Polygon Extends Open Money Stack Payments to Solana Businesses

Polygon Labs said Thursday, Oct. 29, that its live Open Money Stack now supports Solana, adding bank, card, cash and crypto deposits alongside wallet and payout options for businesses.

The integration lets businesses accept deposits by bank transfer, card, cash or cryptocurrency; convert fiat to crypto on Solana and back; and create custodial or embedded Solana wallets. It can route USD Coin (USDC), Tether (USDT), PayPal USD (PYUSD), Solana (SOL) and wrapped SOL across Solana, TRON and Ethereum Virtual Machine (EVM) networks. Payouts can go to bank accounts, cards, cash or wallets, spanning the flow from deposit and conversion to delivery.

Polygon’s Trails product had already linked Solana with more than 20 EVM chains, allowing transfers of SOL and stablecoins across them. The Oct. 29 integration adds deposit and payout functions around that existing routing. An earlier expansion added TRON support for USDT payment flows.

Open Money Stack joins fiat deposits and payouts with wallet services, stablecoin movement and onchain settlement through a single application programming interface (API). Its June 2026 technical preview focused on USDC and USDT activity on Polygon, along with connections to U.S. bank and cash payment methods. Businesses can also keep using their existing wallet, compliance and ledger providers instead of moving every function into the platform. Polygon has framed the product for fintech companies, remittance providers, exchanges and gig-economy platforms.

The Solana rollout follows Polygon’s completion of its Coinme acquisition on Oct. 14, part of its U.S. payments expansion. Its U.S. payments operation can serve 48 states through 37 state money transmitter licenses and 11 applicable exemptions. It is registered with the Financial Crimes Enforcement Network (FinCEN) as a money services business.

Solana had processed more than $5 trillion in stablecoin volume during 2026 as of Sept. 30. Polygon has not provided a Solana-specific customer total or transaction volume, and gave no pricing or payout-provider details.
