Polygon Labs on October 29, 2026 extended its Open Money Stack (OMS) payments infrastructure to Solana, making it the sixth blockchain network supported by the platform alongside Polygon, Ethereum, Base, Arbitrum, and TRON. The integration enables enterprises to accept fiat deposits via bank transfer, card, or cash; convert funds into Solana-native USDC, USDT, or PYUSD; and route payments across all six chains through a single API. The move comes 15 days after Polygon completed its acquisition of Coinme, the U.S.-licensed money services business that provides OMS with 37 state money transmitter licenses and 11 applicable exemptions covering 48 states.
The Solana addition is significant for two reasons. First, Solana has processed more than $5.5 trillion in stablecoin volume in 2026, according to Solana Foundation Chief Product Officer Vibhu Norby, with 9.7 million USDC and 3.1 million USDT holder accounts on the network. Second, it signals Polygon's strategic shift from a single-chain protocol to a chain-agnostic payments middleware operator — a model that captures value from cross-network fund flows regardless of which chain carries the settlement.
Polygon Labs completed its acquisition of Coinme on October 14, 2026, a deal first announced in January 2026 as part of a combined $250 million-plus package that also included blockchain infrastructure provider Sequence. Polygon did not disclose Coinme's individual purchase price.
Coinme's value to Polygon is primarily regulatory. The business holds 37 state money transmitter licenses and 11 applicable exemptions, providing coverage across 48 U.S. states. It is registered with the Financial Crimes Enforcement Network (FinCEN) as a money services business. Before the acquisition, any enterprise integrating OMS would have needed to source its own fiat on-ramp and off-ramp partners. Post-acquisition, those capabilities sit inside the same entity that operates the cross-chain routing layer.
The timing matters. The U.S. regulatory environment for stablecoin payments firmed considerably in 2026, with the OCC's GENIUS Act final stablecoin rule and ongoing SEC custody framework proposals creating clearer compliance lanes. Polygon's decision to acquire licenses rather than build or partner for them mirrors a pattern visible across the sector: Bridge (acquired by Stripe for $1.1 billion, received preliminary OCC trust bank approval in February 2026), MoonPay (holds money transmitter authorizations across all U.S. states plus a New York BitLicense), and Zero Hash (51 U.S. state licenses). Regulatory coverage has become a competitive moat.
The Solana integration adds the following capabilities to OMS:
Fiat Deposits: Enterprises can accept U.S. dollar deposits via bank transfer (ACH), debit/credit card, cash at retail locations, or inbound crypto conversion. Funds settle into Solana-native stablecoin balances.
Supported Assets: USDC (Circle), USDT (Tether), PYUSD (PayPal), SOL, and wrapped SOL. Solana currently holds approximately $16.9 billion in total stablecoin supply, led by USDC at $7.2 billion and USDT at $2.9 billion as of early October 2026.
Wallets: Custodial and embedded wallets on Solana, managed through OMS's unified API. Enterprises can provision wallets programmatically for end users without managing Solana key infrastructure directly.
Cross-Chain Routing: Via Polygon Trails, funds held on Solana can be routed to Polygon, Ethereum, Base, Arbitrum, TRON, or Optimism. The routing layer handles conversion and bridging internally, presenting a single settlement interface to the integrating business.
Payouts: Withdrawal to U.S. bank accounts, debit cards, cash outlets, or external crypto wallets. This completes the fiat-in, stablecoin-transit, fiat-out loop without the enterprise needing to manage multiple vendor relationships.
Solana Foundation CPO Vibhu Norby stated that OMS "provides another path for businesses to access these capabilities, complementing the infrastructure and payment solutions already available" on Solana.
The pace of OMS chain additions has accelerated:
| Date | Event | |------|-------| | January 8, 2026 | OMS unveiled as modular stablecoin payments framework | | October 8, 2026 | TRON support added (connecting $94B USDT ecosystem) | | October 14, 2026 | Coinme acquisition completed (48-state coverage) | | October 29, 2026 | Solana support added ($5.5T stablecoin volume in 2026) |
The TRON-to-Solana gap was 21 days. TRON's addition was strategically oriented toward USDT remittance corridors — TRON carries the single largest concentration of USDT supply globally, with over $94 billion in circulating TRC-20 USDT. Solana's addition targets a different segment: high-velocity payment applications and the network's growing USDC and PYUSD ecosystems.
