First of all, I have already searched on Google, and I didn't find a clear answer.
What I would like to do : For example, I would like to make one swap on uniswap, and the second to sushiswap, in the same transaction, like this :
UNISWAP : ETH -> UNI
SUSHISWAP : UNI ( last output ) -> ALCX
I know it's possible by writing a smart contract, but I don't know at all how to do. Anyone has an idea ?
Thank you a lot.
