Freezing your card blocks every transaction immediately — useful if you misplace your phone or notice anything unusual. There is no fee, and you can unfreeze whenever you are ready.
- 1Open the Card page.
- 2Tap Freeze card. Spending is blocked instantly.
- 3When ready, tap Unfreeze to resume normal use.
ℹ️
Freezing does not affect your collateral — your USDC stays untouched in your self-custody wallet while the card is frozen.
