Polygon expanded its Open Money Stack with merchant checkout for crypto payments, a fiat-balance feature that can be converted to stablecoins, and a security review for the stack’s core API and dashboard. The product set is aimed at business payments and checkout flows, with multiple options for wallets, tokens, and blockchain networks. One item also says the stack is being used as a route for moving funds through compliance, accounts, wallets, conversion, routing, settlement, and connected rails.

Key claims & sources

✓
On 17 August 2026, Polygon OMS added the ability for businesses to hold a USD balance inside the stack and convert it to stablecoin when they are ready to move money.
✓
On 2 September 2026, Polygon Labs said it completed a SOC 2 Type 1 examination for the Open Money Stack API and dashboard, with Schellman & Company performing the review and SOC 2 Type 2 still underway.
✓
Polygon introduced Crypto Checkout on 1 October 2026 as a merchant payments product for stablecoin and other digital-dollar checkout, and businesses can choose the assets they receive.

What it means

Businesses using the Open Money Stack notice the change first, because the checkout product is built for merchants and the fiat-balance feature is framed for treasury, payout runs, and cross-border payments. The security exam also matters to teams that handle the API and dashboard, since that review covers the controls around those parts of the stack.

In practice, the stack now covers more of the payment flow than a single chain or wallet would on its own: it includes checkout, holding a USD balance, and later converting that balance to stablecoin. What stays the same is that the stack still depends on separate pieces for compliance, accounts, wallets, conversion, routing, settlement, and the rails between them.
