Polygon to Launch U.S.-Compliant Payments Platform Using the Open Money Stack

• Polygon to acquire Coinme and Sequence to build a U.S.-compliant stablecoin payments stack.
• Polygon says Coinme operates in 48 states and supports 50,000+ fiat-to-crypto retail locations

Polygon Labs has signed definitive agreements to acquire Coinme and Sequence as it builds a U.S.-compliant payments platform based on stablecoins and blockchain rails. The company dubs it the Polygon Open Money Stack, a vertically integrated set of services aimed at regulated money movement and easier access to crypto-based payments.

In a post on X, Polygon said the two acquisitions are intended to move “all money on-chain,” pairing regulated fiat access with wallet infrastructure and one-click, cross-chain transactions. Polygon stated that Coinme operates in 48 U.S. states and supports over 50,000 fiat-to-crypto retail locations, while Sequence will provide wallet and transaction orchestration tools.

Earlier this month, CNF reported that Polygon is pushing a long-term vision to move global money movement on-chain through its newly launched Open Money Stack. The initiative combines blockchain rails, wallet infrastructure, compliance tools, and earning mechanisms into a single framework to make transfers seamless and interoperable across borders, chains, and apps. 

Coinme and Sequence Add Regulated Rails and Wallet Infrastructure to Polygon

Polygon said the combined price for Coinme and Sequence topped $250 million, though it hasn’t disclosed what it paid for each acquisition. Polygon CEO Marc Boiron noted that the near-term focus is business-to-business payments, with plans to expand to consumer services later, and that the company expects to work with existing payment networks through partnerships.

Polygon said Coinme will contribute U.S.-licensed fiat on- and off-ramps, including money-transmitter coverage and a licensed wallet infrastructure. The company also pointed to Coinme’s existing user base and enterprise APIs as components that can help banks, fintech firms, and merchants connect stablecoin flows to traditional payment routes.

Sequence, which started as a gaming-focused startup before expanding into developer tooling, will be used to simplify onboarding and execution for on-chain payments. The firm said Sequence’s smart wallet infrastructure and “1-click” cross-chain transaction capabilities are intended to reduce the need for end users to manage bridges or multiple steps when moving value across networks.

Moreover, the Open Money Stack is designed to combine fiat entry and exit, wallet creation, and cross-chain routing in a single product set for regulated stablecoin payments. The company described the objective as enabling instant money movement for businesses and consumers while keeping compliance requirements embedded in the stack.

Polygon has positioned stablecoin payments as a core use case as more firms explore dollar-pegged tokens for settlement and payouts. The project views the acquisitions as a way to bring key pieces of payments infrastructure in-house at a time when stablecoin transaction tooling remains spread across multiple vendors.
