Celer has built an L2 rollup for farming that aggregates users movements and executes them together, saving on fees.
It works like a bus, if 3 people want to move their farming from AAVE to curve, celer aggregates that into a single tx (avoiding 2 txs) 👇

The way it works is that once you have deposited money on the rollup, you can decide in which protocol you want to farm with your money, then you can move your assets between these only paying rollup fees (much lower since only calldata needs to be sent to L1) 
Then, every 6 hours, all the user changes are aggregated together and funds are moved from protocol to protocol in L1 (eg: if a person chooses to move 30$ from aave to curve and another wants to move 20$ from curve to aave, 10$ will be moved from aave to curve in 1 tx)
This kind of cost savings are similar to yearn's, where by aggregating money it allows fixed costs like gas to go down in relative terms, but here you retain full control of your money
On top of that, movements are completely trustless, since it's all secured by an optimistic rollup.
However, the contract has some code that allows owner to drain everything, and the owner is a normal wallet without timelock, so it all could be stolen instantly.
