Launch pool

#uniswap

Hint

You should be familiar with sqrtPriceX96 and how Usniswap works to solve this challenge.

Answer

The problem lies in the sqrtPriceX96 check. Roughly speaking, the price of a token at the moment of pool launch should be equal to the current token price. So what can go wrong? In general, any user can put any number of tokens into the pool and ‘knock down’ the current value of sqrtPriceX96, thus preventing the pool from starting. In this way it is possible to DoSS the protocol system and harm other users.
