Cards

Gravv lets you instantly issue virtual payment cards, each powered by stablecoin balances. Gravv-issued cards are linked directly to a single account.

Card workflow

To issue and manage cards with Gravv:

1. Create a Card Account on your Dashboard. If you are creating a Card Account in the Sandbox environment, then select Ethereum as the blockchain network backing the account. However, if you are creating a Card Account in the Production environment, select Polygon.

This is a one-time setup, and it's meant to back all the cards you will be creating for your customers. The account must be backed by the Polygon blockchain network and the bank must be Lead Bank.

2. Save the account ID in your environment variables.

Include this account ID in all the card application request you will be sending through the Create card application endpoint.

3. Create a customer to obtain a customer id.
4. Complete Intermediate KYC verification. This is mandatory for card creation.
5. Ensure the customer's KYC level is intermediate.
6. Submit a card application using the Card Account ID you saved in step 2.
7. Create the card once the application is approved.
8. Retrieve the card details to share with your customer.
9. Fund the card by using the Transfer endpoint. For more information on funding issued, see Fund cards cards.
10. Withdraw funds from the card when needed.

Using cards
