Phase 2 of the BOE's Digital Pound Lab tests stablecoin settlement with Polygon and portable credit profiles for SMEs. Findings will feed into the Treasury's digital pound assessment later this year.
The Bank of England is testing whether stablecoins and a digital pound can run in the same payment pipeline for trade finance, moving its Digital Pound Lab into a second phase Wednesday.
The experiment involves NOBO Finance, Dun & Bradstreet, and Polygon Labs. NOBO builds digital trade infrastructure for small and medium-sized enterprises. Dun & Bradstreet provides business credit data. Polygon runs the software layer for stablecoin settlement.
Central banks globally are trying to reconcile private stablecoins – crypto tokens pegged to fiat – with state-issued digital currencies. The BOE's work focuses on trade finance, a process that still relies on paper documents and can take days. Small businesses are hit hardest by those delays, said Otto Jacobsson, U.K. chapter lead at the Digital Assets Association.
“If these processes can become faster and more efficient, U.K. businesses could unlock working capital sooner and make it easier to finance international trade,” Jacobsson said in an interview over LinkedIn.
The Digital Pound Lab uses no real customers or money. It is a sandbox, not a commitment to issue a digital pound. The BOE has been experimenting with distributed-ledger technology since 2024.
Phase 1, with NOBO already involved, demonstrated conditional business-to-business escrow payments for trade workflows. Phase 2 goes further.
One workstream will build an SME “bankable profile.” NOBO, Dun & Bradstreet, and Polygon plan to combine wallet transaction data, open-finance information, and business intelligence into a reusable credit assessment. Polygon will supply smart contracts to record the verified outcome and manage consent.
A second workstream tests invoice factoring backed by electronic bills of lading. An exporter would receive an advance via stablecoin, while a U.K. importer settles in digital pounds.
“For digital money to actually move the world’s trade, its different forms have to work together – public and private, central bank money and stablecoins,” Marc Boiron, CEO of Polygon Labs, said in a statement. “This experiment tests exactly that.”
Polygon is providing its Open Money Stack for stablecoin settlement, including fiat-to-stablecoin conversion, wallets, and smart contracts.
The findings will feed into the BOE and Treasury’s joint assessment of the digital pound ahead of next steps later this year. The broader question is whether different forms of digital money can interoperate, instead of forcing companies and customers onto a single payment infrastructure.
“Cross-border SME trade finance is still slowed by fragmented verification, manual checks, and settlement that can take days,” the group said in a statement. “For small businesses, the gap between shipping goods and receiving payment is frozen capital.”
