Fees shown before payment
Review the amount and any applicable fees for each payment request before sharing it. Your customer sees the total before paying.
Gateway fee
The amount is calculated from the fee rule configured for the merchant and invoice. ZemiaxPay does not publish a universal percentage that may not apply to your account.
Exact payer total
Hosted crypto invoices default to a net target: the checkout shows the exact amount to send, the gateway fee and the merchant amount before payment.
Network fee
The sending wallet pays the blockchain network fee. ZemiaxPay keeps that cost separate and never guesses it inside the merchant amount.
Connect your website
Authenticate with a scoped key, use an idempotency key for writes and verify every webhook before fulfilment.

Invoice, payment, confirmation and ledger records remain separate and traceable.
Payment questions
Availability depends on the receiving route, pricing source, watcher and confirmation policy configured for each merchant.
Does the buyer need a ZemiaxPay account?
No. A buyer can open the hosted checkout and pay the route assigned to the invoice.
Which cryptocurrencies can a merchant accept?
The catalog covers multiple assets and networks. A route appears at checkout only after that merchant has a ready receiving route, pricing source and watcher or provider.
Where do received funds go?
The destination depends on the configured receiving route. ZemiaxPay can monitor an external receiving address while recording the payment and ledger facts.
Where are received funds held?
ZemiaxPay monitors external receiving addresses and records payment facts. It never stores signing keys or sends funds from the VPS.
