Polygon is joining the Bank of England's Digital Pound Lab to test stablecoin settlement infrastructure, working alongside NOBO Finance and Dun & Bradstreet on cross-border payment flows, according to the company's announcement.

The consortium will use a simulated test environment to explore how stablecoins and a Bank of England-issued digital pound could settle against each other with reduced friction between different forms of digital money. Polygon will provide smart contract infrastructure for the stablecoin settlement leg, while the Bank's digital pound side runs on test rails with no exposure to real customer funds or live markets.

The Digital Pound Lab represents the Bank of England's second phase of exploration into a potential central bank digital currency for the UK. The test focuses on a narrow use case: how a CBDC could interoperate with private stablecoins in cross-border transactions rather than replacing cash or retail payments. The consortium model allows the Bank to conduct technical trials without building the full infrastructure itself.

Polygon's role centers on the smart contract layer that would execute the stablecoin leg of any settlement. This is distinct from the Bank's own digital pound simulation, which runs separately. The structure lets each party operate within its own risk and regulatory boundary while testing integration points.

Cross-border settlement today fragments across multiple networks and asset types. A stablecoin holder moving value internationally must currently use separate rails for the stablecoin transfer and any fiat conversion or CBDC bridging. The consortium is testing whether these could settle atomically in a single transaction.

The trial is non-binding and excludes live customers, meaning the consortium can fail or redesign without operational risk. The Bank has run similar exploratory consortia before, most recently on tokenized assets and wholesale settlement.

Polygon's participation shows how blockchain infrastructure vendors are engaging with official monetary institutions. Rather than positioning Ethereum-layer scaling as a replacement for traditional finance, projects are now building the interoperability primitives that regulators and banks expect to operate alongside CBDCs. The test does not commit the Bank of England to adopting any particular chain or stablecoin standard; it maps technical requirements and feasibility.
