Polygon Labs adds Solana to open money stack

Polygon Labs has connected Solana to its Open Money Stack, giving businesses another route to combine U.S. dollar bank accounts, stablecoin transfers, blockchain settlement and payouts through a single integration. The addition places Solana alongside Ethereum and TRON in Polygon Labs' payments platform, which is aimed at companies moving funds between traditional banking systems and onchain networks.

Polygon Labs said the Solana connection would let a business pull money from a bank account, convert or transfer value on a supported blockchain, and pay recipients through bank accounts, cards, cash services or crypto wallets. The model is designed for payment providers and businesses that need to handle both dollar-based transactions and blockchain transfers without building separate connections for each network or payout method.

Kira, a company that supports movement between dollars and stablecoins, is among the first customers using the Solana integration, according to Polygon Labs. Kira also facilitates bank-rail payments and supplier disbursements across borders, putting the new connection to use in an area where companies often face fragmented payment routes, conversion steps and settlement processes.

Solana's faster settlement enters a payments stack

The integration follows Solana's Alpenglow consensus upgrade, which Polygon Labs said was activated roughly a week earlier. The company said the upgrade reduced Solana transaction finality, the point at which a transfer is considered settled and difficult to reverse, from about 12.8 seconds to 150 milliseconds.

That claimed reduction would make a meaningful difference for payment products that need quick confirmation before releasing goods, crediting balances or triggering another leg of a transfer. Payment systems do not always require sub-second blockchain finality, particularly for cross-border business disbursements, but faster confirmation can simplify the user experience for point-of-sale, wallet and account-to-account products.

Vibhu Norby, chief product officer of the Solana Foundation, said the network processed more than $5.5 trillion in stablecoin volume during 2026. Norby linked that activity to demand for payment systems that connect onchain transfers with offchain destinations such as bank accounts and local payout services.

A high-volume blockchain alone does not resolve the operational hurdles of sending money to a supplier, contractor or customer. The recipient may need local currency, a card payout, a bank deposit or cash collection rather than a crypto wallet. Polygon Labs' Open Money Stack is built around that conversion and routing layer, seeking to join blockchain liquidity with the endpoints businesses already use.

Stablecoin payment demand drives network connections

The expansion arrives as dollar-pegged stablecoins remain a major source of onchain transaction activity. Figures supplied with the announcement placed the total supply of U.S. dollar-pegged stablecoins near $290 billion, led by USDT with more than $182 billion in supply and USDC with almost $76 billion.

Supply figures show the amount of tokens in circulation, rather than the value of payments settled or the number of active users. Yet their scale helps explain why payments companies are increasingly focused on stablecoins instead of treating them solely as trading instruments. A dollar-denominated token can move at blockchain speed while retaining a unit of account that companies already use for payroll, invoicing and supplier payments.

Polygon Labs' approach does not rely on a single blockchain winning all payment flows. By supporting Ethereum, TRON and Solana, the company is positioning the Open Money Stack as a routing layer for businesses whose customers, treasury balances or payout partners are spread across different networks.

TRON was added earlier in October, according to Polygon Labs. Its inclusion matters for stablecoin payments because USDT has long had a substantial presence on the network, particularly in transfer corridors where users prioritize low costs and broad wallet support. Solana brings a different profile, an emphasis on high throughput and faster confirmation times following the Alpenglow upgrade.

For a payments company, supporting multiple chains can reduce the need to force customers into one ecosystem. A business may receive stablecoins on one network, hold balances in another format, and pay a recipient through a banking or card channel. The operational challenge is managing those movements while keeping fees, compliance processes and reconciliation manageable.

Coinme deal expands Polygon Labs' U.S. payments reach

The Solana connection follows Polygon's completed acquisition of Coinme earlier this month. Polygon Labs said the transaction added money-transmission licenses and exemptions spanning 48 U.S. states, expanding its regulated payments footprint in the country.

Those state-level permissions could give the company greater control over the regulated parts of a payment flow involving fiat currency, rather than depending entirely on outside providers for account funding, dollar conversion and customer payouts. The acquisition also connects Polygon Labs' blockchain infrastructure with Coinme's established compliance and money-transmission operations.

State money-transmission requirements vary, and their relevance depends on the services offered, the location of customers and the way funds are handled. For companies building payment products, licenses can be as consequential as network integrations because they determine which parts of a transaction can be operated directly and which must be handled by a regulated partner.

The combined strategy is increasingly clear, Polygon Labs is assembling both the blockchain connections and the regulated payment infrastructure needed to move funds across bank rails, stablecoins and payout networks. Solana adds a faster settlement option to that system, while Coinme gives the company a larger U.S. licensing base for the dollar side of transactions.

Kira's early use of the integration will offer a practical test of whether that combination can reduce friction for cross-border supplier payments and similar commercial flows. The strongest measure will be whether businesses can move from a bank-funded payment to a recipient's preferred destination with fewer intermediaries and less operational complexity.
