Polygon Expands Regulated Payments Stack to Solana; Kira Signs as First Customer

Polygon has expanded its Open Money Stack to the Solana blockchain, enabling businesses to manage bank funding, wallets, and cross-chain transfers through a single integration. For fintech professionals, this move marks Polygon’s transition from a network provider to a cross-chain payments infrastructure player, leveraging its regulated US status to compete for end-to-end transaction volume.

What was announced

Polygon is integrating its Open Money Stack with Solana, providing a unified infrastructure for businesses to handle bank-to-crypto and crypto-to-bank workflows. This follows the company’s recent addition of TRON support and signals a strategic shift toward chain-agnostic payment services. The stack allows businesses to manage bank funding, customer wallets, and payouts into supported bank accounts and digital wallets within a single framework.

Through its completed acquisition of Coinme, Polygon now operates as a regulated payments business across 48 U.S. states. This regulatory footprint allows the company to facilitate complex financial flows, such as remittance services. For example, a provider can accept dollars from a sender’s bank account, move USDC via the Solana network, and execute a final payout to the recipient’s bank. Polygon is specifically competing for the full payments relationship, covering the entire lifecycle from initial funding through to the final payout, rather than just the transfer on its own chain.

Kira is among the first customers to utilize Solana through the Open Money Stack. The firm uses the infrastructure to bridge U.S. banking and stablecoins for cross-border businesses, allowing clients to move between fiat and digital assets to pay international suppliers. By offering these tools on Solana, Polygon is positioning its stack to serve businesses building on major networks outside of the Ethereum ecosystem.

The companies involved

Polygon is a major player in the blockchain infrastructure space, originally known for its Ethereum scaling solutions. The company has evolved significantly, recently pivoting toward a broader payments identity with the launch of its Open Money Stack. The acquisition of Coinme provided Polygon with the necessary regulatory licenses to operate as a money transmitter in the vast majority of the United States, a rare position for a blockchain-native firm. This allows it to bridge the gap between traditional banking systems and decentralized ledgers.

Solana is a high-performance blockchain known for its speed and low transaction costs, making it a frequent choice for payment applications and stablecoin issuers. It operates as an independent network from Ethereum and Polygon’s own primary chain. The integration of Polygon’s payment tools into Solana highlights the growing interoperability between major networks. While Polygon and Solana are often viewed as competitors for developer talent and liquidity, this move suggests a market reality where infrastructure providers must support multiple ecosystems to remain relevant to global enterprises and remittance providers.

What FF News has reported before

FF News has closely tracked Polygon’s aggressive expansion into regulated financial services. In October 2026, we reported that Polygon Labs Acquires Coinme to Launch Integrated 'Open Money Stack' for Global Payments, a move that laid the groundwork for its current multi-chain strategy. This followed the launch of Polygon Launches Checkout: Seamless Stablecoin Payments for Stripe Merchants, which integrated stablecoin payments for traditional e-commerce.

The Solana ecosystem has also seen significant payment activity recently. We previously covered how Universal Launches UAE-Regulated USDU Stablecoin on Solana with Aquanow Distribution. Furthermore, other infrastructure providers are moving in a similar direction; in September, Morph Payments Adds Solana and TRON to Enable Direct Exchange-to-Merchant Stablecoin Transfers, indicating a broader industry trend toward multi-chain stablecoin support.

What this means

This move shifts the competitive landscape by decoupling blockchain infrastructure from payment processing. Polygon is no longer just defending its own "walled garden"; it is positioning itself as a regulated middleware layer that can sit on top of any high-speed network. This puts pressure on traditional payment processors and crypto-native on-ramp providers who lack either the multi-chain flexibility or the deep regulatory licensing Polygon now possesses. The industry must now ask whether the "network wars" are being superseded by an "infrastructure war," where the winner is not the chain with the most total value locked, but the provider that best hides the underlying complexity of moving money between banks and blockchains.
