Polygon Labs announced on October 29, 2026, that its Open Money Stack now supports Solana. The update lets businesses run complete stablecoin payment cycles from bank deposits to balances to payouts via one API without switching settlement chains.
Core features now live on Solana
Businesses can accept deposits through bank transfer, card, cash, or crypto. The stack converts fiat to stablecoins on Solana and back, with options for custodial or embedded wallets. Programmable rules control money movement across accounts.
Cross-chain routing moves assets between Solana, Polygon, Ethereum and other EVM chains, and TRON. Payouts reach bank accounts, cards, cash locations, or wallets. Supported assets include USDC, USDT, PYUSD, SOL, and wrapped SOL.
Regulated U.S. on- and off-ramps come from Coinme, acquired by Polygon on October 14, 2026. The service covers 48 states through 37 money transmitter licenses plus FinCEN registration. Solana-EVM routing has operated since August 2026, with TRON added in October 2026.
Background and volume context
The move follows Solana’s Alpenglow upgrade, which cut finality to roughly 150 milliseconds. Token Terminal data shows Solana processed about $5.76 trillion in stablecoin transfers from January 1 to October 27, 2026. Polygon’s cumulative volume exceeds $3 trillion. The Open Money Stack aims to remove the need for separate payment rails by unifying bank connections and blockchain settlement.
Kira, a cross-border payments firm, became one of the first users. It converts incoming Solana stablecoin transfers into USD for client bank accounts and supplier payouts. The integration removes manual steps that previously required separate wallets and banking partners.
Practical benefits include reduced operational overhead and faster settlement. Companies that previously maintained multiple provider relationships can now route deposits, conversions, and payouts through a single set of credentials and compliance controls.
Next steps and expansion plans
Polygon stated it will continue adding blockchains to the Open Money Stack. No additional chains or timelines have been confirmed. Developers can test the Solana endpoints through existing Polygon documentation and the Trails routing layer.
Teams evaluating payment infrastructure should review the API reference for bank integration and cross-chain payout endpoints. Early testing with Kira shows measurable reduction in settlement time for international supplier payments compared with legacy correspondent banking routes.
Frequently asked questions
What assets does the Polygon Open Money Stack support on Solana?
The integration supports USDC, USDT, PYUSD, SOL, and wrapped SOL. Users can hold balances, convert between fiat and these tokens, and route them across chains through the same API.
How does Kira use the new Solana support?
Kira converts incoming Solana stablecoin transfers into USD and sends funds directly to client bank accounts or supplier payment rails. The setup replaces separate wallet and banking connections with a single integration.
What regulatory coverage backs the U.S. fiat rails?
Coinme provides the on- and off-ramps after its October 2026 acquisition by Polygon. Coverage spans 48 states through 37 money transmitter licenses, 11 exemptions, and FinCEN MSB registration.
When did cross-chain routing between Solana and EVM chains become available?
Solana-EVM routing launched in August 2026. TRON support was added earlier in October 2026, allowing asset movement across four major networks through the Trails infrastructure.
