OUSD rewards: Open USD went live paying the platforms that circulate it, not the people who hold it — what that means for merchants

What went live on September 30

Open USD was announced on June 30, and we covered what the launch meant for merchants at the time. Today the token is real. According to CoinDesk and other launch coverage, here is what went live:

• Chains: Ethereum, Solana, Base and Tempo, the Stripe-backed payments chain.
• Issuer and reserves: Bridge, a Stripe company, issues the token. Reserves are held at BlackRock, BNY and Lead Bank, with monthly attestations promised.
• Access: businesses can mint and redeem 1:1 against the dollar, with no fee at any size, through Mastercard (via BVNK), Stripe and the Visa Stablecoin Platform. Coinbase access starts October 1. OUSD also trades on Coinbase, Kraken and Uniswap.
• Liquidity: the five founding partners, Coinbase, Mastercard, Shopify, Stripe and Visa, each hold an equal initial equity stake and committed more than $1 billion in launch liquidity.
• Network: more than 200 partner companies, up from 140 in June. Recent additions include UBS, SBI Holdings and Jeeves.

CEO Zach Abrams summed up the pitch in one line: "Every other stablecoin is building a fund. We're building money." To see what he means, look at where the reserve income goes.

How OUSD rewards work: the float follows whoever moves the money

Every fully reserved stablecoin makes money the same way. Holders hand the issuer dollars, and the issuer invests them in short-term Treasuries and cash. The interest on that pile is the business. The real question is who gets it.

Tether keeps it. Circle shares a large part of USDC's income with Coinbase as its distribution partner, a deal detailed in Circle's 2025 IPO filing. OUSD makes that kind of deal the whole design and opens it to everyone. Open Standard says it will share nearly all reserve revenue with the partners that grow adoption. Each partner earns in proportion to the OUSD supply and activity it drives. Partners above an undisclosed threshold also earn equity, and Abrams says "the overwhelming majority of our cap table" will go out that way over four to five years. Founding partners get no special share. They earn under the same formula as everyone else.

Then there's the law. Section 4(a)(11) of the GENIUS Act says an issuer may not pay "the holder of any payment stablecoin any form of interest or yield (whether in cash, tokens, or other consideration) solely in connection with the holding, use, or retention" of the coin. So OUSD doesn't pay holders. It pays distributors, and distributors decide what to do with the money. Launch coverage gave one example: Ramp, a partner that runs stablecoin accounts on Stripe, will let its business customers hold OUSD balances and earn rewards.

That passthrough is the part regulators are still arguing about. The OCC's February proposal, as Sidley's analysis explains, would create a rebuttable presumption: certain arrangements in which an affiliate or related third party pays holders yield "solely in connection with" holding count as prohibited evasion. The proposal doesn't define either "yield" or "holder." The FDIC's proposal takes a similar approach. The Federal Reserve published its own GENIUS proposals on September 24. The OCC has said its final rule is coming by November. And the Senate market-structure bill that would have settled platform rewards died on September 15, so for now the regulators have the question.

The pattern that follows, and that platforms have already adopted, is to tie rewards to activity rather than to simply holding: a credit per order, cashback per purchase, a reward for moving money. Whether a given program is permitted is a question for lawyers, not for this article. But that shape explains what's about to show up at your checkout.

The precedent is already in checkout

Stablecoin incentives in checkout already exist. Shopify's help center describes how its USDC acceptance works today:

• Merchant credits on USDC orders. They start with your first USDC transaction. If you take payouts in fiat, the credit is added to your next payout. If you keep a USDC balance, it's added to that balance.
• Buyer cashback. Customers who pay with USDC on Base can get cashback in USDC, paid to their wallet 30 days after purchase and capped at 100 USDC per transaction.
• A catch on refunds. If the cashback has already gone out and your return window is longer than 30 days, Shopify automatically caps the refund you can issue.
• No disputes. Customers can't open disputes on orders paid in USDC, which says something about what the payment is.
• Two payout modes. Shopify converts the USDC to fiat on its normal payout schedule, or you keep a USDC balance and claim it to a wallet you connect for each withdrawal.

