Polygon Extends Stablecoin Payment Stack to Solana

Solana and Polygon have competed for blockchain activity; on Oct. 29, Polygon Labs announced that its Open Money Stack now supports Solana, connecting bank funding, stablecoin transfers and payouts for businesses. Polygon’s announcement says the service is live. The integration lets businesses build around Solana while using Polygon’s infrastructure for the fiat and payment steps that connect onchain balances to bank accounts.

How does the integration move money?

Polygon says Open Money Stack can handle the payment path from a bank deposit to a Solana stablecoin balance and back to a payout. Businesses can accept funds by bank transfer, card, cash or crypto, convert fiat to crypto on Solana, hold funds in custodial or embedded wallets, and pay out to bank accounts, cards, cash or wallets.

The stack also provides virtual accounts for incoming transfers and programmable accounts through embedded wallets. Polygon says those Solana wallets use the same API as its EVM wallets. Its fiat on- and off-ramps are backed by money transmitter licenses across 48 U.S. states, according to the announcement.

Which assets and networks can it route?

Open Money Stack supports USDC, USDT, PYUSD, SOL and wrapped SOL for routing between Solana, TRON and EVM chains, Polygon said. That can allow an app to accept an asset on one network and settle in another—for example, taking USDC from an Ethereum wallet and settling in SOL for a Solana user. Polygon describes the routing as a single transaction, with customers not required to manage a bridge themselves.

The arrangement does not merge the two blockchains: businesses can keep Solana as their settlement network while using Polygon’s services for bank access, accounts, routing and payouts. In its report on the integration, CoinDesk said Solana Foundation payments general manager Jamal Raees described the deal as a way for companies to use Polygon’s regulated payment services without leaving Solana.

Who is using it, and what activity is behind the move?

Cross-border payments company Kira is among the first users, CoinDesk reported. The company uses Solana for stablecoin transfers and Polygon’s banking connections to help customers pay overseas suppliers in dollars. CoinDesk also reported Raees’s figure of more than $5.7 trillion in Solana stablecoin transfers so far in 2026. Polygon has recorded more than $3 trillion in total transfers since launch, the report said, noting that this figure includes wallet transfers and does not measure only payments for goods and services.

Polygon said the stack is intended for fintechs, payment apps, marketplaces and platforms building on Solana. Businesses can use the full flow or select components alongside their own wallet, compliance provider, ledger or settlement rail. The company said it plans to extend support to more blockchains.
