#### Get the Exchange Price in the Pool

As we explained before, when we use the token address (there are two: tokenIn and tokenOut) and the rate setting, we can get the exchange pool (smart contract) address of this exchange portfolio from the ```getPool``` method of the ```Factory``` contract of ```Uniswap```.
Once the pool address is obtained, the ABI of the pool contract is registered and the ```slot0``` method of the pool contract can be called to get the data related to the current exchange price and further resolve the exchange price.
