Former Rivals Polygon and Solana Partner to Connect Stablecoins to Banks

Polygon Labs and Solana are partnering to connect stablecoin transfers on Solana with Polygon’s banking and payments infrastructure, giving businesses access to both networks without requiring them to choose between rival blockchains. The agreement reflects growing demand from banks and payment companies for stablecoin-based settlement and cross-border transfers.

A Bridge Between Blockchains and Banks

The partnership does not merge Polygon and Solana or change how either blockchain operates. Instead, businesses can continue transferring stablecoins on Solana while using Polygon’s Open Money Stack to access bank funding, digital wallets, cross-chain transfers and payouts.

Jamal Raees, general manager of payments at the Solana Foundation, said the arrangement allows companies to use Polygon’s regulated payment services without leaving Solana. The model is designed to place blockchain settlement and traditional financial rails within a single business integration.

Businesses using Open Money Stack can access services including:

• Bank transfers, card payments and cash through supported providers.
• Customer wallet creation and digital-asset management.
• Transfers between blockchains.
• Payouts to bank accounts and other payment destinations.

The infrastructure is aimed primarily at companies that need to move money across crypto networks and the banking system, rather than at retail users choosing between tokens or trading venues.

Kira Tests the Payments Model

Cross-border payments company Kira is among the first users of the integration. Kira uses Solana for stablecoin transfers and Polygon’s banking connections to help customers pay overseas suppliers in dollars.

That setup separates the functions of the two networks. Solana handles the movement of stablecoins, while Polygon’s infrastructure connects those transactions with bank accounts and payment services. For businesses, the arrangement could reduce the need to build separate integrations for blockchain transfers, wallets and traditional payouts.

The companies are entering the partnership as financial institutions increase their interest in stablecoins for transfers and settlement. Polygon and Solana have historically competed for blockchain activity, but the agreement treats their networks as complementary infrastructure for business payments.

Reported activity underscores the scale of the systems involved, although the figures include wallet transfers and are not limited to payments for goods and services:

• Solana: More than $5.7 trillion in stablecoin transfers so far this year, according to Raees.
• Polygon: More than $3 trillion in total transfers since launch.

What This Means

The partnership may strengthen Solana’s position as a settlement network for businesses that also need access to banks, while giving Polygon a route to customers transacting on a competing chain. Its significance is less about a technical merger than about interoperability between stablecoin rails and regulated payment services.

If additional payment firms adopt the model, businesses could gain more flexibility to select a blockchain for transfers while retaining familiar banking connections for funding and payouts. That could support wider institutional use of stablecoins, provided the integrations can meet compliance, reliability and cross-border payment requirements.
