MPL Staking Rewards

Public MPL Staking launches 10am ET Thursday 22 July. Staking receives one-tenth of the interest yield in a pool plus MPL rewards.

The APY from MPL rewards will vary depending on 1) the volume of MPL which is Staked; and 2) the MPL price.

Every month there will be a single deposit of a fixed number of MPL to the Staking Rewards Contract. This will be determined based on:

  • Average MPL price over preceding 7 days
  • Target Staking Volume in the protocol for the next month
  • Target all-in APY that month and average interest rate on loans in the pool

Target Staking Volume size

The Staking Reserve provides additional collateral protection in case of defaults on the undercollateralized loans in a Lending Pool. The target reserve size is 5-7.5% of the balance of loans in a pool. The MPL rewards would be sized to hit the target all-in APY if actual staking volume meets the target reserve size. Eg if a pool has $100M of loans, then $5M-$7.5M staking reserve.

Target all-in APY

The target all in APY incorporates the USDC fees earned for staking plus MPL rewards. Current market conditions for stablecoin farming are generally 15-20% APY. The Staking Reserve receives 0.1x or 10% of the interest yield in the pool as fees.

  • If the average interest rate on loans in the pool is 10%, then 1% (ie 0.1*10%) goes to the reserve as fees.
  • If the Staking Reserve is 6% of the loans outstanding, then USDC fee APY is 16.67% (ie 1% / 6%).
  • Thus to achieve the target all-in APY of 15-20%, the target MPL rewards would be 5%-7.5% and the number of MPL deposited at the start of the month would be set accordingly.
