Gas credits are paid with USDC.

You'll see a "[↩] Refunded" indicator in your transaction history. + +### Can I get a refund of unused credits? + +Gas credits are non-refundable, but they never expire. You can use them anytime for future transactions. + +### How long do credits last? + +Gas credits never expire. Use them whenever you need to make transactions. + +### What's the minimum top-up? + +The minimum top-up is 0.5 USDC. The maximum is 100 USDC per transaction. + +### Can I use gas credits for all transactions? + +Most transactions are supported, but some operations (like closing accounts) cannot be sponsored. In those cases, you'll need to use SOL for gas fees. + +### How do I disable gasless mode? + +Open the Gas Credits screen and toggle **Gasless Mode** to disabled. Your preference is saved automatically. + +### Where can I see my transaction history? + +Open the Gas Credits screen and scroll down to see your top-up and usage history.
