If your USDC Simplecard looks grey in the app, the card is closed and can no longer be used for payments.
Why a card is closed
Inactivity. A card that is not used for more than a month is closed automatically.
You closed it yourself in the app.
What to do
Do not top up the closed card.
Open the Cards section and issue a new card. Your account and verification stay the same, so you don't need to verify again.
Top up the new card and use it as before.
Good to know
You can have only one active card at a time. A new card can be issued only when the current one is closed.
Each account can issue a limited number of cards (closed cards count). When the limit is reached, a new card can't be issued, but your Self-Custody wallet keeps working as usual.
Your wallet balance is not affected when a card is closed.
Need help? If the app doesn't let you issue a new card, send us a screenshot of the Cards screen in the chat.
