RE: Expected return of the new reward pool

So, if I want to participate in the pool I simply go to Tribaldex -> Swap -> Add liquidity?

Exactly, that's the only thing that you have to do. After that you will get dividends according to your percentage in the pool.

The liquidity pool stays the same. The only think that changes will be the reward pool attached to it. For people providing liquidity, they don't have to do anything. Simply when we switch the reward pool, the reward will come from this new one.
