Lauda,

Claimable Rewards of ANC tokens come about from:

1. Borrowing UST against bLuna and/or bETH,
2. Staking ANC, or
3. Poviding liquidity to the ANC-UST pool

When you deposit UST to the EARN function your UST gets swapped for aUST. This asset (aUST) is programed to grow at 18 - 20% per year. There are no rewards to claim. Even better… EARN doesnt actually generate interest. (Think “taxes”.) Oh the beauty of programmable money!

Enjoy!
