# Terms and Definitions

**Merchant** – a goodPayments user who uses the service to accept cryptocurrency payments for goods or services.

**Payer** – the merchant’s customer who completes the payment using the invoice created by the merchant.

**Invoice** – a payment request generated by the merchant via the API or the goodPayments dashboard. Each invoice includes the payment amount, currency, expiration time, and the cryptocurrency address for payment.

**Temporary Address** – a unique, single-use blockchain address generated when an invoice is created. It remains active only for the duration of the invoice’s payment window. Once the payment is completed or the invoice expires, this address becomes inactive and is no longer monitored.

**Static Address** – a permanent cryptocurrency address generated when an invoice is created with the «Static» address type. Unlike a temporary address, a static address remains active and continues to be monitored until manually deactivated by the merchant. A static address can receive multiple incoming payments.

**Forwarding Address** – the merchant’s own wallet address, specified in the account settings. goodPayments automatically forwards all funds received on paid invoices to this address. This is the final destination for incoming payments.

**Activation Address** – a service-generated address used by goodPayments to activate temporary addresses created for invoices. It ensures that temporary addresses can perform outbound transactions when needed.

**Address Activation** – the process required in the Tron blockchain to enable outgoing transactions from a newly created address.

**AML Check** – an automated screening of incoming transactions for risk. The check is designed to identify potential links between the incoming asset and illegal activity.

**Service Fee** – the goodPayments fee for processing an incoming payment and forwarding funds to the merchant’s wallet. The fee amount depends on whether the merchant’s address holds USDT.\
The fee is **6.5 TRX** if the merchant wallet contains USDT, otherwise **13 TRX**.
