Hold Dollars in Polygon's Open Money Stack. Convert to Stablecoins the Moment You're Ready.

tl;dr:

• Keep a USD balance in Polygon OMS, then convert to stablecoin when you need to move money.
• No new wire required, no waiting on banking hours, cutoffs, or the next business day.
• That comes in handy for treasury, cross-border payments, payout runs, and those inconvenient moments when the banks are closed

Polygon OMS now lets businesses hold a fiat balance inside the stack, so converting your USD to stablecoins never has to wait on a new wire. If you’re already moving money through OMS, dollars can sit staged and ready, and convert to stablecoins the moment you need to move money.

The slow part? Usually the bank transfer

Stablecoins can move quickly. Getting the dollars into position is often what takes time. Historically, that meant wiring money from an external account into Polygon OMS before each conversion. And bank transfers keep bank hours: Fedwire runs on weekdays only, ACH takes a day, or same-day if you catch the cutoff. None of it runs on a Saturday.

A fiat balance gives those dollars somewhere to wait. Fund it ahead of time, then convert to stablecoin when you’re ready. That’s one less wire to initiate and, potentially, one less banking day standing between you and the payment.

Picture this:

It’s Friday evening, and a payment run needs to go out. Send a wire now and, depending on the timing, it may sit until Monday. Fedwire’s active window closes at 5:30 PM ET on weekdays, and next-day ACH settles at 8:30 AM ET regardless of when you submitted it. That can leave more than 60 hours before the money even starts moving.

But if the dollars were already sitting in a Polygon OMS fiat balance, you could convert them to stablecoins and settle the payment before the bank opened Monday morning.

How it works

Think of a fiat balance as a place to park US dollars inside Polygon OMS, separate from your stablecoin wallet, until you need them. You fund it the same way you already fund OMS: wire transfer, ACH, or SWIFT, the same fiat rails OMS uses today. Once the dollars land, they stay ready. When it’s time to move money, you can convert them to stablecoin in seconds instead of waiting for another wire to arrive and clear.

Your fiat balance is held by one of our licensed banking partners, the same way it already handles every fiat payment moving through OMS. Polygon Labs builds the technology that connects your balance to stablecoin conversion and onward settlement.

And sometimes you may not need stablecoins at all. That’s fine too. A non-US business with a virtual account in OMS can pay a US vendor straight from its fiat balance, dollars in and dollars out, with no stablecoin conversion anywhere in the flow.

Use cases

Cross-border entity routing

Say a Canadian entity needs to pay a Singapore entity. The payment can settle through one US-based fiat balance instead of requiring a new correspondent banking relationship in every corridor.

Payout batching

Got a payout batch due Monday morning? Payment platforms and marketplaces can stage the dollars ahead of time, so the stablecoin conversion isn’t waiting on a wire that clears Monday afternoon.

Treasury staging

You don’t have to move an entire treasury balance onchain to make this useful. Keep a working slice inside OMS, convert what a payment run needs, and leave the rest where it is.

How this differs from what’s out there today

Standard on-ramp flows from Bridge, Crossmint, MoonPay, and other stablecoin orchestrators work much the same way: once incoming fiat clears, it is automatically converted to stablecoins. That doesn’t remove the wait, it just moves it. The dollars still have to land first, over the same wire or ACH rail, before any conversion can trigger. A fiat balance in OMS changes the order of operations: the dollars can already be there, ready to convert when you need them.

Part of the same stack, not a new one

And you don’t need to add another product or integration. Fiat balances sit inside the OMS Dashboard and use the same fiat rails customers already rely on to move money in and out of OMS. If you’re already sending and receiving through OMS, this simply gives your dollars somewhere to sit in between.

When you’re ready to move money, the dollars are ready, too. Talk to the OMS team about setting up a fiat balance for your business.
