Staking yield vs. transaction fees

Hi all,

I’m trying to understand what is supporting the payment of staking rewards. From my reading, I can see staking rewards are essentially derived from three main sources: gas fees, stability fees and swap fees (Fees on Terra | Terra Docs).

Roughly ~320m LUNA is staked currently and assuming 10% p.a. staking rewards this suggests that ~32m LUNA needs to be rewarded. At a price of $60, this would imply $1.92bn (32 * 60) to be “paid”. So the question is how much fees does Terra generate a year (I assume it is definitely higher than this $1.92bn figure)

Anyone know where you can easily and quickly find Terra total transaction volumes or exact transaction fees?

Big fan of Terra!
