Harvest Finance is a yield farming protocol designed to auto compound users' rewards.
The CRV:stETH vault utilizes the Curve liquidity mining program to farm LDO and CRV, alongside an added incentive of FARM tokens which were allocated to the vault rewards by Harvest Finance. The strategy periodically sells LDO and CRV, whereas FARM rewards are kept for the user to manually claim.
To use the Harvest vault:
Scroll down to the ETH 2.0 section and locate the CRV:stETH pool.
Deposit the amount desired.
Approve and finalize the transaction.
You are now staking and auto-compounding your farmed rewards!
