# Plasma plAssets

Treveen earn on Plasma introduced plUSD and splUSD, offering competitive yield for stakers.

Built on the [Midas](https://midas.app/) Vaults Infrastructure, Trevee Earn aims to establish itself as the premier medium of exchange within the Plasma ecosystem.

***

All assets deposited into Trevee Earn Plasma flow into Midas Vault. The curators (Midas and Mithras) allocate these assets to whitelisted strategies deemed to be the safest possible in DeFi. Midas Vaults were chosen as they are a battle-tested solution that has been audited and are used to secure approximately $1.5B of assets.

## How it works ?

When minting plUSD tokens with USDT on Plasma, Trevee protocol automatically sends the underlying Stablecoins to a Midas vault (on Plasma mainnet) where it will be put to work in farming strategies using protocols like Aave, Fluid, and more. The yield generated by these farming strategies is continuously auto compounded within the Midas vault to increase APY, and all the yield generated by the mainnet Midas vault is swapped in stablecoins to mint new plUSD that will be sent to plUSD staking Contract (splUSD) as auto-compound rewards.
