Depending on the type of Liquidity Positions that are used, there are two different possibilities:
Non-staked Liquidity Positions
All yield comes from trading fees that Traders pay when they swap through the underlying AMM pools.
Staked Liquidity Positions
Holders of staked positions, such as staked Aerodrome, receive token emissions.
Depending on the staking mechanism these emissions can be on top of the yield from trading fees. Or as is the case with Aerodrome, stakers choose to earn emissions instead of trading fees.
What are the risks
All Strategists are exposed to the following risks:
Smart contract risks
Market risks
Impermanent loss
And depending if they use leverage or not:
Interest rate risk (interest rate can exceed yields)
