Solidly is a dex synthesized by uni and crv. If you choose variable token when adding lp, you will use uni's xy=k. If you add lp and choose stable coin, you will use curve's x3y+y3x=k. The distribution of solid tokens is not available for every LP. Only LPs whose vesolid tokens are pressed will issue solid. Then the transaction fee of solid will be given to those who bet on vesolid, and lp can only take solid tokens. 

Solidly also has the function of bribe, that is, anyone can add bribe to an LP, which is represented by any number of arbitrary tokens. This bribe is not to bribe the LP, but to bribe the vesolid holder to press the vesolid to the LP, which will stimulate people to add lp, get solid income, and the token used for bribe will be given to those who bet.

The distribution of solid depends on how many people lock solid into vesolid. The more people lock it, the slower the issuance will be. If no one locks it, the token issuance will be large.
