Paying at Checkout
Users can pay in two ways at checkout.Sign & Pay
The user connects their wallet, reviews the payment amount, and signs the transaction directly on-chain. This includes MetaMask, Phantom, Rabby, Coinbase Wallet, Binance Wallet, and any other non-custodial wallet.
Deposit
A QR code and deposit address are displayed at checkout. The user sends funds from any wallet or centralized exchange, no wallet connection required.
The deposit address shown at checkout is not your wallet. Suby creates a dedicated smart account per customer to receive and track funds accurately.
Settlement
Both payment methods route through the same smart contract logic.There is no holding period, no aggregation across transactions, and no manual action required on your end.
Pricing & Conversion
All product prices are defined in USD. At checkout, Suby calculates the equivalent token amount in real time.Pyth Price Feeds
Token conversion rates are powered by Pyth, providing accurate, real-time pricing across all supported assets. The rate is locked at the moment the user initiates payment.
