Built for

customers.

A meaningful slice of every iGaming operator's global player base already holds USDC or USDT. Cards can't reach those players in most of their regions. PYMSTR is the rail that can.

We weren't looking to replace our card processor. We were losing deposits from players who only hold stablecoin. PYMSTR filled that gap in under a week.

No. PYMSTR is stablecoin-in, stablecoin-out. Customers pay in USDC or USDT; you receive the same stablecoin in your wallet. When you want fiat, you off-ramp through any exchange or OTC desk you choose. We do one thing well, the checkout, and stay out of custody and conversion.
No. PYMSTR is an additional rail. Keep your card processor for card payments. Add PYMSTR to accept stablecoin from customers who already hold it.
They need a stablecoin balance. They don't need to install anything. PYMSTR creates an embedded MPC wallet when they log in with Google, email, SMS, or Apple. Customers who don't already hold stablecoin aren't the target for this rail.
Because PYMSTR is non-custodial, funds never touch our servers. They go straight from the customer's wallet to yours. That reduces our regulatory surface and yours. Your own KYC/AML obligations as a merchant still apply.
1% flat on stablecoin transactions. No tiers, no reserves held against you, no minimum volumes. Network gas is paid in the stablecoin at checkout. No separate gas bill.
Stablecoin transactions settle on-chain and are final. There are no chargebacks to manage and no dispute fees, but that also means PYMSTR is not a buyer-protection layer. Use it for payments that should be final, the way a bank transfer is final. Card disputes stay with your card processor.
USDC and USDT across Ethereum, Base, Polygon, Arbitrum, and BNB. You choose which ones to accept. Customers pay exactly what you specify.
Same-day with payment links. Two days for a full API integration.
PYMSTR never holds your money. Customer payments settle directly to your wallet on-chain. There's nothing for us to lose on your behalf.
