# Auctions

Part of the yield from the LST collateral goes to the vaults, and a part goes to the RoeUSD savings pool. This yield is deposited in the pool and a dutch auction starts.

The dutch auction bonus goes up 1% every 30 minutes, up to 50%.

In the above example, there is some collateral available for purchase. The discount bonus is now 50%, which means anyone can buy 0.034 STONE for half its oracle price.

The auction starts when yield is perceived. Monroe works with LSTs that receive yield once per day.
