Yield on your market

Your market's money can earn yield while the market is open. It's on by default for any market that runs 30 days or more, and you can change it before you mint.

What the Mint page picks for you

• Yield is on, in the vault that earned the most over the past 7 days. The Mint page shows each approved vault with its APY over that week, after the vault's own fees.
• The rate is variable. It's what the vault earned last week, not a promise for the weeks ahead. A vault added in the last week shows no rate yet.
• You can pick another approved vault, or No vault. The approved vaults are listed on Yield on positions.
• Only for markets that run 30 days or more. If your market closes sooner, it has no yield option.

Your choice is locked when you mint, like the rest of the terms.

Where the yield goes

• 85% goes to the people holding positions, by the size of each stake and how long it was in the vault, whichever outcome wins.
• 15% is a handling fee. It stays in the market.
• The yield earned on your seed stays in the market too.

The handling fee and the yield on your seed are split between your creator pool and the treasury, the same way as the spread and losing stakes. The split for markets minted today is on Current promotions.

Yield is paid at resolution. It earns no Mint Points, for you or for anyone holding a position.

When the money moves

• While your market is open, its money goes into the vault. Nothing new goes in during the last 30 minutes before close.
• Each vault has a cap on how much ULTRAMINT puts into it across all markets. When a vault is full, new money stays in your market until there's room.
• ULTRAMINT can stop new money going into the vaults at any time, for every market or for one. It never stops money coming back out.
• After close, the money comes back out of the vault before your market can settle.

What it can cost you

• Your seed takes a vault loss early. If the vault loses value, the loss hits what the market kept first, then your seed, and only then what holders are paid.
• Settlement can wait. A vault can pause or run short of cash. Your market can't settle, and you can't be paid, until the money is back.
• Someone else runs the vault. Each vault's manager, or Aave's governance, sets its fees and decides where it lends. They can change that while your market is open.
