trade-finance workflows without treating the experimental profile as a production credit product.
For payments firms, the important issue is not whether one digital asset replaces another. It is whether distinct forms of money can be coordinated without creating new reconciliation delays, trapped liquidity or settlement exposure. A merchant or exporter may receive value on one rail while its counterparty funds or settles through another. Connecting those legs requires more than token transfer: operators need clear transaction states, exception handling, compliance controls and responsibility for failures.
What the experiment can establish
The Lab can help participants test messaging, orchestration and settlement logic in a controlled setting. It may also expose where an institution would need common identifiers, synchronized status updates and rules for incomplete or mismatched payment legs.
It cannot yet demonstrate commercial demand, regulatory approval, production resilience or finality with real central bank money. No live digital pound exists, and the experiment does not establish that Polygon, NOBO Finance or Dun & Bradstreet will operate any future UK payment infrastructure.
Those limits make the experiment more useful as a design exercise than as evidence of a launch. If the participants show that stablecoin and simulated central-bank-money legs can be coordinated, the next questions for payment providers will concern governance: who controls the orchestration layer, how compliance data move between parties, what happens when only one leg completes, and which entity bears liquidity and operational risk.
Why the trade-finance setting matters
Cross-border trade often separates shipment, financing and payment across multiple institutions and systems. Smaller businesses can face particular pressure when settlement delays tie up working capital or when lenders lack portable, current information about a prospective borrower.
Testing settlement interoperability alongside a reusable business-credit profile therefore links two practical problems: moving value across different rails and giving finance providers enough verified information to assess a transaction. Whether that combination works outside the Lab will depend on data permissions, liability arrangements, regulatory treatment and integration with existing banking and trade systems.
The Bank of England says Phase 2 will conclude in 2026 and plans a final update after completion. Until then, the project should be read as an early technical experiment—not a commitment to issue a digital pound or deploy a live stablecoin trade-finance service.
