For customers / I want to pay
Review the details.
Then pay in USDC.
Use a QR or payment link provided by the merchant you intend to pay.
Open the QR or payment link.
Check the business name, amount, receiving details, and network. If anything is unfamiliar, confirm it with the merchant before connecting your wallet.
Have USDC on the selected network.
Your wallet must support this payment flow and hold USDC on that same network. A balance on another network or in a custodial exchange account may not work.
What if I don’t have USDC?
You can receive USDC from someone else or obtain it through a service available to you. Confirm that it can transfer USDC on the network requested by the merchant, and review its fees, limits, and requirements. PayIn does not sell USDC or recommend a purchase provider.
Review the wallet request and fees.
Check the amount, network, and recipient before signing. Network or service fees may apply; how they are paid depends on the flow. Never enter a private key or recovery phrase into PayIn.

Wait for confirmation.
A wallet signature alone is not a payment receipt. Check the payment result. If it is delayed or unclear, ask the merchant to check before attempting to pay again.
