I want to know the address of an Uniswap pair contract with Solidity, even if the pair doesn't exist yet. I can't use the function getPair of the factory contract because it return 0 when the pair doesn't exist
So I need to calculate it on my code, I checked this page : https://uniswap.org/docs/v2/smart-contract-integration/getting-pair-addresses/ and it seems to be this :
address pair = address(uint(keccak256(abi.encodePacked( hex'ff', factory, keccak256(abi.encodePacked(token0, token1)), hex'96e8ac4277198ff8b6f785478aa9a39f403cb768dd02cbee326c3e7da348845f' ))));
However when I put this in solidity I have the error : Explicit type conversion not allowed from "uint256" to "address"
Any idea why ?
