Polygon Labs has extended its stablecoin payments infrastructure to Solana, bringing its Open Money Stack to the rival network for the first time. The expansion gives businesses building on Solana a single connection for pulling money in from bank accounts, moving crypto across chains, and paying out to customers and suppliers around the world.

The Open Money Stack is a bundle of payments tools designed to address a persistent headache in crypto payments: sending tokens on-chain is often the easy part, but getting money from a bank account into a wallet, converting it, and landing it back in a recipient's bank account typically requires stitching together several providers, each with its own integration and contract.

Polygon's platform collapses that complexity into one technical connection and one commercial relationship. Businesses are free to adopt the full suite or mix individual components into their existing systems.

Through the stack, a Solana-based business can connect bank, card, cash, and crypto funding routes; spin up embedded wallets; route and convert funds across networks including Polygon, Ethereum, and Tron; and deliver payouts into banks, cards, or wallets. A remittance provider, for instance, could take dollars from a sender, deliver USDC on Solana, and connect the recipient to a bank payout.

"Every bank and fintech that wants to use crypto faces the same problem: connecting them to the accounts and payment systems its customers already use," said Sandeep Nailwal, co-founder and CEO of the Polygon Foundation. He added that adding Solana lets more businesses build on the network their customers choose.

Cross-border payments firm Kira is among the first to adopt the stack on Solana, using it to help clients turn stablecoin transfers into dollars in their bank accounts to pay overseas suppliers. As one of the first movers, Kira offers an early live view of how the stack handles the bank-account leg of stablecoin payments on Solana.

The move reflects Solana's growing pull as a payments venue. According to the Solana Foundation, the network has processed more than $5 trillion in stablecoin volume this year. Solana recently rolled out an institutional settlement standard developed with input from J.P. Morgan and went live with its Alpenglow upgrade. For payment businesses, Solana now combines that on-chain volume with institutional-grade settlement tooling and, as of this expansion, off-the-shelf payment rails.

For Polygon, the expansion builds on a broader payments push, including its acquisition of crypto-cash firm Coinme.
