Polygon Labs is extending its Open Money Stack to Solana, widening a payments product that already connects bank accounts, crypto wallets and payout rails on Polygon, Ethereum and other Ethereum Virtual Machine networks. The Solana rollout follows the addition of Tron support earlier in October and comes as stablecoin activity continues to concentrate on high-throughput networks. The company says the expansion will let businesses building on Solana accept funding from bank accounts, offer customer wallets and arrange payouts through a single integration.

The announcement places Polygon’s payments infrastructure in direct conversation with one of the busiest stablecoin ecosystems in the market. It also highlights a broader shift in crypto payments: businesses increasingly want to support multiple chains without forcing customers to choose a network or stitching together separate banking, wallet, routing and payout providers.

What Open Money Stack does

Open Money Stack is best understood as an orchestration layer for payments rather than a standalone blockchain. It brings together funding sources, wallet infrastructure and payout networks so that a business can offer crypto-enabled payment flows without building every connection itself. On the funding side, that can include bank accounts, cards and cash. On the customer side, it can include hosted accounts and embedded wallets. On the settlement side, it can include payouts through global networks.

For Solana-based businesses, the practical effect is that a company can accept funding from a bank account, give customers a wallet and arrange payouts without assembling separate vendors for each function. The same integration is intended to support multiple networks, which matters for companies whose users and payment activity are already spread across chains. The stack was already available for eligible uses on Polygon, Ethereum and other EVM networks, and Trails has linked Solana with Ethereum-compatible networks since August.

Why Solana and Tron now

Polygon Labs CEO Marc Boiron said customer demand and stablecoin activity drove the decision to expand to Solana and, earlier this month, Tron. The timing reflects where stablecoin transfers are happening. Token Terminal data cited in the announcement shows Solana recorded about $5.76 trillion in stablecoin transfers between Jan. 1 and Oct. 27, while Tron recorded about $6.94 trillion over the same period. Those are not small niches. They represent two of the largest venues for stablecoin movement, and each has a distinct user base and set of payment corridors.

Tron has long been associated with high-volume stablecoin transfers, particularly in markets where dollar-denominated digital assets are used for remittances and everyday payments. Solana has built a reputation for fast, low-cost transactions and a broad consumer and developer ecosystem. Supporting both networks gives Polygon’s payments customers more ways to reach users without making a binary chain choice. It also acknowledges that payment activity is rarely confined to a single ledger.

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.

Stablecoin volumes shape the decision

The scale of stablecoin transfers helps explain why infrastructure providers are prioritizing multi-chain support. Stablecoins have moved from a niche trading instrument to a core settlement asset for exchanges, remittance providers, merchants and fintech platforms. Businesses that use stablecoins for payouts or collections need reliable access to banking rails, wallet custody and liquidity across the networks their customers prefer. A payments stack that covers only one chain can become a bottleneck when a customer or counterparty uses another.

Solana’s transfer volume also points to a market where speed and cost matter. Payment providers are under pressure to make transactions feel instant and inexpensive while still meeting compliance requirements. Tron’s volume tells a similar story in different corridors. By connecting both networks to bank-account funding and payout services, Polygon is positioning Open Money Stack as a bridge between traditional finance and on-chain settlement rather than as a single-chain wallet product.

From Trails to full-stack payments

Polygon’s Trails service has supported transfers between Solana and Ethereum-compatible networks since August. The latest expansion goes further. It adds access to bank, card and cash funding, customer accounts, embedded wallets and payouts through the same integration, Boiron said. That distinction matters. A transfer tool moves assets from one network to another. A full payments stack handles the surrounding workflow: onboarding, funding, account management, wallet infrastructure, routing and disbursement.

Boiron said businesses have told the company that their customers and payment activity are already spread across networks. They do not want to force a chain choice on users, and they do not want to stitch together a bank provider, wallet, routing service and payout partner for each network. The Solana expansion is designed around that complaint. Instead of asking a business to build separate payment operations for Solana, Polygon and Ethereum-compatible chains, the stack aims to provide a common interface across them.