Nobody hands out cashback on a payment method unless the payment method pays for it. Card rewards come from interchange. Stablecoin rewards come from float. The company whose checkout is the model for stablecoin incentives is now a co-owner of a coin designed to pay its distributors for exactly that activity.

Why it matters: stablecoin float is becoming a marketing budget

Put OUSD's formula next to the Shopify precedent and you get a model of the next two years. Every distributor now earns more when more OUSD sits on its platform and moves through it. In payments, that pays for three things.

Steering the tender. A platform that earns on one token and not another will price them differently. Expect credits, lower rates or buyer cashback for settling in the coin the platform earns on. It's the stablecoin version of a card network paying for preferred placement.

Keeping the balance. Supply counts while it stays in circulation on the platform. A merchant who withdraws every receipt to their own wallet the same day doesn't add much. A merchant who leaves a working balance inside the platform does. Rewards tied to where you hold the balance are, by design, retention offers.

Pushing into checkout. At a Sibos-week panel in Miami on September 29, panelists ordered stablecoin adoption this way: B2B payments first, then treasury, with checkout last. Consumer checkout is the hardest place to change behavior, and incentives are how platforms plan to change it.

Here's a rough sense of the money. Take a business that keeps an average of $200,000 of stablecoin receipts on a platform. At a hypothetical 4% reserve yield, that balance earns about $8,000 a year. Under OUSD's model, nearly all of it goes to the distributor. The distributor decides how much comes back to the merchant as rewards, if anything, on terms it can change. The numbers here are illustrative, not a forecast. The structure is the point.

None of this is sinister. It's how rewards cards, sweep accounts and payment-for-order-flow work. But it changes a question most merchants never had to ask. With cards, the fee was the cost. With incentivized stablecoins, the cost can hide in custody, exit terms and tender lock-in, dressed up as a reward.

It also sharpens the USDT vs USDC split instead of resolving it. OUSD launched with a little over $1 billion of committed liquidity. The whole stablecoin market is over $300 billion. Your customers and suppliers will keep holding what they hold. A reward to settle in a coin they don't use is a reward to add a conversion step.

Five questions to ask before you take a stablecoin rewards offer

Whether the offer involves OUSD, USDC or the next coin with a distribution budget, these five questions tell you what you're being paid for.

1. Who holds the balance? If your receipts sit in the platform's account and not in a wallet you control, you're a creditor of that platform. The reward pays you for accepting that counterparty exposure.
2. What does the reward depend on? Per order, per balance or per month of staying? If it disappears when you withdraw, it's paying you to stay.
3. What does it cost to leave? Free 1:1 redemption is available to businesses integrated with the four access routes. For everyone else, find out the withdrawal fee, the timing and the networks, and whether you can send the token to your own wallet at all.
4. What's the underlying fee? A credit on an acceptance rate is a discount on a fee. Compare the net rate with what an on-chain payment actually costs to settle.
5. Can the people you pay use the token? If your suppliers, contractors or payroll run on USDT or USDC, a reward for settling in anything else adds a conversion. That conversion is priced by someone.

And one question for your advisers: whether a particular rewards program is permitted, and how to account for it, is still open until the GENIUS rules are final. The Act takes effect on January 18, 2027, or 120 days after the final rules are issued, whichever comes first.

What changes for different businesses

Incentivized stablecoins hit businesses differently, depending on how much sits in the balance and how often it moves.

