hey guys how can i check what is this number in pool ? anyone can help ? poocoin show us 23K but dextool 47K

Go on the explorer and check the pool's reserves

just guessing here, maybe one of them only accounts for ETH or actually priced token like USDC that has an api, the other uses the price of both tokens

its BSC

where i can check the pool in contract ?

go to the pair contract
