A crypto invoice is a bill that requests payment in cryptocurrency for goods or services rendered. Technically, it's a unique address on the blockchain that a business creates to receive payment from a customer. It typically includes details such as the transaction amount in the specified cryptocurrency, the recipient's wallet address, a description of the products or services, and any applicable terms or conditions.
Calypso Pay invoices are used for accepting crypto payments, allowing merchants to receive Bitcoin, Ethereum, Tron, TON, and other cryptocurrencies securely from customers in exchange for goods or services. This streamlines the process of accepting various digital currencies for businesses.
The best option is to integrate with our payment gateway API. When your customers proceed to pay, our system automatically generates an invoice.
To create an invoice with Calypso Pay, merchants can either generate an invoice via API for seamless integration or manually create it in the application interface.
Transaction speed depends on the blockchain network's load. On average, BTC transactions take from 15 minutes to 4-6 hours, Ethereum up to 15 minutes, Tron, BSC, Polygon, and Doge around 5 minutes, and TON up to 1 minute.