• An online store taking stablecoins through its commerce platform. This is where incentives will show up first, as credits or buyer cashback at checkout. Check the refund rules: Shopify's cashback cap on refunds is a reminder that incentives create side effects in operations.
• A B2B exporter invoicing buyers abroad. Big tickets mean big balances, which is exactly what distributors want to keep. A $150,000 invoice paid in stablecoins and left on a platform for a month helps someone else's supply numbers. Settle to your own wallet, then decide.
• A shop, café or salon taking in-person payments. Tickets are small and there's no balance to speak of, so the float math is tiny and a reward is marginal. What matters is getting paid on the spot, with no chargebacks and no card terminal. A QR checkout on any phone covers that.
• An API or data seller charging AI agents. Agent payments are paid per call, almost entirely in USDC. Revenue arrives in thousands of tiny transfers. If it goes straight to your wallet, no balance builds up in the middle.

Where Payzum fits: acceptance with no balance in the middle

Payzum is a non-custodial, crypto-only payment processor. Funds go straight to wallets the merchant controls. Payzum never holds, pools or controls them, so there's no Payzum balance for anyone to earn float on, freeze or use as leverage to keep you. The settlement is the payment.

To be clear about what this is and isn't: Payzum doesn't pay rewards on balances, because it never holds one. Holding stablecoins in your own wallet doesn't earn you interest either. The reserve income stays with the issuer and its distributors either way. Self-custody isn't a yield strategy. It's about control: you choose the token, you choose when to move it, and nobody else's terms sit between the customer's payment and your money.

What you get instead:

• Your choice of tender. Customers can pay in the crypto they hold. With optional auto-convert, every sale settles in USDC or USDT, the two dollar tokens that dominate payments.
• No acquirer, no card-network fees. An on-chain payment costs a network fee. There's no percentage rate that needs a rebate to look competitive.
• Finality. On-chain payments can't be reversed, so there are no chargebacks.
• Speed. Funds are spendable on confirmation: about 0.4 seconds on Solana and about 2 seconds on Base and Polygon, any day of the week.
• Money out from the same wallet. Pay suppliers and contractors with stablecoin payouts on Polygon, Arbitrum, Optimism, Base, BNB Chain and Avalanche, or run mass payouts by CSV.

How it works, step by step

1. Connect wallets you control. You provide the destination addresses. No platform account holds your receipts.
2. Choose how you get paid. Online: hosted checkout, no-code payment links and buttons, invoices with expiry and overpayment detection, subscriptions, or a drop-in plugin for WooCommerce, Magento, PrestaShop, Shopify and other carts. In person: the POS, with a new QR code for every sale and PIN-protected cashiers. For APIs: x402, where Payzum sits in front of your existing endpoint as middleware and settles through an external facilitator.
3. Pick networks and a settlement currency. Choose from Bitcoin, Ethereum, Solana, Polygon, Base, Arbitrum, Optimism, BNB Chain and Avalanche. Turn on auto-convert to USDC or USDT if every sale should settle as a dollar.
4. Reconcile automatically. Signed webhooks fire on every payment, the REST API exposes the same events, and a full audit log records what settled and when.

Incentivized platform balances vs your own wallet: comparison

What a stablecoin rewards model changes, compared with non-custodial settlement.

Fair objections

"A reward is free money. Why wouldn't I take it?"

Maybe you should. If the platform is solid, the net rate beats your alternatives and you'd keep the balance there anyway, the reward is real value. Just price it as what it is: payment for tender choice and custody, with terms the platform can change. Take it with your eyes open, not by default.

"Isn't holding my own wallet riskier than a platform account?"

It's a different risk. Self-custody means you manage keys and operating procedures. A platform account means you depend on the platform's solvency, compliance decisions and withdrawal terms. We've watched providers shut down overnight. Many businesses split the difference: they settle to their own wallet and move amounts to exchanges or banks as needed.

"Should we start accepting OUSD?"

Start from what your customers and suppliers actually hold. On day one, OUSD had a little over $1 billion of committed launch liquidity, in a market of more than $300 billion dominated by USDT and USDC. If demand for it shows up in your checkout, that's the signal. A distributor's incentive isn't.
