F (x) v2 actually has a flaw compared to V1, as v2 relies on the liquidity of underlying assets, while v1 does not. In other words, v1 has a byproduct of LSD replenishing liquidity, which is why @ Lido Finance participates in the voting market for f (x). At v2, the poor backend doesn't look so strange anymore, but it has also standardized the product as a pure graded fund.