Regulatory reach after the Coinme acquisition

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. Bank funding, customer accounts and payouts involve money transmission, custody and compliance obligations that vary by jurisdiction. A provider without the right licenses can build a compelling product but still struggle to serve US customers at scale.

The Coinme deal therefore adds more than geographic reach. It gives Polygon’s payments arm a regulated footprint that can support bank-linked funding and payout services across most US states. That footprint is relevant to businesses that want to combine on-chain settlement with traditional account infrastructure. It also raises the bar for competitors that need to assemble similar licensing coverage before they can offer comparable services.

Customer demand and chain fragmentation

Chain fragmentation is one of the central operational problems in crypto payments. A merchant may price in one stablecoin, settle on another network, hold funds in a bank account and pay suppliers in a third currency or chain. Each additional network adds integrations, reconciliation work and compliance checks. The promise of a stack like Open Money Stack is that much of that complexity is abstracted away.

Boiron’s comments suggest that demand is coming from businesses that already operate across networks rather than from users who want to pick a single chain. That is an important distinction. Crypto-native companies may be comfortable managing multiple wallets and bridges, but mainstream businesses want a simpler operating model. They want to know that a customer can fund an account, receive a wallet and get paid without the business rebuilding its back office for every network.

What businesses can do with the Solana integration

With the Solana expansion, eligible businesses can use Open Money Stack to accept funding from bank accounts, provide customer wallets and arrange payouts. The stack can also support card and cash funding, customer accounts and embedded wallets through the same integration, according to the company. For Solana-native projects, that opens the door to banking-style features that are difficult to build in-house. For fintech and payment companies, it offers a way to add Solana settlement without abandoning existing EVM-based operations.

The integration may be particularly relevant for use cases such as remittances, cross-border payouts, merchant settlement and treasury management. In each case, the business needs to move value between traditional accounts and on-chain wallets while keeping the customer experience simple. The Solana network’s throughput and low transaction costs can make those flows more efficient, but the surrounding banking and compliance layer remains essential. Open Money Stack is intended to supply that layer.

Early customer and ecosystem signal

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 presence as an early user is a signal that the product is aimed at companies that combine traditional accounts with on-chain settlement. Kira’s business model depends on moving value across borders efficiently, which makes the combination of bank funding, wallets and payouts a natural fit.

The broader Solana ecosystem has also grown into a sizable market for payment and fintech experimentation. Ecosystem data provider The Grid cataloged 478 companies and 261 projects in the Solana ecosystem last year. That base gives infrastructure providers a reason to support the network directly rather than treating it as a secondary destination. For Polygon, the calculation is not only about Solana’s current stablecoin volume but also about the number of businesses that may want to build payment products on top of it.

Competitive context and market implications

The move reflects a wider competition among payment infrastructure providers to become the default connection point between banks, wallets and blockchains. Stablecoin issuers, custodians, wallet providers and banking-as-a-service platforms are all trying to own parts of the workflow. A product that coordinates those pieces can be more valuable than any single component, especially for businesses that do not want to manage multiple vendors.

At the same time, multi-chain support is becoming table stakes. Payment companies increasingly expect to serve customers across Ethereum, Solana, Tron and other networks without asking users to understand the underlying chain. Polygon’s decision to add Solana after Tron suggests that it sees network coverage as a competitive requirement rather than an optional feature. The company is betting that businesses will prefer a single provider that can route across networks and connect to regulated banking rails.

The rollout also underscores how stablecoin activity influences infrastructure strategy. Networks with large transfer volumes attract payment providers, and payment providers in turn make those networks easier to use for mainstream businesses. Solana’s $5.76 trillion in stablecoin transfers and Tron’s $6.94 trillion over the same period are strong signals that demand exists. The open question is how quickly businesses will migrate from ad hoc multi-vendor setups to integrated stacks that handle funding, wallets and payouts together.

For now, the Solana expansion gives Polygon a broader surface area in stablecoin payments and gives Solana-based businesses a new route to bank accounts and global payout networks. It also adds another front in the contest over who controls the connective layer between traditional finance and on-chain settlement. The next test will be whether businesses use the integration for production payment flows at scale, rather than only for pilots and isolated use cases.
