Polygon Labs has added Solana to its Open Money Stack, giving businesses on the blockchain access to banking and stablecoin payment services through a single connection. The rollout links two networks that have competed for users and developers, and both blockchains will continue operating as separate platforms.

Through the integration, companies can accept money from several funding sources, create digital wallets, move digital assets between networks, and pay recipients through supported providers. Solana-based businesses can plug into banking services and global payment options without migrating their applications, keeping their products on Solana while relying on Polygon’s payment tools.

Bank Payments Meet Stablecoin Rails

Businesses can take deposits through bank transfers, cards, cash, or cryptocurrency. The Open Money Stack can also convert dollars into stablecoins — blockchain tokens pegged to traditional currencies such as the US dollar — move supported tokens across blockchains, and send funds to bank accounts or wallets. It supports the USDC, USDT, and PYUSD stablecoins. Taken together, those features cover the full path a payment can travel: from a customer’s bank account or card onto blockchain rails, across networks if needed, and back out to a recipient’s bank account or wallet.

The agreement leaves both blockchains separate. “Businesses shouldn’t have to rebuild their payments infrastructure for every network,” Aishwary Gupta, Polygon Labs’ global head of business, told CoinDesk.

Banks Test More Stablecoin Services

The announcement follows a USDC settlement test in Colombia. Circle, the issuer of USDC, and ACI Worldwide said on October 27 that they would examine how banks could use stablecoins alongside current payment systems.

Solana has processed more than $5.7 trillion in stablecoin transfers in 2026, according to Jamal Raees of the Solana Foundation. Polygon reports more than $3 trillion in transfers since launch. These totals include wallet transfers. The figures indicate the scale of activity each network brings to the arrangement.

Kira is among the first companies using the new integration. The cross-border payment provider transfers stablecoins on Solana and uses Polygon’s banking connections to help customers make dollar payments to suppliers outside their home markets. The arrangement illustrates how the integration works in practice.

Other banks are introducing digital payment products as well. HSBC recently launched a Hong Kong dollar stablecoin on PayMe, the bank’s Hong Kong payments app, with plans to support transfers between users and payments to merchants. The moves are part of a broader wave of stablecoin initiatives spanning banks, payment companies, and blockchain networks.

Polygon Widens Its Payment Network

Polygon recently brought TRON into the Open Money Stack and completed its acquisition of Coinme, a United States crypto payments company. The purchase added licensed money transfer services across 48 states, according to Polygon.

Meanwhile, Visa reported more than $25 billion in annualized stablecoin settlement during its October earnings update. Its expanding card programs show how payment companies are adding blockchain services to existing systems.

Polygon says businesses can use the full service or select individual features, including wallets, transfers, and cash payouts, depending on their needs. The company plans to support additional blockchain networks over time, while Solana businesses can continue using their existing applications. Which networks are added next will show how far the single-connection model extends beyond Solana and TRON.