Early enterprise customers include Tazapay (cross-border B2B payments), Mesh (payment orchestration), Toku (crypto payroll and compensation), and Kira (cross-border transfers). Kira CEO Edrizio De La Cruz noted the integration helps "turn those transfers into dollars in our clients' bank accounts when they need to pay suppliers." None have disclosed transaction volumes through OMS.
Lily Liu, President of the Solana Foundation, characterized the integration by saying she felt "unblocked" by the addition — a reference to the difficulty Solana-based businesses previously faced in accessing regulated U.S. fiat rails without assembling multiple vendor stacks independently.
Polygon is not the only entity assembling a vertically integrated stablecoin payments stack. The competitive field has consolidated rapidly in 2026:
Bridge (Stripe): Acquired by Stripe for $1.1 billion (completed February 2025). Received preliminary OCC conditional approval for Bridge National Trust Bank in February 2026. Luxembourg-authorized crypto-asset service provider under MiCA. Operates as Stripe's embedded stablecoin infrastructure layer for accepting, holding, moving, and issuing stablecoins.
MoonPay: Launched MoonPay Enterprise on August 6, 2026, unifying collection, conversion, treasury, issuance, and payouts into a single platform. Holds money transmitter authorizations across all U.S. states, a New York BitLicense, European MiCA authorization, and registrations in the UK, Canada, and Australia.
BVNK (Mastercard): Mastercard announced its acquisition of BVNK for up to $1.8 billion in March 2026. BVNK provides stablecoin payment orchestration for enterprise clients. The deal signals that legacy card networks view stablecoin routing as core infrastructure.
Zero Hash: Holds 51 U.S. state money transmitter licenses — the deepest regulatory footprint among crypto-native payment processors. Operates as embedded infrastructure for fintechs to offer crypto and stablecoin services.
The common pattern: each player is assembling four layers — regulatory licenses, fiat connectivity, multi-chain stablecoin routing, and programmable payout rails — into a single API. The differentiation is narrowing to coverage breadth (how many chains, how many jurisdictions) and pricing.
Polygon's OMS model represents a structural shift in how a Layer 1/Layer 2 protocol captures economic value. Traditional L1 revenue models depend on transaction fees paid by users of that specific chain. Polygon's gas fee revenue from its own network totaled approximately $79 billion in monthly stablecoin volume in 2026 — but the OMS model generates revenue from cross-chain routing, fiat conversion spreads, and custody services regardless of whether the stablecoin transaction settles on Polygon's own network.
This is a departure from the protocol-fee model that dominates most blockchain economic analysis. When a business uses OMS to route a payment from a U.S. bank account through USDT on TRON to a supplier's bank account in another country, Polygon extracts value from the orchestration and compliance layer — not from TRON's gas fees. The protocol becomes an infrastructure operator rather than a settlement layer.
The model's viability depends on volume. Polygon's own network has carried over $3 trillion in stablecoin transfers, with $741 billion moved in 2026 through September. However, OMS volume from enterprise customers has not been disclosed. The four named early adopters — Tazapay, Mesh, Toku, and Kira — are mid-market businesses. Whether OMS can attract the volume required to justify the Coinme acquisition cost and ongoing compliance overhead remains an open question.
The broader stablecoin payment infrastructure market is projected to reach $409 billion in 2026, growing at a 26.9% compound annual rate, according to industry estimates. In 2025, stablecoins processed approximately $46 trillion in total transaction volume — more than 20 times PayPal's annual volume.
Polygon's addition of Solana to Open Money Stack completes a rapid three-week expansion that took the platform from four to six supported chains. Combined with the Coinme acquisition, Polygon now operates a regulated, multi-chain stablecoin payments stack with fiat connectivity across 48 U.S. states — a capability that did not exist at this scope from a single crypto-native provider at the start of 2026.
The competitive implications are clear: the stablecoin payments infrastructure layer is consolidating around a small number of operators who combine regulatory licenses, multi-chain routing, and programmable payouts. Stripe, Mastercard, MoonPay, and now Polygon are each spending hundreds of millions to assemble these stacks. The differentiation window is narrowing.
For Polygon specifically, the open question is whether this middleware positioning generates sufficient revenue to justify the pivot. The protocol's own chain processes $79 billion in monthly stablecoin volume, but OMS enterprise adoption data remains sparse. The infrastructure is built. The volume has yet to follow.
