Polygon Extends Its Open Money Stack to Solana for Stablecoin Payments
Solana businesses can now run bank pay-ins, wallets, cross-chain routing of USDC, USDT, PYUSD and SOL, and payouts through Polygon's stack, Polygon says; cross-border payments firm Kira is among the first users.

Polygon Labs has extended its Open Money Stack (OMS) to Solana, letting businesses that operate on Solana run a full stablecoin payment through one product: bank pay-in, stablecoin balance and bank payout. Polygon announced the expansion on 29 October 2026 and describes the Solana features as live now.
The stack routes USDC, USDT, PYUSD, SOL and wrapped SOL between Solana, TRON and EVM chains in a single transaction, according to Polygon. Cross-border payments company Kira is among the first users, CoinDesk and The Block reported.
What is live on Solana
Polygon lists the following as live for Solana businesses:
Function — What Polygon says it provides
Pay-ins — Deposits by bank transfer, card, cash or crypto; virtual accounts per customer
Ramps — Fiat-to-crypto conversion on Solana and back, backed by money transmitter licences across 48 US states
Accounts — Custodial or embedded wallets on Solana, via the same API used for EVM wallets
Routing — USDC, USDT, PYUSD, SOL and wrapped SOL across Solana, TRON and EVM chains
Payouts — To bank accounts, cards, cash or wallets
Businesses can use the whole flow or individual pieces alongside their own wallet, compliance provider, ledger or settlement rail, Polygon says. It has not disclosed pricing, transaction volumes or the number of Solana customers.
A chain-agnostic bet on the payments layer
The move separates two things that blockchain networks usually bundle: the chain where tokens settle and the regulated plumbing around it. Polygon is selling the bank access, licences, accounts and routing; Solana stays the settlement layer for businesses that already chose it.
That is an unusual position for a network that competes with Solana for the same payments and stablecoin activity. CoinDesk reported that the arrangement does not merge the two blockchains. Jamal Raees, general manager of payments at the Solana Foundation, told CoinDesk the partnership gives companies access to Polygon's regulated payment services without leaving Solana.
Polygon justifies the expansion with scale: it says Solana moves more than $2 trillion in stablecoin volume each quarter. That is Polygon's figure, and it measures transfer volume, not payments for goods and services. Raees told CoinDesk that Solana has recorded more than $5.7 trillion in stablecoin transfers so far this year.
Kira as an early user
Kira uses Solana to move stablecoins and Polygon's banking connections to turn those transfers into dollars when clients pay overseas suppliers. "We already use Solana to move stablecoins, and working with Polygon helps us turn those transfers into dollars in our clients' bank accounts when they need to pay suppliers," Kira CEO Edrizio De La Cruz said in the statement reported by The Block.
Polygon says Solana is "the next chain to get Polygon OMS support, not the last" and that it will keep adding blockchains. It has not named which ones or when.
