Polygon Labs is extending its Open Money Stack to Solana, widening a payments product that connects bank accounts, crypto wallets and payout networks beyond Polygon and Ethereum-compatible chains. The expansion follows the addition of Tron support earlier in October and comes as businesses seek to handle stablecoin payments across multiple networks without forcing customers onto a single blockchain.
Open Money Stack is designed as an infrastructure layer for companies that want to offer embedded payments. On Solana, businesses can use it to accept funding from bank accounts, provide customer wallets and arrange payouts. The same integration is intended to reduce the need to stitch together separate banking providers, wallet vendors, routing services and payout partners.
What the Solana Expansion Adds
The Solana integration gives developers and payment companies access to bank, card and cash funding, customer accounts, embedded wallets and payouts through a single connection. That matters for businesses that want to serve customers who may hold funds in bank accounts, stablecoins or local payment rails, rather than in a single form of money.
Marc Boiron, CEO of Polygon Labs, said customer demand and stablecoin activity drove the decision to expand to Solana and, earlier in October, to Tron. The company is positioning Open Money Stack as a way for businesses to deliver payment services across networks while keeping the operational complexity behind a single interface.
The timing reflects the scale of stablecoin movement on both networks. Solana recorded about $5.76 trillion in stablecoin transfers between Jan. 1 and Oct. 27, while Tron recorded $6.94 trillion over the same period, according to Token Terminal data. Those figures show that stablecoin payments are no longer concentrated only on Ethereum and its rollups; high-throughput networks have become major settlement venues for dollar-denominated transfers.
Vibhu Norby, chief product officer at the Solana Foundation, said that as activity grows, connecting Solana to bank accounts, wallets and global payout networks allows businesses to deliver stablecoin payments to more customers and markets. The message is that Solana is not only a venue for trading or decentralized finance, but also a settlement layer that payment companies want to plug into.
Why Stablecoin Activity Is Driving the Decision
Stablecoins have become one of the most visible uses of public blockchains because they combine dollar-denominated value with near-instant settlement and programmable transfer rules. For payment businesses, the appeal is straightforward: a customer can fund an account from a bank, convert to a stablecoin, move value across borders and cash out through a local payout partner. Each step requires different infrastructure, and managing those pieces separately across multiple blockchains can be costly.
Solana and Tron have attracted large stablecoin volumes for different reasons. Tron has built a deep base of stablecoin transfers, especially in markets where dollar access and cross-border payments are in demand. Solana has pursued high throughput and low transaction costs, making it attractive for payment applications, wallets and consumer-facing crypto products. Together, their activity levels explain why a payments stack that once focused on Polygon and Ethereum Virtual Machine networks is now widening its reach.
Boiron said businesses have reported that their customers and payment activity are already spread across networks, and that they do not want to force a chain choice or assemble a separate bank provider, wallet, routing service and payout partner for each network. That comment captures a broader shift in crypto payments: the blockchain is increasingly treated as an execution environment, while the customer experience is expected to feel like a normal financial account.
Trails and the Multi-Chain Payments Thesis
Polygon’s Trails service has supported transfers between Solana and Ethereum-compatible networks since August. The latest expansion adds access to bank, card and cash funding, customer accounts, embedded wallets and payouts through the same integration. In practice, that means a business can use one relationship to manage funding, custody-like wallet services and disbursement across multiple ecosystems.
The broader Open Money Stack was already available for eligible uses on Polygon, Ethereum and other Ethereum Virtual Machine networks. Extending it to Solana and Tron turns the product into a more complete multi-chain offering. Instead of asking customers to choose a network before they can pay, businesses can route value through the networks that best fit their cost, speed and liquidity needs.
That approach also reflects the reality of stablecoin liquidity. Different networks have different strengths, user bases and payout corridors. A payment company may prefer one chain for low-cost transfers, another for liquidity, and another for integration with decentralized applications. Open Money Stack aims to abstract those choices while still giving businesses access to the underlying settlement networks.
Regulatory Reach After Coinme
The Solana expansion follows Polygon’s completed acquisition of Coinme, which gave its US payments business access to 37 money transmitter licenses and 11 state exemptions, covering 48 states. Those licenses are important because payments that touch bank accounts, cash and money transmission often require state-by-state compliance in the United States.
For crypto payment companies, regulatory infrastructure can be as important as blockchain throughput. A product that connects bank accounts to wallets and payouts must navigate know-your-customer checks, anti-money-laundering controls, money transmission rules and consumer protection obligations. Acquiring an established licensed business can shorten the path to operating in multiple states, though it also brings compliance costs and oversight.
The combination of Open Money Stack and Coinme’s licensing footprint suggests Polygon Labs is building toward a payments business that can serve both crypto-native companies and more traditional fintech customers. The Solana integration adds another settlement network to that strategy, while the licenses provide a foundation for serving US customers where money transmission rules apply.
Customer Demand and Early Users
Kira, which provides US dollar accounts and stablecoin-based cross-border payment services to businesses, is among the first customers using the Solana integration. Its use case fits the broader thesis: businesses want dollar accounts and cross-border payment services without having to manage separate infrastructure for every blockchain their customers use.
Last year, ecosystem data provider The Grid cataloged 478 companies and 261 projects in the Solana ecosystem. That base of developers, wallets and payment applications gives Open Money Stack a sizable set of potential integrators. The expansion is not only about adding a network logo to a product page; it is about giving Solana builders access to banking and payout rails that can sit behind consumer and business applications.
For Polygon Labs, the move also strengthens its position as a payments infrastructure provider beyond its own chain. By supporting Solana and Tron, the company can compete for business from teams that are network-agnostic and want a single provider for funding, wallets and payouts. That positioning could become more valuable as stablecoin payments grow and as more fintech companies explore crypto settlement.
Adoption and Integration Questions
The key question is how quickly businesses will use the Solana integration for production payments rather than pilots. Open Money Stack already has a presence on Polygon, Ethereum and other EVM networks, but Solana and Tron require different technical and operational expertise. Supporting them well means maintaining reliable connections to bank funding, wallet infrastructure and payout partners across jurisdictions.
Another question is how much fragmentation businesses are willing to tolerate. Multi-chain support can reduce the need to force customers onto one network, but it can also increase operational complexity if each network has different compliance, liquidity and settlement characteristics. Open Money Stack is designed to hide some of that complexity, but payment companies will still need to manage risk, reconcile transactions and monitor network conditions.
The stablecoin numbers explain why the expansion is happening now. Trillions of dollars in transfers across Solana and Tron show that demand exists for fast, low-cost dollar movement. The next signal will be how many payment businesses use Open Money Stack to connect that activity to bank accounts, wallets and payout networks, and whether multi-chain payment infrastructure becomes the default for stablecoin-powered commerce.
