Stablecoin Checkout. Drop-in, hosted, yours.
Embed a hosted stablecoin checkout in your existing flow. White-label the surface, enforce the chain and coin you settle in, and let funds land directly in your wallet.
Every route to a crypto checkout forces a bad trade today. Building your own is a multi-month project: wallet connection UX, chain selection, social login, exchange-rate locking, and a long tail of edge cases that have nothing to do with your product. Custodial checkout products (CoinsPaid, BitPay) hand you the integration but take the funds: customer payments pool in the processor's wallets, you wait on their settlement schedule, and their security becomes your risk, the exact architecture behind roughly $1.8 billion in processor hacks between 2023 and 2025. The brand-name option narrowed sharply when Coinbase Commerce shut its merchant portal in March 2026: its successor checkout runs on Base only, supports USDC only, and bans iGaming outright, as do most card-first processors. High-risk merchants are left choosing between an engineering project they should not need, a custodian they should not trust, and a product that excludes their vertical by policy. What you actually want is boring: a checkout that looks like yours, behaves like yours, settles in the asset and chain you choose, and never holds your money.
PYMSTR Checkout is a drop-in hosted crypto checkout you ship via redirect URL the same day, or embed as an iframe inside your existing flow. Theme it with your colours, logo, and copy, so the customer never leaves your aesthetic. You decide the rails: restrict the checkout to the exact stablecoins (USDC, USDT) and chains you settle in, and the customer cannot pick anything else, which removes wrong-chain support tickets by construction. Customers without a wallet sign in with Google, email, SMS, or Apple and get an embedded wallet automatically; customers with MetaMask, WalletConnect, or Coinbase Wallet connect directly. Settlement is non-custodial and on-chain: funds move from the customer's wallet to yours in seconds, with no processor balance, no payout schedule, and no reserve held against you. The moment a payment confirms, an HMAC-signed webhook fires so your order system reconciles automatically. iGaming and high-risk verticals are supported by design, not by exception, and pricing is 1% flat with no setup fee, no monthly fee, and no KYB to start.
