The deposit token for the lp-ycrv vault is the crv... @yearnfinance

Answer: Staking lp-ycrv gives you the opportunity to earn rewards from the Compound Finance protocol. When you stake lp-ycrv, you are locking up your crv/ycrv LP tokens on the Compound Finance protocol, which then earns you interest in the form of Compound Tokens (cTokens). This means that the more you stake, the more rewards you will earn, as the cTokens will compound over time. Additionally, staking lp-ycrv gives you access to the Compound Governance Token (COMP), which can be used to participate in governance decisions on the Compound protocol.

So what do I gain if I stake lp-ycrv?
