Polygon Labs has expanded its Open Money Stack, a suite of services that connects bank accounts, crypto wallets and payout networks, to the Solana blockchain. The integration allows businesses building on Solana to accept funding from bank accounts, provide customer wallets and arrange payouts through a single set of tools. The move is designed to reduce the operational friction that comes with stitching together separate banking, wallet, routing and payout providers for each blockchain a company supports.

The Solana rollout follows the addition of Tron support earlier in October and comes after Polygon completed its acquisition of Coinme. That deal gave its US payments business access to 37 money transmitter licenses and 11 state exemptions, covering 48 states. The combination of a multi-chain payments stack and a broader licensing footprint is central to Polygon’s effort to serve businesses that want to move between fiat money and stablecoins without forcing customers to choose a single network.

Key facts at a glance

• Polygon Labs has extended Open Money Stack to Solana after adding Tron support.
• Businesses on Solana can use the stack for bank-account funding, customer wallets and payouts.
• 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 industry data.
• Polygon’s acquisition of Coinme added 37 money transmitter licenses and 11 state exemptions, covering 48 states.
• Polygon’s Trails service has supported transfers between Solana and Ethereum-compatible networks since August.
• Kira, a provider of US dollar accounts and stablecoin-based cross-border payment services, is among the first customers using the Solana integration.

Polygon Labs CEO Marc Boiron said customer demand and stablecoin activity drove the decision to expand to Solana and, earlier in October, to Tron. The company is betting that payment flows will not be confined to a single chain and that infrastructure providers must be able to route value across networks while keeping the user experience simple.

Vibhu Norby, chief product officer at the Solana Foundation, said the connection between Solana and bank accounts, wallets and global payout networks would help businesses deliver stablecoin payments to more customers and markets as activity grows. The comment reflects a broader shift in crypto payments: stablecoins are increasingly treated as settlement rails for cross-border transfers, merchant payouts, payroll, remittances and treasury operations rather than as trading instruments alone.

Why Solana and Tron are central to the payments strategy

Stablecoin transfers have become one of the clearest product-market fits in digital assets. Businesses use dollar-denominated tokens to move value across borders quickly, and they often choose networks based on liquidity, cost and the preferences of their counterparties. Solana has built a reputation for high throughput and low transaction fees, which can be attractive for high-frequency payment flows. Tron has developed a large base of stablecoin transfer activity, particularly in markets where dollar access and cross-border settlement are pressing needs.

The scale is significant. 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 industry data. Those figures help explain why Polygon is not limiting its payments stack to its own network or to Ethereum-compatible chains. The company is instead treating Open Money Stack as an orchestration layer that can sit above multiple settlement networks and connect them to familiar financial rails.

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, Boiron said. That means a business can offer a customer a dollar account or wallet, accept funds from a bank account or card, and send payouts to a recipient in another market without building separate integrations for each chain and each financial partner.

A single integration for fragmented payment rails

The problem Open Money Stack is trying to solve is fragmentation. A fintech building a cross-border payments product might need a banking partner for deposits, a wallet provider for custody, a routing service for blockchain transactions, a liquidity provider for conversions and a payout partner for local disbursement. Each provider may support different chains, different countries and different compliance requirements. Maintaining those connections can slow product launches and increase operational risk.

Boiron said businesses report that their customers and payment activity are already spread across networks, and that they do not want to force a chain choice or stitch together a bank provider, wallet, routing service and payout partner for each one. The expanded stack is intended to let them use one integration while giving end customers more options for how they fund accounts and receive money.

The broader stack was already available for eligible uses on Polygon, Ethereum and other Ethereum Virtual Machine networks. By adding Solana and Tron, Polygon is extending the reach of that model to two networks that account for a large share of stablecoin transfer activity. The approach also allows Polygon to participate in payment flows that may never touch its own chain, as long as they pass through infrastructure it operates or connects.

Coinme deal adds regulatory reach

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. Licensing is a critical but often underappreciated part of crypto payments. Businesses that move fiat money on behalf of customers must navigate state-by-state money transmission rules, anti-money-laundering obligations, know-your-customer checks and record-keeping requirements. A broad licensing footprint can shorten the path to market for products that combine bank accounts with stablecoin settlement.

Polygon has framed the Coinme deal as a way to strengthen its US payments business. The acquisition does not by itself make every product available in every state or resolve all regulatory questions, but it gives the company a more substantial compliance base from which to support partners. That base matters for Open Money Stack because bank funding, customer accounts and payouts all depend on regulated financial infrastructure, not only blockchain software.

The combination of licensing and multi-chain connectivity could appeal to fintechs, remittance providers, merchants and marketplaces that want to offer stablecoin payments without becoming experts in every network. It could also appeal to crypto-native companies that want to add fiat on-ramps and off-ramps while keeping their existing wallet and settlement arrangements.

Solana’s ecosystem and early customers

Solana’s ecosystem is substantial. In one prior-year catalog, an ecosystem data provider counted 478 companies and 261 projects building on the network. That breadth matters for payments infrastructure because it creates demand from wallets, exchanges, payment apps, marketplaces and other services that need funding and payout tools. Boiron said Kira, which provides US dollar accounts and stablecoin-based cross-border payment services to businesses, is among the first customers using the Solana integration.

Kira’s use case illustrates the kind of product Open Money Stack is targeting. Businesses that need dollar accounts and cross-border payments often want to combine traditional banking access with stablecoin settlement. They may need to collect funds in one currency, convert them, hold them in a wallet and pay out to recipients in another market. A stack that connects bank accounts, embedded wallets and payout networks can reduce the number of vendors involved and make the flow easier to manage.

The Solana integration also builds on existing cross-chain work. Since August, Trails has allowed transfers between Solana and Ethereum-compatible networks. The new services add more of the financial workflow around those transfers: where the money comes from, where it is held and how it reaches the recipient. That broader scope is what distinguishes a payments stack from a simple bridge or routing tool.

What the expansion means for businesses

For businesses, the practical effect is that a single technical integration can support multiple funding methods and multiple settlement networks. A company could let a customer fund an account from a bank, hold a balance in a wallet, send a stablecoin payment over Solana or an EVM network, and arrange a payout through local rails. The business would not need to force the customer to understand which chain is being used at each step.

That kind of abstraction is becoming more important as stablecoin competition increases. Different networks have different strengths: some offer low fees and fast confirmation, some have deep liquidity, some are preferred in particular regions and some are more compatible with existing Ethereum tooling. A payments provider that can route across networks may be better placed to serve global customers than one that relies on a single chain.

There are still challenges. Regulatory requirements vary by jurisdiction, and money transmission licensing is only one part of the compliance picture. Blockchain congestion, wallet security, liquidity sourcing and customer support also affect payment reliability. Businesses will need to evaluate which corridors, assets and networks are supported for their specific use cases, and they will remain responsible for their own compliance programs.

Even so, the direction of travel is clear. Payment infrastructure is becoming multi-chain, and stablecoins are moving deeper into mainstream financial workflows. Polygon’s expansion to Solana, following its Tron rollout and Coinme acquisition, shows how infrastructure providers are trying to connect bank accounts, wallets and payout networks across the networks where customers already operate. Kira is among the first customers using the Solana integration, and the broader stack remains available for eligible uses on Polygon, Ethereum and other EVM networks.
