What did Polygon add to its payments platform?

Polygon Labs added Solana to its Open Money Stack, per The Block on October 29, 2026. Businesses can fund from bank accounts, move value across chains and pay recipients through one integration.

Which networks does the stack now support?

Solana, Polygon, Ethereum and TRON. TRON was added earlier in October, according to The Block.

Who is using the Solana integration?

Kira is named as one of the first customers. It moves clients between dollars and stablecoins and pays overseas suppliers. Its CEO said it already uses Solana to move stablecoins.

Has Polygon disclosed economics for the Solana route?

No. The Block's report gave no pricing, take-rate or volume for the Solana route.

Polygon adds Solana to its Open Money payments stack

Polygon Labs now routes bank funding, cross-chain transfers and payouts over Solana. The licences behind it matter more than the new chain.

Polygon's addition of Solana to its Open Money Stack is a distribution move, not a technology breakthrough: it lets businesses reach Solana's stablecoin rails through one integration alongside Ethereum, TRON and Polygon. The Block reported the change on October 29, 2026; Kira is an early customer, and Polygon's Coinme acquisition supplies U.S. licences.

Polygon Labs added Solana to its Open Money Stack, which already covered Polygon, Ethereum and TRON, per The Block (Oct. 29, 2026).
One integration now covers bank funding, cross-chain movement and payouts to bank accounts, cards, cash services and crypto wallets.
Polygon's completed Coinme acquisition reportedly brings money transmission licences or exemptions covering 48 U.S. states.
No pricing, take-rate or Solana-route volume was disclosed, so the commercial impact is unproven.
Kira, a cross-border payments customer, is named as an early user; broader adoption is the figure to watch.

Polygon Labs has added Solana to its Open Money Stack, giving businesses one integration for bank funding, cross-chain transfers and payouts. The move, reported by The Block on October 29, 2026, widens routing options rather than changing the economics. The test is whether money clears at lower cost, and no pricing or volume for the Solana route has been disclosed.

What Polygon actually shipped

Polygon Labs added Solana to its Open Money Stack, so a business can use one integration to take in bank-account funding, move value across chains and pay out to recipients. The Block reported that the stack already supported Polygon, Ethereum and TRON, with TRON added earlier in October. Customers can offer accounts and wallets, convert funds, and route payments to bank accounts, cards, cash services and crypto wallets. The report did not disclose pricing or volumes for the Solana route.

Why the timing favors Solana

The addition came about a week after Solana activated its Alpenglow upgrade, which The Block reports cut transaction finality from roughly 12.8 seconds to 150 milliseconds. Faster finality shortens the on-chain leg of a payout, but it does not shorten the fiat leg. Bank-rail settlement still sets the end-to-end lag, so the practical gain depends on how much of each flow stays on-chain.

The licences and capital behind the stack

Polygon's completed Coinme acquisition is the structural piece, bringing money transmission licences and exemptions covering 48 U.S. states, per The Block. Cointelegraph reported a deal valued at about $250 million covering Coinme and Sequence. Separately, The Block reported in April that Polygon Labs was seeking up to $100 million for its payments business; that was a report, and this analysis found no confirmation that a raise closed.

What to watch next

The missing numbers decide whether this matters: authorization rates, take-rate per payout and Solana-route volume. The Block cites Solana Foundation's Vibhu Norby saying Solana processed more than $5.5 trillion in stablecoin volume in 2026, a network-level figure that says nothing about Polygon's flows. Kira is the only named customer, so disclosed volume from it or others would be the first real evidence.

For treasury and payments teams evaluating stablecoin rails, the takeaway is concrete: ask any stack provider for settlement times on the fiat leg, per-payout fees and licence coverage by jurisdiction before treating a new chain as a cost saving.
